Tagged: corsair, force ls, ssd, phison, toshiba mlc
Corsair has launched a new line of budget solid state drives (SSDs) under the Force LS branding. The new SSDs come in up to 240GB capacities, and despite being budget drives, still manage to max out the SATA III 6Gbps interface.
The new Force LS SSDs use 19nm Toshiba MLC NAND flash and a Phison SSD controller. Traditionally, Corsair has used LSI SandForce controllers in its Force and Force GT solid state drives. The Force LS line includes 60GB, 120GB, and 240GB SSDs. The drives are 7mm thick 2.5” form factor drives.
As far as performance, the drives support sequential write speeds of 535 MB/s and sequential read speeds of 555 MB/s. Information on IOPS have not been released, but expect it to be lower than the existing Force drives due to their budget nature.
There is no word on specific availability date(s), but the new Force LS drives will be priced at $70 for the 60GB, $110 for the 120GB, and $200 for the 240GB. At the top end, the drives are approximately 83 cents per Gigabyte ($0.83/GB). All Force LS drives come with three year warranties.

Tagged: exFAT, Samsung
But Linux distributions still cannot officially use it... sort of?
Samsung added support for exFAT on Linux, in kernel, with one of their tablets. At some point code was leaked on GitHub. At some other point the Software Freedom Conservancy determined certain GPL-dependent modifications were published in binary form alone. Eventually Samsung properly released their source code under the GNU General Public License (GPL).
I am still unclear about how Samsung was allowed to do so, however. Copyright was never the main concern with exFAT but rather the patents Microsoft holds over the file system. The GPL mandates that code it covers must come with a non-exclusive worldwide and royalty-free license for applicable patents except under certain conditions. I would be curious how this license was accomplished unless Microsoft granted Samsung a patent license prior to March 28, 2007 (or some loophole like that).
I understand how people might be sympathetic to Microsoft and others asserting software patents because they are a for-profit business but that does not apply everywhere. You need to be careful when you apply a license to something as upstream as a file system or a kernel as everything downstream relies upon your decision.
Just imagine if you were separated from the contents of your SDXC card because, somehow, this patent found its way into the portfolio of a troll firm?
Current implementations of the file system are in user space until Samsung's in-kernel module. The Software Freedom Conservancy praised Samsung -- not only for their source code contribution -- but also for how open and public their response was.

Tagged: Samsung, charge trap flash, vertical nand, vnand, 128Gb, enterprise ssd
Last week, Samsung announced that it had started producing a new stackable NAND flash memory called V-NAND, or vertical NAND. The new 3D V-NAND would initially be available in 128Gb (Gigabit) chips, but could eventually scale into as much as 1 Tb (Terabit) per chip by stacking additional dies vertically. Doing so allows Samsung some flexibility in scaling to higher capacities without going to increasingly expensive and difficult to manufacturer smaller manufacturing processes, which has been the traditional method of attaining denser flash.
The company has now announced the V-NAND SSD, which is its first Solid State Drive to use the Vertical NAND technology. Aimed at the enterprise server market, the V-NAND SSD will come in 480GB and 960GB capacities. The 2.5” form factor drives are 7mm thick and come equipped with a SATA III 6Gbps controller. On the high end, the 960GB model uses 64 MLC 3D V-NAND 128Gb dies for a total physical capacity of 1TB. However, user-accessible capacity will be only 960GB. Unfortunately, Samsung did not reveal how many physical chips the drives use, so its hard to say how those 64 128Gb dies are distributed (4 high in 16 chips or 8 high in 8 chips, etc).
The 960GB Samsung V-NAND SSD spotted by Engadget.
Samsung claims that the V-NAND SSD offers up to 20% increased performance and a 40% reduction in power consumption versus previous SSDs. Further, the 3D NAND using Samsung’s Charge Trap Flash technology is rated at 35K program erase cycles. Samsung rates the V-NAND memory itself as being twice as fast in writes and between two and ten times as reliable versus traditional 19nm floating gate NAND (the alternative to CTF NAND).
Samsung's 128Gb V-NAND die.
Samsung stated in a press release that it started production of the V-NAND SSD earlier this month. While it is introducing V-NAND into enterprise drives first, the technology will eventually trickle down into consumer drives. I’m interested to see this drive benchmarked for performance and write endurance to see if the 3D flash lives up to its potential.

Tagged: ssd, partition, MiniTool Partition Wizard Home Edition, 4k
SSDs and modern OSes no longer use the old 512 byte LBA alignment, or at least they don't need to and in the case of SSDs offer larger disk size and faster performance. However many people are not aware of 4k alignment nor how to check if their SSD is aligned nor what to do even if they do know it is not aligned. Hardware.Info put together a short article on the steps to verify if your SSD is aligned as well as covering a free partitioning tool called MiniTool Partition Wizard Home Edition which will help you align your SSD as well as other tasks common to partitioning software. As with any major changes being made at this low a level, do realize that this could cause data loss, but aligning those sectors is a great IDEMA.
"When you copy the contents of a hard disk from a PC or laptop to an SSD you have to make sure that the placement of the partitions corresponds to the underlying hardware structure. The same is true for the latest generation of hard disks. Today we'll discuss what this so-called '4k alignment' really means and what you can do in order to prevent a decrease in performance."

Tagged: ssd, silicon motion, sata, controller
You may very well have never heard of Silicon Motion (SMI), a major priducer of flash memory controllers, even if you've followed the SSD industry for a while. This is primarily because the vast majority of their products have been tailored for the devices that folks tend to not crack open during review, namely USB memory sticks, eMMC devices, and SD / CF cards:
Creating controllers in those arenas will tend to force a company to do a few things very well:
- Handle a very limited number of flash channels with the greatest speed possible, due to packaging requirements for very small devices.
- Operate at the lowest power draw possible as to meet the current draw limits of the host interface.
This has resulted in SMI developing a 6Gb/sec SSD controller, dubbed the SM2246EN, using the above techniques:
The block diagram shows what appears to be a fairly standard 4-channel configuration, though there are fewer steps in the pipeline as compared to SandForce and other controllers, which should help decrease latency and improve efficiency. There is also no compression engine, which means power consumption should be further reduced.
Read on for further details on specs and power consumption, followed by the full press blast.

Tagged: diablo technologies, DIMM, nand, flash memory, memory channel storage
Ottawa-based Diablo Technologies unveiled a new flash storage technology yesterday that it calls Memory Channel Storage. As the name suggest, the storage technology puts NAND flash into a DIMM form factor and interfaces the persistent storage directly with the processor via the integrated memory controller.
The Memory Channel Storage (MCS) is a drop-in replacement for DDR3 RDIMMs (Registered DIMMs) in servers and storage arrays. Unlike DRAM, MCS is persistent storage backed by NAND flash and it can allow servers to have Terabytes of storage connected to the CPU via the memory interface instead of mere Gigabytes of DRAM acting as either system memory or block storage. The photo provided in the technology report (PDF) shows a 400GB MCS module that can slot into a standard DIMM slot, for example.
Diablo Technologies claims that MCS exhibits lower latencies and higher bandwidth than PCI-E and SATA SSDs. More importantly, the storage latency is predictable and consistent, making it useful for applications such as high frequency stock trading where speed and deterministic latency are paramount. Further, users can get linear increases in throughput with each additional Memory Channel Storage module added to the system. Latencies with MCS are as much as 85% lower with PCI-E SSDs and 96% lower than SAS/SATA SSDs according to Diablo Technologies. NAND flash maintenance such as wear leveling is handled via an on-board logic chip.
Diablo Technologies is also aiming the MCS technology at servers running big data analytics, massive cloud databases, financial applications, server virtualization, and Virtual Desktop Infrastructure (VDI). MCS can act as super fast local storage or as a local cache for external (such as networked) storage in the form of mechanical hard drives or SSDs.
Some details about Memory Channel Storage are still unclear, but it looks promising. It will not be quite as fast in random access as DRAM but it will be better (more bandwidth, lower latency) than both PCI-E and SATA-connected NAND flash-based SSDs. It would be awesome to see this kind of tech make its way to consumer systems so that I can have a physical RAMDisk with fast persistent storage (at least as far as form factor, MCS uses NAND not DRAM chips).

ASUS has officially launched its PCI-E based ROG RAIDR Express SSD which was first shown off at CES 2013. The company posted details and high resolution photos on its Republic of Gamers blog on Friday.
The new PCI-E-based solid state drive measures 157 x 120 x 20mm and contains 240GB of NAND flash encased in a sleek metal Replublic Of Gamers themed exterior. Specifically, the RAIDR Express uses 19nm Toshiba synchronous MLC NAND flash and two LSI SandForce 2281 SSD controllers. As such, the drive is actually two SSDs that are placed in a RAID 0 configuration for the best performance. ASUS rates the drive at 830 MB/s sequential reads and 810 MB/s sequential writes. The PCI-E SSD is further capable of up to 100,000 4K random IOPS.
ASUS has also included what it is calling a "DuoMode" BIOS switch that allows the drive to be used with either legacy or modern UEFI BIOSes. When the switch is in the EUFI position, PCs with the modern UEFI-equipped motherboards can boot up faster.
Beyond the RAIDR Express SSD itself, ASUS includes the following bundled software packages:
- RAMDisk software
- HybriDisk caching software
- SSD TweakIT utility
ASUS is including RAMDisk software that is able to use as much as 80% of system RAM as a virtual drive that can be used to reduce wear on the SSD by using the RAM drive instead of the SSD for writing temporary files and the like. The above mentioned HybriDisk software allows the RAIDR Express SSD to be used as a cache drive for mechanical hard drives up to 4TB in capacity. Users can use the TweakIT utility to manage and optimize the SSD, and the CrystalDiskMark benchmark is being included to allow gamers to run benchmarks on the RAIDR Express to get an idea of its performance.
Oddly enough, ASUS has yet to release specific pricing or availability. More information along with the full press release can be found on the Republic of Gamers blog, however.
With that said, some sites are reporting that the RAIDR Express will be sold for around 440 Euros, which works out to about $600 USD or $2.5 per Gigabyte. Update: Commentor Roberto has pointed out that the RAIDR Express 240GB is available over in Japan for around 39,980 Yen, or ~$409 USD which is a much more reasonable price. US availability and pricing are still just estimates at this point, however. A bit on the expensive side (if the price is true) for sure, but it is nice to see another player in the PCI-E SSD space and it looks to be a speedy drive aimed at ROG fans and enthusiasts.

Tagged: TurboWrite, tlc, ssd, slc, Samsung, 840 evo, MEX controller
Along with Al's review of the new EVO line you can get a second opinion from The Tech Report about the performance of the new SSD with a fast cache. The majority of the storage is 19nm TLC NAND but there is an SLC cache sitting between the controller and that long term TLC storage to help with the overall responsiveness of the drive, aka TurboWrite. In the 120 and 250GB models that cache is 3GB while in the larger models you get a 6GB cache. In their real world testing the new EVO drive is incredible at large file copying though Sandforce drives can beat it in small file copy speeds, likely thanks to the compressed write trickery that controller family is so good at. Check out the review here and keep your fingers crossed that MSRP is the acual price these drives sell at.

Tagged: turbo sshd, sshd, Seagate, nand, enterprise
Earlier this week Seagate took the wraps off of its latest Solid State Hybrid Drive (SSHD). Dubbed the Enterprise Turbo SSHD, this latest model is aimed at the enterprise server market. The drives combine a traditional 10K SAS mechanical hard drive in capacities up to 600GB with up to 32GB of NAND flash.
The 2.5" Enterprise Turbo SSHDs are aimed at servers with big data analytics, virtual desktops, and transaction processing workloads. The NAND flash acts as a cache for the mechanical hard drive, and caching is done by the controller at an I/O level.
According to Seagate, the company has been working with IBM over the past year to put the new SSHD through its paces. As such, the hybrid drives will first be available in the IBM X and BladeCentral servers. The IBM versions will have 16GB of NAND flash and one year warranties according to the documentation available online.
Seagate further claims up to three times random performance increase versus 15K SAS mechanical hard drives. The 600GB 10K SSHD is rated to have up to two times better IOPS than a traditional 10K SAS hard drive without a NAND cache.
The Enterprise Turbo also comes with enterprise-friendly drive self encryption options. The Seagate product page notes that the Enterprise Turbo SSHD will have a five year warranty. Pricing and detailed benchmarks are not yet available though some preliminary performance results can be found here.

Adam DeConinck, high performance computing (HPC) systems engineer for NVIDIA, built a personal computer cluster in his spare time. While not exactly high performance, especially when compared to the systems he maintains for Amazon and his employer, its case is made of Lego and seems to be under a third of a cubic foot in volume.

Raspberry Pi is based on a single-core ARM CPU bundled on an SoC with a 24 GFLOP GPU and 256 or 512 MB of memory. While this misses the cutesy point of the story, I am skeptical of the expected 16W power rating. Five Raspberry Pis, with Ethernet, draw a combined maximum of 17.5W, alone, and even that neglects the draw of the networking switch. My, personal, 8-port unmanaged switch is rated to draw 12W which, when added to 17.5W, is not 16W and thus something is being neglected or averaged. Then again, his device, power is his concern.
Despite constant development and maintenance of interconnected computers, professionally, Adam's will for related hobbies has not been displaced. Even after the initial build, he already plans to graft the Hadoop framework and really reign in the five ARM cores for something useful...
... but, let's be honest, probably not too useful.

Tagged: nand, micron, flash, 16nm
Micron recently announced that is has begun sampling 16nm NAND flash to select partners. Micron expects to begin full production of the NAND chips using the smaller flash manufacturing process in the fourth quarter of this year (Q4 2013). Drives based on its new 16nm MLC NAND flash are expected to arrive as early as next year. (PC Perspective's own storage expert is currently overseas, but I managed to reach out over email to get some clarification, and his thoughts, on the Micron annuoncement.)
The announcement relates to new NAND flash that is smaller, but not necessarily faster, than the existing 20nm and 25nm flash chips used in current solid state drives. In the end, Micron is still delivering 128Gb (Gigabit) per die, but using a 16nm process. The 16nm flash is a pure shrink of 20nm which is, in turn, a shrink of 25nm flash. In fact, Micron is able to get just under 6 Terabytes of storage out of a single 300mm wafer. These wafers are then broken down into dies in individual flash chips that are used in all manner of solid state storage devices from smartphone embedded storage to desktop SSDs. This 16nm flash still delivers 128Gb --which is 16GB-- per die allowing for a 128GB SSD using as few as eight chips.
A single 16nm NAND flash die with a SSD in the background
Micron expects the 16nm MLC (multi-level cell) flash to be used in consumer SSDs, USB thumb drives, mobile devices, and cloud storage.
The 16nm process will allow Micron to get more storage out of the same sized wafer (300mm) used for current processes, which in theory should mean flash memory that is not only smaller, but (in theory) cheaper.
A single wafer of 16nm NAND flash (just under 6TBs)
As Allyn further notes, the downside to the new 16nm NAND flash is a reduction in the number of supported PE cycles. Micron has not released specific information on this, but the new 16nm MLC flash is expected to have fewer than 1,000 P/E cycles. For comparison, 25nm and 20nm flash has P/E cycles of 3,000 and 1,000 respectively.
In simple terms, P/E (program-erase) cycles relate to the number of times that a specific portion of flash memory can be written to before wearing out. SSD manufacturers were able to work around this with the transition from 25nm to 20nm and still deliver acceptable endurance on consumer drives, and I expect that similar techniques will be used to do the same for 16nm flash. For example, manufactuers could enable compression that is used prior to writing out the data to the physical flash or over-provisioning the actual hardware versus the reported software capacity (ie a drive sold as a 100GB model that actually has 128GB of physical flash).
I don't think it will be a big enough jump that typical consumers wil have to worry too much about this, considering the vast majority of operations will be read operations and not writes. Despite the reduction in P/E cycles, SSDs with 16nm NAND MLC flash will still likely out-last a typical mechanical hard drive.
What do you think about the Micron announcement?

Tagged: tlc, ssd, slc, sata, Samsung, cache, 840 evo
Samsung's release of the 840 EVO earlier today likely prompted some questions, such as what type of flash does it employ and how does it achieve such high write speeds. Here is the short answer, with many slides in-between, starting off with the main differences between the 840 and the 840 EVO:
So, slightly increased specs to help boost drive performance, and an important tidbit in that the new SSD does in fact keep TLC flash. Now a closer look at the increased write specs:
Ok, the speeds are much quicker, even though the flash is still TLC and even on a smaller process. How does it pull off this trick? Tech that Samsung calls TurboWrite.
A segment of the TLC flash is accessed by the controller as if it were SLC flash. This section of flash can be accessed (especially written) much faster. Writes are initially dumped to this area and that data is later moved over to the TLC area. This happenes as it would in a normal write-back cache - either during idle states or once the cache becomes full, which is what would happen during a sustained maximum speed write operation that is larger than the cache capacity. Here is the net effect with the cache in use and also when the cache becomes full:
For most users, even the smallest cache capacity will be sufficient for the vast majority of typical use. Larger caches appear in larger capacities, further improving performance under periods of large write demand. Here's the full spread of cache sizes per capacity point:
So there you have it, Samsung's new TurboWrite technology in a nutshell. More to follow (along with a performance review coming in the next few days). Stay tuned!

Tagged: sandisk, Extreme II series, ssd, mlc, slc
SanDisk has done something interesting with their new Extreme II SSD series, they have used both SLC and MLC flash in the drive to attempt to give users the best of both worlds. The drive still has a DDR cache sitting between the flash storage and the controller, but there is an nCache between the MLC flash and the DDR comprised of ~1GB of SLC flash. The idea is that the SLC can quickly accumulate a number of small writes into a larger single write block which can then be passed to the MLC flash for storage. Don't think of it as a traditional cache in which entire programs are stored for quick access but more as a write buffer which fills up and then passes its self to the long term storage media once it is full. The Tech Report put this drive through their tests and found it to be a great all around performer, not the fastest nor the best value but very good in almost any usage scenario.
"With MLC main storage and an SLC flash cache, the SanDisk Extreme II is unlike any other SSD we've encountered. We explore the drive's unique design and see whether it can keep up with the fastest SSDs on the market."

If you buy a machine with an SSD installed inside of it there is a good chance it is from Toshiba and it might even be the THNSNH 256GB model. As these drives are not sold separately but only inside OEM machines it is not often benchmarked. [H]ard|OCP wants to change that and put this drive and its internally designed controller up against some of their favourite retail drives. Their testing revealed a mixed bag of performance as in some tests it came close to beating out Samsung's 840 series but in other testing ended up at the bottom of the pack. Still, as this drive will end up in many mobile devices it is good to get an idea of the performance you can expect from it.
"Toshiba's massive foundry capabilities allow it to develop some of the leading SSDs for the OEM market. These SSDs come pre-installed in the latest computers with the option for an SSD, and today we look at the Toshiba THNSNH in comparison to current top-flight enthusiast-class SSDs."

We caught wind of a leaked Intel SSD Roadmap over at VRZone. The slide shows their rough release plans into early 2014:
Starting bottom-up, the old 320 Series (cropped slide bottom) and 330 Series are being phased out in light of the newer 500 series entrants. The 335 Series, driven by a SandForce controller and 20nm flash, may drop in capacity to only an 80GB model in order to drive customers towards the new 530 Series, which will replace both of the SandForce-driven 520 (SATA) and 525 Series (mSATA) offerings. The new 530 Series will be available in 80-480GB and connect via SATA, mSATA, and the newest M.2 SATA interfaces. You can learn more about M.2 by reading the first 6 or so slides from Paul Wassenberg's presentation from Storage Visions 2013. Here's a closer look at an M.2 unit:
From CES 2013, a Micron mSATA SSD (above) and M.2 SATA SSD (below).
With the 530 appearing to become Intel's big mainstream consumer push, they will also introduce a Pro 1500 and 2500 Series. I suspect Intel's own SATA 6Gb/sec controller will be lifted from their SSD DC S3500 and S3700 Series and trickled down into the Pro Series and possibly even into the 530 Series, though that is only speculation on my part.
For the enterprise, Intel will be further juggling their enterprise models around a bit, discontinuing the SSD 710 and possibly even the (25nm) S3700 in favor of the (20nm) S3500 Series, which will also see large gains in available capacity upwards of 800GB and even 1.6TB crammed into a 2.5" SATA unit. Intel's PCIe SSD 910 will eventually be replaced by what appears to be a quad-SSD-RAID variant of the current S3500 and S3700 Series units, dubbed P3500 and P3700, respectively. These models should show a substantial gain over the SSD 910, which did not perform spectacularly when compared to the newer SATA models available.

IRVINE, Calif. – June 27, 2013 – WD®, a Western Digital (NASDAQ: WDC) company and world leader in digital storage solutions, today unveiled the fourth generation of WD Arkeia™ network backup appliances, delivering an all-in-one backup and disaster recovery solution for small- and medium-sized businesses (SMBs).
The new line up consists of four rack-mount appliance models with larger internal disk capacities, faster processors, increased memory, and integrated solid state drives (SSDs) to shorten backup time and accelerate data recovery. The bundled WD Arkeia v10.1 software delivers new support for “seed and feed” technology to support hybrid cloud backups. This allows companies to move backups offsite via network replication rather than shipment of tapes.
“In announcing their fourth generation of purpose-built network backup appliances, WD Arkeia is delivering comprehensive SMB backup solutions that go beyond simple raw capacity increases,” said Liz Conner, senior research analyst, IDC. “WD Arkeia offers easy- to-use data protection that takes the guess work out of purchasing, configuring and managing data backup and recovery, while also embedding features such as deduplication and hybrid cloud backup for small- and medium-sized businesses or remote offices." “WD is committed to providing the growing SMB marketplace with a comprehensive suite of storage solutions,” said Jim Welsh, executive vice president and general manager of WD’s branded business unit. With unique features, these next-generation WD Arkeia network backup appliances offer solutions providers and their customers a simple, smart way to protect their data.
Fourth-Generation Performance and Ease-of-Use
Fourth-generation WD Arkeia backup appliances deliver performance and ease-of-use at an affordable price for SMBs. These new appliances extend the upper range of WD Arkeia appliances and complement available lower-range appliances. WD Arkeia R120s and R220s, both with optional LTO4 tape drives, integrate dual-core Atom and quad-core Xeon processors, respectively. Existing appliances deliver disk capacities from 2TB to 12TB and will also bundle WD Arkeia v10.1. The new fourth-generation appliances offer: o Increased Backup and Recovery Speed: New features include integrated LTO5 tape drives, processor upgrades to a maximum of 2 hex-core Intel® Xeon®, integrated SSDs on select models, and memory up to 96 GB to allow for increased data backup and recovery speeds of both files and disk images. WD Arkeia’s patented Progressive Deduplication™ technology accelerates backups by compressing data at source computers before transfer over local area networks (LANs) or wide area networks (WANs).
- Higher Storage Capacity: Storage capacity doubles from the third generation, with raw capacity now ranging up to 48 TB, configured in RAID-6.
- Improved Ease of Use: Version 10.1 of WD Arkeia software, delivered with the new generation, includes an on-boarding wizard to streamline the appliance setup process.
- Storage Reliability: All new WD Arkeia appliances feature WD enterprise-class WD RE™ hard drives for maximum data integrity.
- Simplified Tape-free, Offsite Storage: Version 10.1 of WD Arkeia software extends support for hybrid cloud backup capabilities to the full line of WD Arkeia appliances. “Seed and feed” capabilities allow administrators to supplement network replication of backup sets offsite by using USB-connected hard drives to transfer initial and large backup sets and also to size WAN bandwidth for the replication of nightly incremental backups.
Pricing and Availability
WD Arkeia fourth generation network backup appliances – models RA4300, RA4300T, RA5300, RA6300 – will be available in July 2013 through select DMR’s and WD-authorized value-added resellers (VARs) in the US, Canada, and Europe. Manufacturer’s Suggested Retail Price, including hardware and software, begins at $9,990 USD. WD Arkeia network backup appliances are covered by one year of unlimited access to technical support, one year of software updates, and a one-year limited hardware warranty.

Tagged: LAMD Amber, corsair, neutron gtx
Corsair's Neutron GTX has 240GB of 19nm MLC NAND with a LAMD Amber controller, similar to the previous model but with process shrunk RAM. Write speeds do suffer from the new flash, but that will only be noticeable during large file transfers not during normal usage scenarios. On the other hand [H]ard|OCP noticed many performance increases which were due to the LAMD Amber controller and netted this drive a Silver award. The SSD market is very large, with many makes and models available; this drive is worth putting on your short list.
"Corsair moves to a smaller 19nm Toshiba Toggle MLC NAND with its LAMD-controlled Neutron GTX Series of SSDs. This shrink comes amongst stiff competition from other manufacturers, and a new SSD that is very similar to the Neutron GTX. Today we see how the new GTX stacks up against its increased competition."

As Scott covered earlier this week, Apple quietly announced an update to the MacBook Air line along side the headline-grabbing Mac Pro redesign preview. Being a MacBook Air user for the past 2 years, I decided it was time to replace my Sandy Bridge-based model with some new Haswell goodness. Today marked the first day of retail store availability, and I picked up an 11" model with 256GB SSD.
Naturally, when I got back to the office there was only one route to take, installing Windows and disassembling it. While Anand uncovered the fact that these MacBooks were hiding a new unadvertised option, in a PCI-Express based SSD, I wanted to check it out for myself.
When I did some digging, I discovered that while Anand found a Samsung based SSD in his MacBook, mine actually contained a model by Sandisk. I did a quick initial benchmark in OS X, and proceeded to inspect the hardware itself.
