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!

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."

Tagged: toshiba, THNSNH 256GB, ssd
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.

Tagged: Seagate, NAS
CUPERTINO, Calif.--(BUSINESS WIRE)-- Seagate Technology (NASDAQ:STX) today took the wraps off its new Seagate® NAS HDD—a cutting-edge drive custom-built for always-on, one- to five-bay network attached storage (NAS) systems. Engineered with performance and reliability in mind, the new drives are available in multiple capacity points including a 4TB option—the industry’s highest capacity NAS hard disk drive (HDD) solution available—and strong industry support from nine NAS system partners.
“Today about 50 percent of NAS arrays are sold diskless meaning that customers are challenged with identifying and installing the right storage for their system. By developing a drive like NAS HDD, we’ve taken the guesswork out of it and made it easy for customers to identify the right drive for their system,” said Scott Horn, Seagate vice president of marketing. “By collaborating closely with a variety of partners who specialize in NAS systems, we’re making what was a confusing effort into a plug-and-play one.”
Featuring up to 4TB of storage the drive now enables NAS systems, such as those utilized in homes and small to midsize businesses (SMB), to provide up to 20TB of data in a five-bay NAS array. And with over 30 percent capacity improvement over competitive offerings, the NAS HDD 4TB drive delivers the highest capacity available on the market.
Cost effective drives built specifically for NAS solutions, the 4TB option has the capacity to store over 819,000 photos, 1 million songs or nearly 500 hours of high-definition (HD) video content—more than enough space for the average household. It is also ideal for small businesses with large enough capacities to support CAD files, medical images and databases.

SanDisk claims their Extreme II can run at 550/510 MB/s sequential read/write, and 95,000/78,000 for random read/write IOPS, a claim which [H]ard|OCP just put to the test. The two major changes to this drive that will contribute to the difference in speed are the switch from a Sandforce controller to the Marvell 9187 controller and the MLC flash which is 19nm in this drive. Testing shows that the drive does live up to expectations though they did point out the lack of encryption as a weakness. Prices for the drives are around the magic $1/GB mark, making this drive a solid contender in a very populous market.
"SanDisk releases its Extreme II series SSD, which features the Marvell 9187 controller in concert with 19nm eX2 ABL MLC NAND.

San Jose-based storage manufacturer Super Talent has announced its new UltraDrive MX3 SSD. This new drive is the successor to the existing UltraDrive MX2, and is allegedly twice as fast. In an interesting twist, Super Talent is releasing the MX3 in both MLC and SLC flavors, to serve the consumer and enterprise markets simultaneously with the same branded drive and controller.
The MX3 is a SATA 3 6Gbps drive that is rated at 500MB/s reads and 400MB/s writes. The MLC version will come in capacities ranging from 64GB to 512GB while the SLC flash SKUs top out at 256GB. The chart below details the model numbers at each capacity point for both the MLC and SLC SKUs, depending on what you need.
In the press release, Super Talent CEO Abraham Ma stated the following:
“We are excited to introduce the MX3. Not only does it offer a considerable upgrade in speed from its predecessor, the MX2, it is also an extremely reliable device that we believe fits the needs of our OEM and consumer customers.”
Pricing and availability have not been announced, however.

Tagged: ssd, crucial m500, mlc, marvell 9187, RAIN
Before discussing the impressive price point of Crucial's M500 drive their are two features worth mentioning about this drive, RAIN and the Marvell 9187 controller. RAIN is Redundant Array of Independent NAND which offers data parity which will allow you to successfully recreate data after an uncorrectable error, something which might put the minds of those still leery of SSDs to rest. The new Marvell controller is the secret to the pricing of this drive, it allows the usage of 128Gbit (16GB) NAND dies as opposed to the more common 64GBit dies and is produced at a lower cost than other controllers. [H]ard|OCP tested the 512GB drive and does warn that the specifications of the two smaller capacity drives are different enough to require individual testing. However as you can pick up the 512GB drive for $400 you might simply opt for the largest drive which offers competitive performance at an amazing $0.78/GB.
"Crucial's M500 offers the lowest price per gigabyte for an MLC SSD with enterprise-class features not seen on typical consumer SSD data drives. With new 128Gbit MLC NAND paired with the Marvell 9187 controller the M500 should deliver great performance at a historically low price point. Is the Crucial M500's performance up to par?"

Tagged: Xe, western digital, wdc, se, RE, hdd
Today Western Digital did a slight rearranging of their enterprise product lineup:
Starting from the top down, the Xe series is essentially a SAS version of their 2.5" 10k RPM VelociRaptor form factor, available in 300GB, 600GB, and 900GB capacities. The Re series is the same 'RE' we are all familiar with, and is now available in both SAS and SATA. That bottom block, however, is something new:
The Se series is Western Digital's attempt at a lower cost Re series drive, and will be available in capacities up to 4TB.
So the Se is an Advanced Format version of the Re, designed for reduced workloads. Throughput is slightly reduced due to differences in track geometry, though WD let me know they expect final shipping Se's may be closer to the Re spec than the slide indicates. The Se carries the same RPM as well as StableTrac (where the spindle is supported at both ends), RAFF (where accelerometers compensate for chassis vibration), and TLER (where IO request timeouts are adjusted to play nicely with hardware RAID).
The key to the success of the Se will be just what sort of reduced cost Western Digital is able to price the drive at. That information, as well as a full review of an Se, will be coming later today, just as soon as our next batch of samples arrives.

Hitachi Global Storage Technologies (HGST, which is now owned by Western Digital) has developed a new 2.5” mobile hard drive called the Travelstar 5K1500. The hard drive uses three 500GB platter drives for a total capacity of 1.5TB. HGST claims that the drive is the highest capacity 9.5mm mobile drive on the market. Additionally, the company has stated that the new drive is faster than its existing two-platter hard drives according to the PCMark Vantage and PCMark 7 benchmark suites.
The 1.5TB Travelstar 5K1500 is a 5400 RPM hard drive with 32MB of on-board cache, a 6Gbps SATA III interface, and shock protection features.
The new mobile drive will be used in external hard drives, all-in-one systems, and notebooks where storage space is valued more than pure performance. It will be available sometime in June for an as-yet-unannounced price point. Another version of the Travelstar 5K1500 that offers automatic encryption of data will be available in Q3 2013.

The Tech Report sat down with Matt Rutledge, Vice President of Western Digital's client computing group to discuss the software behind their new HDDs with an SSD cache. Sandisk will be providing the hardware and WD who will be providing the custom caching software which will not be coded into the hardware but will function at the driver level. Matt mentioned that this software can also make use of the system's memory and incorporate it into the cache as well though it was not completely clear if there will be many user editable settings. Check the interview out.
"WD revealed that its hybrid drives will use SanDisk iSSD flash components. The announcement was devoid of details on how the caching system works, but we can now shed new light on the software-managed scheme."

Tagged: ramdisk, ram drive, ram, radeon ramdisk, amd
In light of AMD’s latest memory release and Radeon RAMDisk push, I decided to take a look at the latest version 4.1.0 of the RAMDisk software to see what had changed since the last time I tested it out. Improved installation and logging along with a couple of new features are all part of the new RAMDisk software.
AMD has simplified the installer since the previous version to the point that only a few clicks are necessary to get setup. Although you can jump into the advanced settings and change the installation path, the default options are basically just to accept the ToS and click next. Other GUI tweaks include a new Logging tab that scans the last 1,000 entries in the Windows Event Log and shows only those related to the RAM Drive.
The biggest change is the addition of new options in the load/save tab. Because of the nature of RAM, the RAMDisk created by the software is not persistent across reboots. However, you can save the disk image to a file on persistent storage (a hard drive, SSD, et al). Then, you can save the RAM Drive and its contents to a file and reload that disk after a restart.
The paid version of Radeon RAMDisk takes this a step further by allowing background updating of the RAMDisk data. With the Load in Background option, the RAMDisk will be immediately available to the operating system after a restart. The software will automatically start transferring data from the image stored on the hard drive to the portion of RAM set aside for the RAM disk instead of making the user wait fro the entire disk to be recreated before it can be accessed. Any data requested that has not yet been transferred to the RAM disk will be transparently pulled from the hard drive image.
Further, AMD offers up a background update option that will run in the background and continuously write RAMDisk changes to the *.img file stored on the hard drive. This eliminates the need to wait for the entire RAMDisk to be written to disk before shutting down the computer or stopping the RAM Drive. Considering the wait times to read and write data from/to the hard drive is one of the major limitations of RAM drives, this is a really useful feature that certainly adds some incentive to springing for the paid version.
The free version doesn’t get background updating, but it does still have the AutoSave feature that will write data out to the image file periodically which will help prevent data loss due to power failure or kernel panic.
Heh, the SSD is pegged but the RAMDisk utilization peaked at 4% when copying a 1.51GB Kerbal Space Program (with a few mods installed) folder from an Intel X25-M to a 4GB RAMDisk ;).
In my brief testing yesterday, I had some trouble getting the software to create a FAT32 formatted disk, where it kept changing to unformatted before creating the disk. Eventually I opted to format the drive myself using Windows’ Disk Management utility. Aside from that hiccup, I think the new version is worth updating to if you have not already--especially if you have the paid version (so that you can get the background data transfer features).
For specific details on exactly what has changed, an AMD-provided change log is below:
Feature Highlights of AMD Radeon™ RAMDisk release 4.1
- Updated GUI improvements .NET
- Updated installer package – Fewer clicks required to install
- Improved GUI event logging
- Improved management of options when setting Load/Save
Performance Highlights of AMD Radeon™ RAMDisk release 4.1
- Performance gains on AMD Radeon™ RAMDisk 32GB and 64GB
- Vastly improved load and save mechanics allowing for background update and background loading of the RAMDisk. Reduces wait times for load and save. “Background Update” and “Load in Background” enabled (registered users only)
- Faster PC startup and shutdown while RAMDisk is enabled.
Improved IO performance on multi-processors and multi-core systems
- Evenly distributed load among the CPUs. Allows for more system efficiency.

Tagged: x8 accelerator, virident, ssd, seagate 1200, Seagate, pci-e
In addition to its recently-announced 600 and 600 Pro consumer line of solid state drives, Seagate has unveiled two new drives aimed at the enterprise SSD market. The Seagate 1200 series is a 2.5" SAS SSD and the Seagate X8 is a PCI-E based accelerator card.
Unfortunately, details are extremely scarce on both upcoming enterprise drives. Performance, specifications, pricing, and availability are still unknown. Seagate has officially confirmed there existence and shared a few tidbits of information, however.
The Seagate 1200 SSDs are 2.5" form factor drives with a 12Gbps SAS interface, which suggests that they will be at least somewhat faster than the consumer versions due to Seagate implementing the faster drive interface. The most important detail however, is that Seagate will be using its own custom SSD controller in the 1200 series. The new controller is still a mystery, but it is developed by Seagate and not Link A Media with customized firmware like the 600 and 600 Pro drives. I am especially interested to find out more about this aspect of the drive. Hopefully the new controller is successful and will trickle down to the company's next-generation consumer SSDs.
Meanwhile, Seagate's X8 Accelerator card is a half-height, half-length expansion card with up to 2.2TB of flash memory. The new PCI-E based drive is based on technology from Virident and can be used to accelerate applicators or database operations in servers. It will be available in capacities ranging from 550GB to 2.2TB. The SSD controller/management duties are handled by the host system's CPU and maintenance operations like garbage collection can be scheduled for periods of downtime when the server is not being hit hard by things like database requests for a popular web application. According to Seagate, each X8 Accelerator will be capable of up to 1.5 million IOPS.
Both of the new enterprise solid state drives will be released later this year.
Seagate has officially moved into the solid state drive (SSD) market with two new consumer drives: the 600 and 600 Pro series. The new drives come in capacities ranging from 100GB to 480GB. Both series utilize the Link A Media (LAMD) LM87800 SSD controller and 19nm 2-bit per cell MLC NAND flash from Toshiba. Seagate has not provided pricing or availability dates, but pricing should be in-line with existing drives, and reviews are already available around the Internet.
The Seagate 600 series is the lowest-tier solid state drive. It will be available in 120, 240, and 480GB capacities. Seagate is using 128GB, 256, and 512GB of NAND flash on 2, 4, and 8 channels respectively. In addition to the LM87800 SSD controller (which features custom Seagate firmware) and NAND flash, Seagate is including 1MB of DDR2-800 DRAM per 1GB of NAND flash for a total of 128, 256, and 512MB of DRAM on the 120, 240, and 480GB capacity drives.
The 600 Series is rated at up to 500MB/s peak 128KB reads and 400MB/s writes (limited to 300MB/s on the lowest-capacity 120GB drive). Further, Seagate states that the 120GB drive is capable of 80,000 random read and 60,000 random write (4K) IOPS, while the 240GB and 480GB drives can reach up to 80,000 random read and 70,000 random write (4K) IOPS.
Also note that the 600 series comes in both 7mm and 5mm form factors, which makes it compatible with most laptops. Seagate provides a 3 year warranty on the 600 series.
The Seagate 600 Pro series steps things up a notch by adding overprovisioning, capacitors for power-loss protection, and a longer 5 year warranty. The 600 Pro series will come in 100, 120, 200, 240, 400, and 480GB capacities. The 100, 200, and 400GB versions of the SSD offer additional overprovisioning which gives the SSD controller more space to work with. The capacitores are intended to provide enough power in the event of a PC power loss to write all data to the NAND flash and prevent data loss.
The 600 Pro drives offer the same 6Gbps SATA interface, LM87800 controller, and 1MB-to-1GB DRAM to NAND ratio. The Pro drives do not come in the 5mm high form factor, so laptop compatibility is limited.
Further, the 600 Pro Seagate SSDs are faster drives. According to Seagate, the Pro series offers up to 85,000 and 30,000 random read and write (4K) IOPS on the overprovisioned drives and p to 85,000/11,000 random IOPS on the 240 and 480GB drives. The 100 and 120GB drives are slower than the other drives though due to less NAND flash and channels between the flash and controller. The chart below details the rated specifications for all of the announced drives.
|Series||600 Pro||600 Pro||600 Pro||600 Pro||600 Pro||600 Pro||600||600||600|
|Random 4K r/w KIOPS||80/20||80/8||85/30||85/11||85/30||85/11||80/60||80/70||80/70|
|128KB r/w sustained sequential||>500/>300||>500/>400||>500/>400|
|128KB peak sequential r/w||520/300||520/300||520/450||520/450||520/450||520/450|
Blank areas indicate that rated specifications were not available.
Fortunately, the reviews available online (such as AnandTech's) do seem to support the new drives as far as performance is concerned. The drives are stacking up nicely versus the competition, which is interesting given the controller choice. For example, the sequential read speed looks promising.
The 600 and 600 Pro drives are looking like solid drives so long as the pricing is competitive. I'm excited to see where Seagate goes from here.
