Introduction, Specifications and Packaging
OCZ's RevoDrive series has been around for quite some time. We reviewed the first of the series over four years ago, and they just kept coming after that initial launch.
The full line of (now legacy) Revo / Z-Drive series products.
With the recent acquisition by Toshiba, it was only a matter of time before OCZ revamped the RevoDrive line with their new flash. It just makes sense, as Toshiba can be obtained much more readily (and cheaply) since they are now an in-house source for OCZ. With the Vector 150 and Vertex 460 already driving 19nm Toshiba flash, we now have the RevoDrive 350:
We suspected they might also count this as an update to the Revo line and not just a flash swap, so with a sample to test, let's see what's what!

You know the PCI-SIG might break the pattern with PCIe 5.0, just to mess with us. But for right now, Tom's Hardware seems to have acquired part of the PCIe 4.0 spec and it is expected to get 2 GB/s bandwidth per lane, per direction. This is double the bandwidth of PCIe 3.0, continuing the trend of each major PCIe release doubling bandwidth of the previous major version.
A 16-lane PCIe 4.0-compliant graphics card or storage add-in board (that feels so weird to write...) has a maximum bandwidth of 32 GB/s inbound and 32 GB/s outbound, 64 GB/s total. This is still below GDDR5 bandwidth, but approaching the same order of magnitude. That said, memory bandwidth is the major roadblock for optimizing GPGPU workloads, already. APUs will probably still have an advantage in CPU and GPU tag-teaming tasks, despite their lower compute performance.
According to bit-tech, the spec is expected to arrive with Skylake and its 100-series chipset.

ADATA has been showing off some upcoming products at Computex, and it's all about DRAM.
We'll begin with an upcoming line of PCIe Enterprise/Server SSDs powered by the SandForce SF3700-series controller. We've been waiting for products with the SF3700 controller since January, when ADATA showed a prototype board at CES, and ADATA is now showcasing the controller in the "SR1020" series drives.
The first is a 2TB 2.5" drive, but the interface was not announced (and the sample on the floor appeared to be an empty shell). The listed specs are performance up to 1800MB/s and 150K IOPS, with the drive powered by the SF-3739 controller. Support for both AHCI and NVMe is also listed, along with the usual TRIM, NCQ, and SMART support.
Another 2TB SSD was shown with exactly the same specs as the 2.5" version, but this one is built on the M.2 spec. The drive will connect via 4 lanes of Gen 2 PCI Express. Both drives in ADATA's SR1020 PCIe SSD lineup will be available in capacities from 240GB - 2TB, and retail pricing and availability is forthcoming.
Continuing the DRAM theme, ADATA also showed new DDR4 modules in commodity and enthusiast flavors. Both of the registered DIMMs on display (an ultra-low profile DIMM was also shown) had standard DDR4 specs of 2133MHz at 1.2V, but ADATA also showed some performance DDR4 at their booth.

No pricing or availability just yet on these products.

SATA Express is an interface to either connect a hard drive to PCIe lanes, or up to two drives via SATA. Obviously, PCIe bandwidth over a cable connection is the real draw. To use the full speed, however, the drive needs to be able to communicate over PCIe. Currently, the standard uses two PCI Express 2.0 lanes (1 GB/s).
Now that Z97 and H97 have launched, WD is set to show off the technology at Computex. The above image is apparently of a dual-drive product, containing 4TB of rotating media and 128GB of SSD memory. I am immediately reminded of the Western Digital Black2 dual drive which Allyn reviewed last November. That product crammed a 120GB SSD into a 2.5" 1TB HDD, which appeared to the system as two separate drives. The drive has "Technology Demonstration" written in red font right on it, but it could be a good representation of what the company is thinking about.
WD also asserts that their prototype uses standard AHCI drivers, for OS compatibility.
If you want to see this product in action, then -- well -- you kind-of need to be at Computex. At some point, you might be able to see it in your own PC. When? How much? No pricing and availability, again, because it is a tech demo.
Introduction, Specifications and Packaging
Intel has a nasty habit of releasing disruptive technology, especially in the area of computer storage. Among the first of those releases was the X25-M, which was groundbreaking to say the least. At a time where most other SATA SSDs were just stopgap attempts to graft flash memory to a different interface, Intel's SATA SSD was really the first true performer.
With performance in the bag, Intel shifted their attention to reducing the cost of their products. The next few generations of the Intel line was coupled with leadership in die shrinks. This all came together in the form of SSD releases of increasingly reduced cost. Sure the enterprise parts retained a premium, but the consumer parts generally remained competitive.
Now Intel appears to have once again shifted their attention to performance, and we know it has been in the works for a while now. With the SATA bottleneck becoming increasingly apparent, big changes needed to me made. First, SATA, while fine for relatively high latency HDD's, was just never meant for SSD speeds. As SSD performance increased, the latencies involved with the interface overhead (translating memory-based addresses into ATA style commands) becomes more and more of a burden.
The solution is to not only transition to PCIe, but to do so using a completely new software and driver interface, called NVM Express. NVMe has been in the works for a while, and offers some incredible benefits in that it essentially brings the flash memory closer to the CPU. The protocol was engineered for the purpose of accessing flash memory as storage, and doing so as fast and with the least latency as possible. We hadn't seen any true NVMe products hit the market, until today, that is:
Behold the Intel SSD DC P3700!

Tagged: SATA Express, pcie, asus, ssd, Z97-Deluxe
KitGuru had a chance to test the ASUS Z97-Deluxe with a Concept Edition SATA Express SSD from ASUS to see what happens when you can feed the data from an SSD across two SATA ports, giving it the bandwidth of two PCIe lanes. That should allow a theoretical 10Gbps bandwidth as PCIe 3.0 lanes are still being held in reserve as there are not that many available on an LGA1150 board but as KitGuru points out "leaked information suggest (we still cannot confirm anything) that M.2 support will be native to the ‘future Intel chipset’." Check out their review and be prepared to be amazed that the speed of 728MBps was lower than expected.
"We revisit the SATA Express interface to obtain a more up-to-date look at what the next generation of SATA connections is capable of. Our tools for the job; a retail Asus motherboard set to release soon, and a concept version of Asus’ Hyper Express enclosure, internally powered by solid state storage."

While many of us are perfectly content with the quality of the audio output from the motherboards onboard audio codec there are others who because of incompatibilities (looking at you PunkBuster) or who are gifted with good ears who are still in the market for a discrete sound card. A forum member recently pointed out that the sound card on the Hardware Leaderboard was so old it didn't ship with Win7 drivers so ASUS's timing on releasing three new sound cards couldn't have come at a better time. The ASUS Xonar DGX 5.1 is the lowest cost of the three cards at $40, though currently on NewEgg the Xonar DSX 7.1 card is only $37 after MIR. Finally is the Republic of Gamers Xonar Phoebus at $200, with a long list of features for those who want the best. Drop by [H]ard|OCP to see how these three cards do when put to the test.
"Asus recently released it's new flagship gaming sound card, the ROG Xonar Phoebus, as well as updated PCI-Express versions of its popular DG and DS sound cards. All three of these cards feature quality components for products in their respective price ranges. Today, we will tell you exactly what each card may bring to your PC audio experience."

Just over a month back we took a look at the Intel SSD 910 Series PCIe SSD. While the specs and performance were excellent, there were some factors preventing use in workstation systems - namely the prohibitive cost and lack of a Boot ROM. With that, it seems SanDisk has made an attempt to answer that call. Today at Computex they announced a new PCIe Enterprise SSD, the PCIe Lightning:
This is a much simpler layout, with flash right alongside the controller - an option not possible with the multi-PCB Intel 910 Series as it contained much more flash on its daughter boards. With this simpler layout comes lower cost but unfortunately lower maximum capacities. Less complexity also means lower maximum specs, but they still look quite good given the price point this card will be filling:
- Price: $1350 (200GB) / $2350 (400GB)
- 4k 70/30 R/W split: 23,000 IOPS
- Sequential Throughput: 425 MB/sec
- Warranty: 5 Year
- Endurance: 10 full-drive writes per day for warranty duration
I'm glad to see some good PCIe SSD competition cropping up - especially the bootable kind.
Background and Internals
A little over two weeks back, Intel briefed me on their new SSD 910 Series PCIe SSD. Since that day I've been patiently awaiting its arrival, which happened just a few short hours ago. I've burned the midnight oil for the sake of getting some greater details out there. Before we get into the goods, here's a quick recap of the specs for the 800 (or 400) GB model:
- PCIe 2.0 x8 LSI Falcon 2008 SAS HBA driving 4 (or 2) Hitachi Ultrastar SAS controllers, each in turn driving 200GB of IMFT 25nm High Endurance Technology flash memory, all on a triple stacked half-height PCB.
- 400GB model yields (r/w) 1GB/s / 750MB/s sequential and 90,000 / 38,000 4k IOPS.
- 800GB model yields (r/w) 2GB/s / 1GB/s sequential and 180,000 / 75,000 4k IOPS.
- 800GB 'performance mode' (r/w) 2GB/s / 1.5GB/s sequential and 180,000 / 75,000 4k IOPS.
"Performance Mode" is a feature that can be enabled through the Intel Data Center Tool Software. This feature is only possible on the 800GB model, but not for the reason you might think. The 400GB model is *always* in Performance Mode, since it can go full speed without drawing greater than the standard PCIe 25W power specification. The 800GB model has twice the components to drive yet it stays below the 25W limit so long as it is in its Default Mode. Switching the 800GB model to Performance Mode increases that draw to 38W (the initial press briefing stated 28W, which appears to have been a typo). Note that this increased draw is only seen during writes.
Ok, now into the goodies:

California based company mLogic LLC debuted a new “mLink” Thunderbolt enclosure at the NAB 2012 show that will allow users to connect PCI-E based cards to computers using Thunderbolt connections. Unfortunately, enthusiasts wishing to slap a graphics card into the enclosure are out of luck. The incompatibility is due to graphics cards not having Thunderbolt aware drivers and may be something that is rectified in the future but currently not an option.
Right now, there are only a few storage devices and networking NICs that are compatible with the mLink enclosure including Apricorn and OWC PCI-E SSDs, Atto Technology’s Fiber Channel network cards, and Atto Technology’s SAS RAID controller cards. (The full list of compatible devices is located here.) Not terribly exciting, but some users will find it very useful. The design is very streamlined and sleek, though its worth mentioning that it comes at a cost of $400 USD.
Enthusiasts wanting to add more graphics horsepower to their notebooks will have to look elsewhere, but for users that need super fast storage in a sleek industrial design enclosure it is an interesting option. The price will be something that turns many people off of it, however. It is slated to release in June with pre-orders being accepted now. More information along with photos of the device is available here.
It sure looks nice, but is this something people will actually use? Let us know in the comments!
