Flash storage company Sandisk has recently jumped into the world of enterprise PCI-E caching SSDs – what they are calling Solid State Accelerators. Currently, they are offering a 200GB and 400GB model under the company’s Lightning PCIe series. The SSDs feature a proprietary Sandisk controller driving 24nm SLC NAND flash, a PCI-E 2.0 x4 interface, and maximum power draw of 15 watts.
The Lightning Accelerators use the NAND flash for Sandisk’s own foundry and offer a large performance boost for servers and workstations over hard drives and SATA SSDs. It is capable of 410 MB/s sequential reads or 110,000 IOPS. Further, when using 4KB and 8KB blocks, the drives can reach 23,000 and 17,000 read/write IOPS respectively. Other specifications include an average response time of 245 microseconds, and less than 30 millisecond maximum response times. The Solid State Accelerators also feature sustained read and write latencies as low as 50 microseconds.
Sandisk has built the drives so that they can be configured as boot drives, storage drives, or caching drives. The company supports up to 5 drives in a single system, for a maximum of 2TB of flash storage. In addition, Sandisk is offering up its Flashsoft software that allows the Lightning Accelerators to be used as caching drives on Windows-based systems. Unfortunately, that is an additional cost which is not included in the already pricey SSDs (good thing for corporate expense accounts!).
Speaking of pricing, the 200GB LP206M has an MSRP of $1,350 while the 400GB LP406M has an MSRP of $2,350. Both cards have five year warranties and a MTBF rating of 2 million hours. You can find more information on the Sandisk Website.
It will be interesting to see how this Sandisk accelerator stacks up to the likes of the Intel 910 and FusioIO drives! The FusionIO FX, for example, gives you 420GB of QDP MLC NAND for $2,495, which works out such that Sandisk has a slightly lower cost-per-gigabyte value and SLC flash. We will have to wait for some independant reviews to say which drive is actually faster, however.

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.

Enterprise level storage has vastly different priorities than consumer grade storage as data that is lost is of a different level than lost pictures and home movie. As precious as those memories are it is unlikely that family members will sue you or disown you because you lost their data, internal and external customers on the other hand are very likely to. This places a large priority on reliability which must be considered even before the cost savings are considered. For companies with large databases and numerous users connecting to them concurrently there is a huge time savings possible from introducing an SSD to the front end, but only if it can be guaranteed to be available and not down.
The SSD Review takes a look at Samsung's enterprise class SSD, the SM825 which has 400GB of eMLC flash storage which is rated at 7000TBW (terabytes written) before failure; consumer models are usually 60TBW. When the SSD Review cracked the case and did some addition, they spotted 112GB being used for over-provisioning as well as four impressively sized capacitors for protection against power outages. Check out the full review to see how it performs.
"In reviewing the Samsung SSD SM825 Data Center Edition 400GB eMLC solid state drive, we understand that we have wandered off the beaten path of normal consumer reviews but there are some things in this SSD that will just grab your attention. Although it’s interesting to see that Samsung has chosen its own premium eMLC NAND flash memory in the SM825, we believe that it is the total write endurance that truly stands out in this enterprise class SSD."

Hitachi recently released a new enterprise class SSD based on Intel's 25nm MLC flash. Dubbed the Hitachi SSD400M, the new solid state drive is aimed at Enterprise users and Cloud data centers. It comes in the standard 2.5" form factor, features a SAS 6Gb/s interface, and will be available in 200GB and 400GB capacities.
As an enterprise drive, the Hitachi SSD400M supports end to end data protection, error correction, error handling and self encryption on certain models compliant with the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption specification. Further showing it's intended usage as an Enterprise drive, the 25nm MLC based drive is rated for 7.3 Petabyte lifetime write, which Hitachi says amounts to 10 full drive writes per day for five years. Coincidentally, the warranty of the drive is a five year limited warranty or until the drive exceeds the maximum rated number of petabyte writes per capacity. Hitachi states that they expect a .44 annual failure rate and have projected a 2 million hour MTBF.
Performance of the drive is much better than that of the previously reported Intel drive, as it delivers 495MB/s sequential reads and 385MB/s sequential writes. The SSD is further rated at 56,000 read IOPS and 24,000 write IOPS.
The SSD400M has already shipped to various OEMs and will be available soon. More information on the new SSD can be found here.

For enterprise users looking to introduce Firefox to their business: you may wish to reconsider. Businesses are notorious for being substantially behind in version numbers, occasionally (or a lot) trading even security for compatibility. Mozilla had a staggered release schedule: a minor version number was little more than a security update; a major version number was a fairly-large overhaul. Enterprise users were able to upgrade minor version numbers and be reasonably assured that compatibility would be maintained. There were no such assurances for a major version number, thus requiring rigorous testing before applying. Mozilla has ended their policy of supporting back versions with security updates and are also moving between full versions much more rapidly, causing dissension amongst enterprise users.
Moving the world forward, not backwards, and always twirling towards freedom.
Ed Bott took the opportunity to prod Mozilla during his Thursday evening column. He contends that shutting out enterprise will assist in the impending implosion of Firefox and allow Microsoft and Google to pick up the pieces. I seriously disagree with that statement and applaud Mozilla for staying focused on their goal. True, Mozilla will be vastly less attractive to the enterprise; however, if Microsoft did not have Windows and Office to push with Internet Explorer, would search ad revenue and donations cover the long-term development cost incurred supporting enterprise users? And really, I would have thought Ed Bott of all people (ok, except maybe Paul Thurrott) would respect a company that can make a decision like Mozilla just did and stick by it after covering Microsoft for so long.

Intel is currently in the process of releasing their 2011 lineup of solid state hard drives. A lot of news and products came out regarding their consumer 300-series and enthusiast 500-series line however it has been pretty silent regarding their enterprise 700-series products. That has changed recently with the release of specifications as a result of Anandtech’s coverage of the German hardware website ComputerBase.de.
And how does it compare to OCZ?
Intel will be releasing two enterprise SSDs: the SATA 3 Gbps based 710 SSD codename Lyndonville and the PCI express 2.0 based 720 SSD codename Ramsdale. The SATA based 710 will feature 25nm MLC-HET flash at capacities of 100, 200, and 300 GB. The 710 will have read and write speeds of 270/210 MB/s with 35,000/3300 read and write IOPS at 4KB and a 64MB cache. The PCIe based 720 will feature 34nm SLC flash at capacities of 200 and 400 GB. The 720 will be substantially faster than the 710 with read and write speeds of 2200/1800 MB/s with 180,000/56,000 read and write IOPS at 4KB and a 512MB cache. On the security front the 710 will be encrypted with 128 bit AES encryption where the 720 will be encrypted with 256 bit AES.
While there has been no hint toward pricing of these drives Intel is still expected to make a second quarter release date for their SATA based 710 SSD. If you are looking for a PCI express SSD you will need to be a bit more patient as they are still expected to be released in the fourth quarter. It will be interesting to see how the Intel vs OCZ fight will play out in 2012 for dominance in the PCIe-based SSD space.
