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.

Sandisk had a booth with a large array of small nand flash storage devices, though most of it appeared to be SD, CF, or for embedded mobile applications:
One of the more interesting pieces was a 64GB e.MMC nand flash part that fit *within* the dimensions of a penny! This is not a plug-in module - it's the type that would be soldered onto the mainboard of a cell phone or other small mobile device:
While the booth was generally light on SSD's, there were a couple on display, namely the U100, in both 7mm (left) and 9.5mm (right) form factors:
The U100 is also available in even smaller form factor. We're currently taking a look at an Ultrabook equipped with the same Sandisk U100 SSD - mounted to an even smaller PCB.
PQI has been a favorite of mine for years. They were among the first to make a really tiny thumb drive, and I'm glad to see they continue to make a versatile line of products:
A little known fact is that PQI also has a line of SATA SSD's:
The S525 Series (also available as the S518 - 1.8" form factor), is a bit long in the tooth and uses a dated JMicron controller, but PQI made the extra effort to include the optional USB 2.0 interface that most other manufacturers chose to omit.
More to follow
I've still got some pics to sift through, so stay tuned for more CES Storage goodies!

SanDisk is releasing a line of SSDs, called the Ultra series. They are not aimed at the high end market, they use the older SATA 2 interface and claim sequential transfer speeds of 280MB/s read and 270MB/s write. The prices should range from $130 for the 60GB product to $450 for the 240GB model, which puts them about middle of the road for pricing. They also list expected lifetime in terms of the amount of data written to them; 40TB of data written for the 60GB up to 120TB of total data written to the 240GB. The Register covered the release here.
"SanDisk has a new Ultra line, a cruise flash missile aimed at taking out PC and notebook hard drives and replacing them with much faster SanDisk SSDs.
These are 2.5-inch format, 2-bit multi-level cell flash drives, coming in 60, 120 and 240GB capacity points. The Ultra brand is used by SanDisk for consumer flash products such as SDHC cards, and now a trio of SSDs will be sold under the Ultra name."
