RamSan-440  (Source: Texas Memory)
Massive 4U SSD can sustain 600,000 IOPS

Solid state drives (SSDs) are being eyed as the future of enterprise data storage for the improvements in speed, reliability and energy savings they offer. SSDs for consumers are small devices very similar in size and shape to the traditional hard drive used in computer systems.

The SSD in an enterprise environment often takes on a different form factor though and the latest of these enterprise SSDs is from Texas Memory. Texas Memory says that its RamSan-440 can sustain a record setting 600,000 IOPS (input/outputs per second) and can be had with capacities of 256GB and 512GB.

The available storage space is a record for RAM-based SSDs. EWeek reports that the RamSan-440 is also the first SSD to use NAND flash modules in a RAID configuration for data backup. The SSD also uses proprietary technology from Texas Memory called IO2 (Instant-On Input-Output) that improves availability by making data requested from users or applications available instantly when the system is on.

The RamSan-440 uses DDR2 RAM reports eWeek and can sustain 4Gbps random read and write speed with a latency of under 15 ms. The device is in a 4U rack mount chassis and can be attached via SAN or directly attached via up to eight 4Gbps Fibre Channel ports.

Data backup is accomplished using RAID protected flash memory modules. Backup is done continuously to the internal flash modules with little impact on system performance. Pricing information is unknown, but considering that a ”cheap” consumer SSD with 128GB is right at $500, the RamSan-440 will cost a pretty penny.

Should Clarify

This drive is an SSD, but its a DRAM-based hybrid and shouldn't be directly compared to the compact 2.5-3.5" NAND flash SSDs that are what most people think of when talking about SSD. The RamSan uses DDR2 DRAM and while 256 to 512GB capacities are impressive, that's also why the form factor is so large. They use NAND flash as backup, but its also much slower than DRAM. I've actually been hoping an updated DDR2 i-RAM was released given the dirt-cheap prices of DDR2. This is a bit more than I expected though.

Same here.

Same here. Hoping to see an 8 slot (doublesided) i-Ram for DDR2 @ SATA300. Not holding my breath though.

Interesting.. i posted this link a month ago, to Daily Tech, and the guy is posting about it like it is something new.. NICE...
This Texas MemSystem, SAN is the bomb. A game server, added 1 to their server farm, and saw instantaneous results, from the players themselves.
My previous company, we evaluated one of these, back in 2005. WAY back when the 96GB model, cost 120k. Yah it was crazy price, until we started running reports, that on 8x73gb 15k raid 10, took 4 hours. a Fibre San with 16 drives raid 10, 15k drives took 2 hours, and this Texas MEM san, took of all 2minutes. IF that. We started it, grabed a coke, and it was done. Re-Ran it, and it was almost instantaneous so hard to judge.

Ran a Report that normally takes 45min on the fastest server we had, fastest workstation, GB everything. We ran that report again, BOOM less than 20sec. The IO is just insane.. Granted the cost is up there. But with 1000 users hitting the same database, over and over.. well worth the investment. Virtual servers on this, was crazy.. Almost a instant boot, with win2k3. granted , 3 years, ago, the raw storage would not work.. but now, with TEX mem systems, you can get well above 1tb.. Well worth it, if performance is truly needed..

Why so serious

Exactly. The writer of this article needs to make it more explicit that this is NOT the common type of NAND flash-based SSDs that most people think of when hearing the term. This is completely different, basically an external box of RAM setup to be recognized as a hard drive.
