Here's an alternative I'm going to buy for around £300 all in that provides a solid state DDR drive that plugs in via SATA.

Here is the actual manufacturer of those hyperos cards. Acard's ANS-9010 Ram Drive. If you are running a server and want even more performance, I like this card that plugs into a pci express slot Fusion-io's iodrive

Of course the iodrive costs a couple thousand for a some 80GB drive, but it's spec'd to be equivalent in transfer, write and seek time to a bunch of raid SSD's. These are just NAND clusters that beat the speed by acting like a large RAID of small flash memory. It uses software/hardware to overcome some limitation of the number of read/write of NAND and memory keeping the data safe. As it ages, it gets less storage GBs but stay just as fast. It utilizes the bandwidth of the pci-e (x4 iirc).

The Acard ans-9010 ram drive (aka hyperos card) also do raid on a single card which does help a bit when trying to saturate some SATA bandwidth. Check out this comparison for the Acard at the tech report. The input/output benchmarks put a bunch of the other disks down. But, on efficiency, X-25m SSD's kicked the acard's ass because it doesn't use RAM meaning lower consumption/heat and does webserver expectionally well.

Intel X-25m SSD's in raid would prove to be a good combination that won't break the bank as much the more exotic options. After getting a bit intoxicated with the idea of the iodrive and acard ans-9010, it turns out what I want isn't exactly what I need, at least not at that price and definately not for my gaming. All SSDs have the advantage of seek times. The only disadvantage I see with X-25m's, as with other similar flash SSDs are the write times. Reads are hardly ever the problem especially with these built for performance disks.

The guy who does budget will kill you after seeing how much your 6TB Samsung SSD Awesomeness cost to just play with user-end desktop apps. Save the big bucks for the servers that bring in the moolah and server the clients, and even then we can't all prematurely splurge on sexy new toys.
