Bazx and Maxi both have um....... you might want to mention them doing some testing or at least posting in the Storage area. Both of these folks are 3D/Cpu overclockers.

this has got to be the stupidest product ever... let me run my logic by you...
they design a solid-state drive with the intent of faster access times and higher read/write rates. then they hook it up to the pc through SATA...
the card is already PLUGGED INTO THE MOBO! Holy cow, why not just use the PCI bus?? idiots... the only advantage I can see from this is the access times- otherwise for the money you can build a cheap array that will perform the same or better...
check out: ddrdrive.com
Ive been waiting on it to come out for months. It is basically the same thing, but it uses the PCI bus instead of the SATA bus.

@adamwinn.. yes, but can you use the ddrdrive as a boot drive?
but the bandwith of the PCI bus is 133 MB/s , SATA is 187 MB/s.. were is the bottleneck?

...and can you run two of them in raid0? Which leads me to my next question...
Who's gonna volonteer to send me two I-Ram's so I can bench them in raid? Anyone? Anyone? Bueller? Bueller?

The PCI bus has a bandwidth of 133MB/sec shared among all devices on it, and latencies that let the computer "lock onto" a device for a specific ammount of time, so the total bandwidth is even less than you'd expect. By comparison SATA is actually the faster bus (187MB/sec) and you don't have any weird latency issues to worry about. If you want to argue about putting it onto a PCI-Express lane, well, that'd seriously pump up the bandwidth. But then again, so would putting it onto SATA 2. 
Besides, bandwidth isn't the only important factor. SATA provides a ton more flexibility, which can be valuable. If 4GB is too small (or 187MB/sec too slow), you can always RAID them like any hard drive. Also, using the drive to boot to windows is possible since its just another drive as far as the BIOS is concerned. This also means there's no worrying about drivers and updates, since it doesn't need any more than what's needed for your SATA controler.
/me actually loves that they used the SATA bus instead of PCI or PCI-E
BTW, if you really want a drive that uses the PCI bus, check out the Rocket Drive. It's been around for a while, so no need for waiting. It uses SDR (not DDR) memory though, and is a wee bit expensive at $1,599.00 for the version pre-populated with 2GB ($2,999.00 for the 4GB, and they don't sell the bare card).

That seems like such little bandwidth for the supporting ram that it can use. It says it uses up to pc3200 which is 3.2GB/s or 6.4GB/s if it supports dual channel. Way too much for either pci or SATA. They should go with pc2100 or less. Other wise it is a waste of money.

8 x I-RAM's - 112 x 8 = $896
32 x 1GB DDR Sticks - 60 x 32 = $1920
1 x Areca ARC-1220 PCI-E = $560
TOTAL = $3376 for 32GB Hard Drive reading and write at 1GB/s ($105.50 per GB)

Totally sweet...
However, while this is great as an entusiast product, they need to use the same technology but open up a market for those without the budget to afford to use full on system ram as storage. Start production on very cheap RAM chips. It will be slower, say DDR66 speed. Offer 16GB/32GB/64GB+ of it built into a drive. PROFIT.
I'd buy it...

Sorry guys, I typod on my original post. The ddrdrive that I am waiting for uses PCI-E as AVRO pointed out.
Ive been incontact with the makers of the product and its going to be very, very exciting when it arrives.
