FWIW, I just got my hands on one of the 8-stick version 5.25" RAM drives from Acard today. Faster than a cheetah chasin' down a fat kid. Just about saturated my GbE network at between 65-90+ MB/sec transfer of a 10GB dv file between the Acard drive and a 3Ware 9590SE RAID 6 array. HD Tune shows 160MB/sec sustained read. Granted, it's a synthetic, and I am running the SATA port as enhanced IDE, but this thing is just unreal. Blows away the i-RAM's in terms of convenience and expansion (will handle up to 8Gb sticks of DDR2 RAM according to Acard). Have (8) 2Gb sticks in mine. Forget Gigabyte's vaporware i-Box. If you have been waiting for a RAM drive with size, this is it.
