Gigabyte i-ram II uses DDR2 and SATA300
Since DDR2 is getting so damn cheap they decided to use DDR2 instead of DDR1 for the next revision. Upgrading the battery capacity and speed to SATA300, increase ram slots from 4 to 8 AND also abandoning the PCI design and move to 5.25" Bay
That would be freaking awesome, get 4 i-ramII with a 1GB stick on each, you get 4GB of insane fast storage. (SATA300 RAID0 = 1.2GB/s)
with STR equal to 32 HDDs in RAID0, and also random seek time in nanoseconds, it'll practically eliminate HDD from bottleneck.
