similar concept, but there are some significant differences

the iRam was limited to 4G, used DDR ram, and used a PCI slot for power
(which can be in
short supply nowdays)

this new drive can go to 64G, uses DDR2 ram (cheaper than DDR nowdays),
gets powered like a normal SATA drive, can use two SATA channels (to be
able to get past the throughput limits of a single SATA interface), and
has a CF card slot to backup the data to if the system powers down.

plus the performance appears to be significantly better (even without
using the second SATA interface)
