There are solid state drives, connected via SATA-II, that claim to be 
able to read 285MByte/second, but even with one of those it's not sure 
if the data rate is enough. With IDE drives, a RAID-0 with two discs has 
a theoretical maximum data rate of 266MByte/second, that isn't plenty 
either. So I would say, to achieve such a data rate a RAID of SATA-II 
solid state disks would be neccessary.

The best choice for playing uncompressed HD video will be a ramdisk, I
