Try an article like this. They used a Gigabyte iRAM device,
and tested to see how much performance could be improved.
Now, compared to your RAID0 idea, the iRAM has close to
zero seek time. There may be another review or two around,
where someone used the iRAM in a RAID array, but the iRAM
doesn't work properly with hardware RAID cards (because
the SATA emulation isn't good enough). It does work with
some Southbridge RAID interfaces. Someone over on 2cpu.com
tested a handful of iRAMs, on some hardware RAID cards.

So a RAID0 made from hard drives, will give less of a
boost than the charts in that article, due to seek time
not changing. If the operation you're trying to speed
up, is dominated by head movement (seek), then RAID0
won't help with that. RAID0 is going to help a lot with
Photoshop read/write times, or scratch disk operation.
