Which one is faster:

- Two separate RAID 0 arrays with 4 physical discs (4x160 gb)
- One RAID 0 array with 2 discs and two partitions (2x320 gb)

Assuming that the end result from both is C: 320 GB and D: 320 GB. (and that all the harddrives have the same specs...)

4 drives in one RAID-0 will more risky to data lost because of one drive failure.
Why you want absolutely 2 drive letter? May be you can look at RAID-5?
What will be your backup procedure?

I would choose two RAID-0 and use the second one as a backup (if you don't have an on-line backup or external backup).

If speed is only matter, I would try both configuration and do benchmark. I would also look at Raptor 150.
