RAID0 isn't reliable at all because there's no redundancy... a single failure will render the array unusable. If it's just used as capture+scratch space then this isn't such an issue, although the PC will not be able to boot with a failed array.

If it's used for transient data then perhaps consider the OS+perm data on a single drive, then a 3 drive RAID0 array.

BTW, 4 x 250GB on RAID5 is actually 750GB useable... you lose 250Gb to redundancy parity.
