Hard Drive Raid Question

Is it possible to run two different capacity hard drives in RAID 0 (one is 320GB and the other is 250GB).

Thanks :)

It would probably work (depending on the controller) but not recommended. The RAID array could only use 250 GB of the larger drive. Using that space for other purposes could compromise the performance you are trying to gain.

In most cases RAID 0 is more trouble than it is worth. The benchmarks are impressive but real world performance is more modest. A big downside (among others) is that if one drive fails you loose everything. Backups are always necessary but even more important with RAID 0.
