RAID-0 FFS?
Please, there is only one application for a RAID-0 box and that is a temporary store for massive video files, etc, while you work with them. You should make that very clear in any proposed test. If you value your data then RAID-0 has no place at all!
Also worth pointing out for the more technical commmentards to consider, you can get an HP ProLiant Gen8 G1610T micro server for under £200 and slap FreeNAS on it, and if you want some more performance also stick in a small SSD for the ZFS Intent Log to give you a reasonable comprimise in performance vs. storage cost.
