The best thing you can do is reduce the system volume down to around 250GB, and mirror it, then the remainder should be for data, again mirrored. Striping (Raid 0 provides no redundancy).I understand that striping provides no redundancy. However, my primary goal here is performance, not redundancy. We make regular backups, and the loss of a few hours while restoring in the event of a hard drive failure would not be catastrophic. It is more important that our users get the best possible performance -- within our hardware limitations, of course. It was based on that I was going in the striping direction, because I was under the impression that striping does provide improved performance over mirroring, where each piece of data must be written twice.
If redundancy is not an issue for you then go for RAID0 (stripping) as it will give you double performance to compare RAID1 or single HDD. In your case nothing can give you better performance than RAID0.Thanks! I am definitely going to look into some hardware upgrades later in the year, but for now I have to make do with what we have. That's why I was thinking RAID 0.

Have you checked the bios menu of the server to see if there is a simple on-board raid controller, rather than using the Windows raid?
