Partitioning RAID Arrarys

I have partitioned RAID 0 into 2 before, and it worked fine. Partitioning RAID 1 should work, too. 4 partitions shouldn't be a problem. Try it. Just in case it doesn't work, the worst that can happen is that you have to re-partition it as 2 or 1 partitions.

RAID 0 is not supposed to give alot of performance boost for most applications. For some applications, the performance boost may be significant, like maybe digital video editing.

I can't find the original article, but I think Loyd Case from ExtremeTech once cited an article from Tom's Hardware that argued against significant improvement with R0.

I used to not care, tho', because I liked to eek out every little bit of performance with R0. If your data is important, tho', you may be better off with R1. Next computer I build will be R1, because I now have my own side-business so my data is more important.
