The traditional thoughts on ZFS are to have arrays which are a power-of-2 when it comes to number of disks. That means 2, 4, 8, etc. But for raidz1, that would be 3, 5, 9.

Ever wondered if software RAID is faster/slower than hardware RAID? I’m going to find out. It’s not complete, and I just thought of an extension, but What RAID-1 setup should I use for FreeBSD 6.0? is a work in progress. The extention I mention is to compare i386 against amd64.
