in my case it takes 2+ days to resync the array before I can do any
performance testing with it. for some reason it's only doing the rebuild

and a dd to the array seems to be ~44M/sec, even during the rebuild)
With performance like that, it sounds like you're saturating a bus
somewhere along the line. If you're using scsi, for instance, it's very
easy for a long chain of drives to overwhelm a channel. You might also
want to consider some other RAID layouts like 1+0 or 5+0 depending upon
your space vs. reliability needs.
