I'm in the process of replacing al the old drives but it seems problematic.
Scanning and resilvering is incredibly slow with intermittent slow downs to zero.
I'm thinking it's been a combination of bad drives and bad controllers. (the built in ones on the motherboard that is many years old)
My plan is to use this box as a FreeNAS server with a proper controller card.
I will build a new hackintosh and only have a small SSD mirror for local media storage like Pictures, iTunes, etc. while storing the rest and making backups to the FreeNAS.
I'd love to set up an SSD mirror on the new machine for booting but I'll wait until I feel like it's mature and stable enough.
I forgot to ask how long you have been using zfs on osx. Were you using raid5 before? Would you ever go back to perhaps an HFS RAID1, if only because you knew there were more recovery tools? I'm planning to do only pairs of mirrored drives so I don't get too locked into a certain size of drive.
