OpenZFS on OS X

Hi

I am considering building a backup RaidZ2 from 6-8 8TB Seagate Archive HDDs. I have read the Storage Review article that demonstrates the performance issues and discusses the use cases, so I am comfortable with that.

Has anyone else experimented with these drives for backup or archiving? Besides setting ashift=12, I can't think of any other special concerns, other than performance issues.

The write can be very slow, but if you indeed use them for "archive" style, ie, write the once, but read many times, you will be fine. Mostly, ZFS is one of very few, that can actually handle archive disks.

I can't imagine performance could be any worse than my experimental backup RaidZ3 8x3TB with dedup on at 99.5% capacity!
