The host for this is up in the air. I'd hope I could use a Shuttle XPC.

It's an 8 drive USB enclosure. The total bandwidth to all 8 drives
would be 480Mbps, which is fine for me. I was hoping to do a RAID-Z or
RAID-Z2. I would have it export the drives as JBOD.

If I get my math right and understand ZFS... If I have 8x750 gig disks
using RAID-Z I will have 7x750 space available. This will provide
standard RAID-5 style redundancy. (6x750 for RAID-Z2)

My confusion is that I see a lot of people suggesting cutting it up
for mirrored RAID-Z setups. The main reason for this is performance
right? I am fine with standard USB 2.0 performance and RAID-5 (or 6)
functionality but with the added capability of data integrity
checking/self-healing/etc/etc. I don't need to build some crazy array.
Just something for SOHO use, sharing files over samba to a couple
Windows machines + a media player.

Side note: Is this right? "ditto" blocks are extra parity blocks
stored on the same disk (won't prevent total disk failures, but could
provide data recovery if enough parity is available)

Thanks,
mike
