Of course when it's time to upgrade you can always just call sun and get a Thumper on a "Try before you Buy" - and use it as a temporary storage space for your files while you re-do your raidz/raidz2 virtual device from scratch with an additional disk. zfs send/zfs recieve here I come.....
Not sure if Sun would condone this, but how else is a SOHO user going to back up 3TB of data? Here's my story. I currently have 1.5TB of data scattered throughout my network. Some machines have raid, but a large portion of the data is sitting on standard drives, waiting for them to fail. To help ensure that I don't lose data, I'm building a NAS. My NAS chassis is a Supermicro SC933T with 15 hot swap SATA spaces. If I use ZFS as it currently exists, I will start off with a 6+2 raidz2 of 500GB drives. I will losing 1TB to parity, but that's a worthwhile investment. If I add a 5+2 raidz2 of 500GB drives, I'm losing another 1TB to parity, which doesn't make me particularly happy I'm comfortable with having 2 parity drives for 12 disks, plus another disk for hot spare. Combine that with regular data scrubbing and I wouldn't be worried about data loss. But without raidz/raidz2 expansion, or a "loaner" storage system, there's no way to get there short of starting out with all 15 drives.
