I first read that "2.8 GB" as 2.8 TB and was utterly confused! You'd save a bunch of energy if you only powered up venti disks once @ 4AM for a few minutes (and on demand when you look at /n/dump). Though venti might have fits! And the disks might too! So may be this calls for a two level venti? First to an SSD RAID and a much less frequent venti/copy to hard disks. venti doesn't have a "scrub" command, does it? zfs scrub was instrumental in warning me that I needed new disks.
