[nycbug-talk] Rackmount eSATA Enclosures

Hi Mark,

I've used the Sans Digital enclosures, but not rackmount stuff.

I've used the non-raid variants of this at home,


This stuff looks kindof cheap, this rackmount box could be awesome- or could end up being terrible waste of time.

The Sans-Digital stuff with various hardware RAID options are absolute trash, friends have bought those with terrible results- (even when not using the HW raid features).

The stuff I've used, (over USB- with FreeBSD and MacOSX), has been as good as USB is… slow and adequately reliable for Tb+ green/slow/cheap drives.

I've even toyed/tested them with ZFS volumes, however, the speed of the single bus from the device makes them terrible for any actual ZRAID pool use- (unless I guess you split spools across multiple containers, which gets silly for me to live with- e.g. "which drive is in which sled?" hyjinks).
A single slow drive as a ZFS pool works just great, (with all the other ZFS features), and for 2-3tb slow/cheap drives, it's far more pleasant to live with than UFS- (formatting takes *forever* with UFS here, for starters...)

I really love their little enclosures as simple, slow cheap SATA drive sleds.

Hope that helps-
