The main problem with those nice little appliances . . .
. . is when they fail. If you can get parts at all, they cost nearly as much as a new unit. If you buy a new box, the ROM based OS in the new one may not recognize the format on the old drives. This has happened to several of my clients.

Yes yes yes.
A friend experienced this recently and another friend experienced a drive failure and the mirrored second drive was hosed during the process... making the superblocks un readable.
I recently had to rip apart a failed buffalo.
The file system is XFS, and it was too trashed to get anything back.
This was from a mirrored pair.
It seemed the mirror was fine, until we called tech support.
X amount of time and tech support later, the mirror was blown away.
Ooops.
