Aren't most/all SATA controllers hot-swap by now? Check http://
linux-ata.org/driver-status.html before you buy and you should be in
good shape. I thought it was part of the SATA spec and the only
controllers that didn't support it was "bridged" PATA controllers.
Typically for MogileFS devices it's a waste of money buying a fancy
SATA controller. (If you do want one, then the new 3Ware ones are
pretty good - the ones from 3-4 years ago not so much).
