I've had no problems hot-swapping SATA drives on 3Ware 8006-2LP
controllers using Vantec MRK-200ST-BK drive bays and caddys. It must
be said this is just disks in JBOD mode though, no underlying hardware
or overlying software RAID.
You can "park" the disks in 3warecli, swap them out and then rescan
for new disks[1].
The drive caddys are a bit "boy-racer" and not as solid as good SCA
caddys from say Compaq or Dell but they do the job.
Will.
