I agree that 3ware controllers are good hardware and worth the money,
but I suspect you are comparing the time of swapping an internal
drive vs. a swappable cage here. It's not that hard to type
an fdisk command followed by an mdadm --add command. Many/most
IDE controllers do lock up when one of the drives fails with certain
failure modes - this can be a problem especially if your boot drive
is there. Scsi tends to fail more gracefully.
