Comment Macs don't need to "hold" multiple drives (Score 2) 224
Don't forget their cheapest desktop that can hold two hard drives and an optical drive is the Mac Pro.
The operative word being "holds". With USB and Thunderbolt, there is *zero* reason to have more than one hard drive slot inside a Mac.
The next Mac Pro doesn't have *any* internal drive bays. None of the creative pros, whom the machines are targeted at, are complaining. They're happily going to connect multi-terabyte RAID arrays to it via any of its six thunderbolt 2 ports, each of which offers more bandwidth than a multilane 6Gbps SAS port.
