Note that hooking this unit up to a Mac that does not have thunderbolt ports and buying a FireWire adapter to facilitate the hook Note that hooking this unit up to a Mac that does not have thunderbolt ports and buying a FireWire adapter to facilitate the hook up to your older Mac will not make the unit mount. Thunderbolt requires a protocol-specific instruction set to pre-exist on the Mac's CPU. Your older pre-thunderbolt Mac won't have that instruction set and so this drive will never work for you. Additionally, there are no Thunderbolt expansion cards (PCIe) to put into your old Mac to get it working because, again, the instruction set is not on the host CPU.
Options: ensure you buy an external unit like this that *has* FW800 ports so you can use it with your older Mac (or buy up to a new or newer Mac).

So far so good

Plus the fan in the old unit is annoying loud. I use the raid to backup my photographic files. WD was not my first choice of manufacturer, but this unit fit my needs at a reasonable price so I bit. It arrived about three weeks ago, and so far no problems. Hook up was uneventful, it works with my old Superduper, and both the initial backup and incremental backups have gone smoothly. The Thunderbolt connection seems fast but I have not bothered to measure the speed because it is not critical for my needs. The unit is very quiet. Initially I was concerned about the lack of an on off switch, but it is quiet enough that I don't feel the urge to switch it off between backups. It is bigger than my old raid, but not so big as to be a problem. Overall so far I am a happy camper. …
