SimpleTech, recently acquired by Hitachi, makes a solid, quiet, easy to use hard drive. That pretty much sums it up, but I’ll go into some detail. Most hard drives are easy to use with Macs, but the software included with this drive is fairly simple and works really well.
The [re]drive is quiet and runs cool due to the bamboo and recycled aluminum chassis. The packaging is minimal and the physical hard drive under the casing is energy efficient. Even the power adapter is Energy Star approved.
This drive is pretty damn awesome and I suggest you check it out.
