Well, I must say I quite like the Thermaltake BlacX Hard Drive Docking Station. Transfer speeds were the same or better than the two traditional style enclosures that it was compared to. The ability to hot swap not only 3.5" hard drives, but 2.5" notebook drives as well, makes this unit a must-have for a computer enthusiast. Most enclosures are built for a certain size drive and take some work swapping them out, but with the Thermaltake BlacX, you just push the eject button and place a new drive into the docking station. This is especially good for transferring files from an old drive to an upgraded one with ease. One thing I liked is the fact that there are no fans, meaning it is very quiet when in use.
