I think the people that will really benefit from this product are computer support staff and your computer enthusiast with multiple drives. I would be bit wary about using the enclosure to permanently hold a drive for use as an external. The enclosure does leave the drives exposed to the elements (dropped soda, messy kids, etc). In a computer repair environment this shouldn’t be much of an issue as they should already have safeguards in place for those sorts of things. I’ve worked in both a computer repair shop and in large scale IT. From my experience, it would be super convenient to have an enclosure that I can slap two drives into and do a 1-to-1 copy of them without having to open up cases or fidget with screws.
Thermaltake has done a nice job with their redesign of the BlacX line. It’s not often that a company can take an innovative product and improve upon it successfully. The quick release buttons make it easy to swap out drives. The build feels sturdy. This docking station should be a tool in your computer repairing repertoire.
