SATA may be an interface that supports hot swap, but in reality, how often is it truly taken advantage of and used for the purpose of hot swapping? More than often, it's no more than just an array of disks residing inside our computers that ends up rarely moved. For an external interface, eSATA is nice and all for its performance, but to an extent that's really an extension of an internal storage medium to external hard drives -- hot swap is necessary as what's that made USB so popular, but it doesn't really solve the problem of having a need to go through a bunch of internal SATA hard drives quickly. For example, some users need it for testing hard drives, while others want to quickly pull some data off a drive without installing it in another computer. As far as I'm concerned, there's one product in the market that has gained immense popularity and tons of internet hype that allows you to quickly swap internal SATA hard drives without ripping anything apart to get the job done. And that's the Thermaltake BlacX, an HDD docking station. Let's see how it gets its job done, and to what extent it has done well.
