Hard disk drive enclosures are cases for you to install a hard disk drive outside the computer, being a terrific way to carry a huge amount of data around, for backing up data, for storing and carrying files from home to the office and vice-versa, for storing and carrying videos, etc. The main problem with external hard drives is speed, because most of them are based on the USB 2.0 port, which is limited to 60 MB/s (480 Mbps). Max 4 Active Cooling from Thermaltake, however, has also an eSATA port, which is the best way to connect an external hard drive, as this interface allows the hard disk drive to be accessed at the same speed as it were installed inside the PC. Let's take a detailed look on this Thermaltake enclosure, including its performance.
