Hard drive docking stations are external HDD devices that are designed to give you quick access to your stored data. The docking stations connect to your PC via a USB or SATA, the drive will then show as an external drive in your operating system and is used in the same way. Hard drive docking stations allow you to move files between your PC and the hard drive and archive and recover data. Some hard disk docking stations are available with two slots so you can test or benchmark multiple hard drives. HDD docking stations can speed up your computer and are more accessible and easier to upgrade than internal hard drives.
