The USB to eSATA Adapter lets you convert any standard SATA hard disk (i.e. most modern high capacity drives) into an external USB drive. Just plug this doohickey into the USB port on your laptop and bingo, you can hook up any standard hard drive as an external unit. I suggest you pop the drive into a shoe box or something first though, just to keep it nice and cosy, eh? $25.00 with add-on power cable for the drive.
This USB to eSATA adapter turns any SATA or eSATA mass storage device into a convenient external USB 2.0 High-Speed drive. This adapter supports 2.5″ and 3.5″ SATA hard drives, SATA CD/DVD drives and eSATA drive enclosure. It is a great test bench device perfect for technicians or anyone needing to copy or offload files from one hard drive to another.
