The Sandberg Multi Hard Disk Box 2.5” lets you use a 2.5” IDE or SATA hard disk as a portable external hard disk. The box connects to your computer either via USB 2.0 or eSATA, giving you speeds of up to 3 Gb per second (IDE hard disks cannot, however, be connected with eSATA). If your computer doesn’t already have eSATA, you can use the adapter bracket supplied to convert an internal SATA port to an eSATA port.
