R-Driver III USB 2.0 to SATA IDE Cable

I find this cable very useful to transfer data from one computer to another, backup data to CD/DVD or install operating system or software if your computer does not have any optical drive. It comes complete with power adaptor, SATA data/power cable and can be used as follows:

1. Connect laptop 2.5" harddisk (IDE/SATA) to any computer via USB without power adaptor
   
2. Connect desktop harddisk (IDE/SATA) to any computer via USB with power adaptor
3. Connect CD-ROM/CD-RW/DVD-ROM/DVD-RW (IDE/SATA) to any computer with power adaptor

This is more cost effective than buying USB casings to house the external devices. But, if you require an external harddisk permanently for storage, it is better to house it in a USB case to minimise dust or damage.
