Review on Bipra S2 NTFS Portable External by Chris Russell

This arrived quickly and worked great on my XP machine. I'll probably buy another one and swap it out. It includes disk backup software. Only one USB port is required, although there is a second connector on the Y-cable. Although there is no compatibility information in the Revain list, the system requirements are listed in the box: USB 2.0 port available - PC, Laptop or Mac. System Windows 98SE/ME/2000/XP/Vista/&8, Mac OS X 8.6 and above.
