Strengths

The DriveStation Duo is an external storage device with a difference. Its main selling point is that it comes with two hard drives and has support for RAID 1. "What's this geeky-sounding nonsense?" you might ask. "Why not just use one 500GB drive?" Let us explain.RAID (Redundant Array of Independent Disks) configurations are systems that employ two or more disks in combination for fault tolerance or improved performance. RAID 1, aka mirroring, allows the drive to create two separate copies of your data, one on each disk, in order to reduce the chance of data loss should one drive fail. Paranoid users will welcome its presence in the DriveStation Duo, particularly if they really, really don't want to lose their precious files. Actually, it doesn't take a paranoid user but small businesses pr home based busines as well as users with a lot of data files, photos or videos they don't want to lose will welcome the Buffalo DriveStation Duo USB portable drive.
