FEATURES- DriveStation Quattro TurboUSB - 4.0 TB
       The DriveStation Quattro TurboUSB uses four separate hard drives for 
        greater reliability and security. In RAID 1 mode, redundancy 
        protects your data from drive failure, while RAID 5 offers a good 
        balance between storage capacity and security. Those who need a 
        maximum of storage can choose RAID 0. The DriveStation Quattro 
        TurboUSB also includes simple Plug-n-Play connectivity using
        USB 2.0 and eSATA Connections.

        supports high transfer rates - up to 100 MB/s! DriveStation Quattro 
        TurboUSB lets you store, backup, or easily transport large files

        device. It supports RAID technology, ensuring that your data stays
