Venturing into relatively new territory, LaCie released the 2big USB 3.0 as the first ever external drive to combine both RAID and the faster USB interface. The two-drive enclosure can run as JBOD (just a bunch of disks) or in a RAID 1 mirror for security but excels when put into a RAID 0 stripe for speed. At a peak 205MB per second, the stripe is faster than even a FireWire 800 or eSATA drive and can transfer large volumes of data in record time; LaCie claims a dual-layer 50GB Blu-ray could copy in under five minutes.
