A little over a year ago, CalDigit (http://www.caldigit.com) introduced the CalDigit VR min, a compact and bus-powered , two-drive RAID system with a quadruple interface.  The CalDigit VR mini is hasn’t gotten any bigger, but it can hold twice as much data and even outperforms the previous generation.

The CalDigit VR mini now supports RAID levels 0, 1 and JBOD, supporting speeds fast enough for high definition video editing, according to the folks at CalDigit. Using eSATA, the CalDigit VR mini can reach speeds of over190MB/s.  

It’s only two inches tall and five inches long — small enough to fit in the palm of your hand. The 1TB and new 2TB CalDigit VR mini cost US$499 and $599, respectively.
