The Vi-On does exactly what an external enclosure should do – provide a cool and secure housing for that spare HDD you may have lying around. Installation takes only a few minutes and is simply a matter of snapping in the drive and then plugging it in to your PC. Both USB and a high speed eSATA interface are supported to make transferring files of all sizes a quick and easy process. For those times when portability is needed and the limited storage of a flash drive isn't enough, the Vi-On paired with a SATA HDD is a handy alternative.
