The sundry CalDigit 2TB VR Mini Dual Drive Array is an ultra-portable, bus-powered 2TB RAID system with five interface terminals and four interface options - affording anywhere from a brisk 400Mbps transfer rate, all the way up to the ultra-swift, 3Gbps flash of eSATA data transfer. It has dual drive modules that are hot-swappable; each one can be expeditiously replaced when a drive is damaged, an archive established or when your storage is expanded. Availed by its Quad Interface System, the VR Mini supports individual ports for high-speed USB 2.0, eSATA and FireWire 400. It has two FireWire 800 terminals as well.

The burgeoning possibilities from having four interface options make the VR Mini a portable problem-solver. It can simultaneously daisy chain via one FireWire 800 port, transfer data via another FireWire 800 port and use the USB 2.0 interface for power. The VR Mini can also daisy chain via one FireWire 800 port, transfer data via the single eSATA interface and use the other FireWire 800 port for a bus-power supply. The range of connectivity gives the VR Mini a degree of variance, which reveals how malleable the CalDigit array is in almost any situation.
