OWC has unveiled the Viper Pro, an external drive with Thunderbolt 2 support.
The Viper Pro is an external solid state drive (SSD) featuring two Thunderbolt 2 ports. The drive supports sustained data transfer speeds of up to 1350MB/s, and because it's a Thunderbolt drive, it of course supports daisy chaining multiple Thunderbolt devices together. It also features variable fan speed for quiet cooling.
The aluminum enclosure comes in two storage capacity. For $2,999 you'll get a 4TB SSD, while $4,799 will net you 8TB of storage. Both versions will be available for order at some point this summer.
