Other World Computing has expanded its Mercury Elite Pro Dual Mini bus-powered RAID options with two new HD-based and three new SSD-based pre-configured choices for up to two terabytes (2TB) of capacity using either Firewire 800, Firewire 400, USB2 or eSATA connections to achieve transfer speeds up to 300MB per second. The RAID unit is remarkably compatible all the way back to Apple OS 8.6 (using Firewire 400), and all the way up to Mac OS X Lion, as well as Windows 98SE and higher.
