Mac Pro accessory maker HighPoint Technologies is now offering a quad-port PCI-E 2.0 USB 3.0 RAID HBA called the RocketU designed specifically for Apple's high-end workstation. Each port is capable of the theoretical 5Gb per second performance for a combined theoretical throughput of 20Gb per second (real world use of USB 3.0 tends to be dramatically lower). The card supports both single disk and various RAID configurations including JBOD and RAIDs 0, 1, 5 and 10.
