While the first Thunderbolt-equipped Macs appeared in February, dedicated peripherals have been a long time coming. Perhaps inevitably, the first to arrive are RAID drives, such as the Promise Pegasus RAID R6 we have here. While the Thunderbolt port is capable of carrying data at up to 10Gbps in both directions, a single-drive external storage device is limited by its SATA connection, throttling speeds at 3Gbps, or 6Gbps if the less common SATA 3 is used.
