We were happy with the Vantec NexStar Hard Drive Dock's performance. We tested it with Windows 7 64-bit and a few different internal hard drives.
When tested with a USB 3.0 connection, the device registered sustained throughput speeds of 99.8MBps for the write test and 113.1MBps for the read test. When used with a USB 2.0 port, the NexStar also did well with 26.71 MBps (write) and 37.8MBps (read). These score were within the average of the fastest USB 2.0 external hard drives we've tested.
