Given that the A-DATA SH93 is limited to the USB 2.0 bus, transfer speeds maxed out at a little over 30MB/s when copying data. With a download speed of 33MB/s and an upload speed of 27.7MB/s, the SH93 performs like a high-speed USB 2.0 device matching the 2.5" Samsung portable drive and the OCZ Throttle. Of course, the latter had the advantage of being able to use an eSATA interface which greatly improved its performance.
