Test System & Transfer Performance

Core i7 Test System Specs
- Intel Core i7 965 Extreme Edition (Overclocked @ 3.70GHz)

- Asus P6T Deluxe (Intel X58)
- OCZ GameXStream (700 watt)
- Seagate 500GB 7200-RPM (Serial ATA300)

Software
- Microsoft Windows 7 Ultimate (64-bit)
- ATI Catalyst 9.10

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.
