If that is the case why does the specs for that device under performance say it will support speeds of 1Gb/s, 3Gb/s and 6Gb/s.Once upon a time, Stephen Morris <steve.morris.au@xxxxxxxxx> said:To test my hard disk performance I have run Kdiskmark and used the Real World Performance Profile. For its sequential read performance it is showing around 156 MB/s on my ST3000DM007-1WY1 (3TB Seagate Barracuda), which given that device support 1/3/6 Gb/s I/O speeds and the device is plugged into a 6Mb/s Sata port on the motherboard, is very poor performance.That's a misunderstanding of how things work. The SATA port speed is just an upper-bound on transfer, but has nothing to do with how fast a device can actually read data (similar to having a 1G network card and even Internet service doesn't mean sites will serve data to you at 1G). Traditional spinning hard drives typically do top out in the neighborhood of 150 MB/s... and in fact, the official spec from Seagate for that drive is an average read rate of 156 MB/s.

Steve
