I have just done a test on my disk, and for some reason the transfer rate is just 50mb/second.I thought e-sata was upto 3gb/sec. I realise that from past experience that that might be gigabits per second, but that still be much higher the rate I have been getting.

i think for dock the hard disk speed of 50 MB/s is a reasonable enough but this speed for a cheap drive.

I don't think you are ever going to get 3Gbps. That's just marketing hype and a "theory." The most I've seen is like 186MB/sec on my machine and that is during initial "bursts" - I get speeds less than you when using USB. I know RAID runs a lot faster
