What is the model of your 1TB drive? Is it one of those new 4Kb-sector ones, such as WD EADS/EARS series? In this case it can be a case of mis-aligned partition - though 1Mb/sec is a bit too slow even for that – Sergey Oct 3 '11 at 9:49

The files might be badly fragmented. You can check that with the filefrag command. Also there might be a problem with the disk. Check /var/log/dmesg for errors relating to that disk.

That filefrag utility was a neat pointer. If it's not that then either your disks are in terrible shape or something on your system is syncing so often that you're not able cache enough of pages to achieve any sort of respectable throughput.

hdparm -tT /dev/sda will give you a fair idea of what your disks can do.


/dev/sda: Timing cached reads: 1370 MB in 2.00 seconds = 685.02 MB/sec Timing buffered disk reads: 164 MB in 3.03 seconds = 54.18 MB/sec

If your buffered cache reads are no where close to this then there's your problem

Not sure if this helps, but I once had an Athlon 64 machine whose motherboard had some sort of problem with the Ubuntu drivers and gave a very slow transfer from/to the attached HDD's. I think it was a Gigabyte motherboard, and this was several years ago.

If I were you, I would search specifically for problems based on your motherboard, although another good thing to note would be whether the transfer was ever faster on your computer.
