Speed Up SATA Drive

Postby dnzota on Fri Oct 30, 2009 5:09 pm

Does anyone know how to speed up transfer rate on a SATA II hard drive? My current transfer rate is 20-25 MB/s. On windows I have 100-150 MB/s - I can move a 700 MB .avi file in 4-5 seconds. What is the problem in Linux? I'm sure it can do way better than 20MB/s.

One more thing: mouse has spikes when I copy something.

Thank you!

More context needed: hardware
The motherboard model # would help, and if you have that information
    An Internet search on that model # + Linux + sata might get you a quicker answer..
Where is that file you are transferring in Linux with that slower rate, is it on the windows partition ?
--how does windows do in transferring data from the Linux partition into windows in terms of speed
    I guess I have to assume some things with no context provided
    • You have windows and Linux installed into there own partitions, so that they boot separately
    • You may have a shared directory (folder), but on which OS ?
    • If you don't have a shared folder, you mount the alternative OS partition depending on which OS you boot
    • If the boot OS is windows, how does it see the Linux file system
      --which methods do you use ?
    I could go on and on..but you must be getting the idea by now..

I don't know what mouse has spikes means
    but mouse or system instabilities makes it sound like power problems..

And how do you determine the transfer rate in Linux

In a terminal, check
    hdparm -t /dev/sda
    --where /dev/sd? is your Sata device hard drive /partition
Do you have a clip on that drive setting it into Sata 1/II mode (150MB/s), ,lowest speed for compatibility with mainboard chipsets..

sata drive clips, jumpers..

    In fact, considering that no single SATA drive can actually sustain transfer speeds above 150 MB/s (not even 100 MB/s), the faster interface is probably the most useless of the new features defined by the committee. It'll only give you an advantage when using port multipliers. NCQ, staggered spin-up and hot-plugging all make a much bigger difference, especially in server environments. The 150 GB Raptor, for example, supports all those features, but uses a 1.5 Gb/s interface (which doesn't prevent it from being faster than drives with a 3 Gb/s interface, BTW)"
