    Slow internal hard drive tansfer speeds


    Hi

    I'm getting very slow hard drive transfer speeds. Both drives are SATA:

    Seagate Barracude Green 2TB 6Gb/s 5900RPM ST2000DL003

    HGST 4TB 6Gb/s 7200RPM HDN724040ALE640

    I'm transferring from the Seagate to the HGST. I'm copying over some video tutorial courses, they're quite big ~ 14Gb each. Each course has a number of videos averaging about 80-150Mb per video. I'm getting tranfer speeds of about 8-9MB/s.

    I've ran CrystalDiskMark on both drives and they're reported as what I expect. I've attached screen shots of the results.

    My motherboard is a Gigabyte Z170X Gaming 5 and I have 32Gb of GSkill DDR4 ram.

    As far as I know I think the chipset drivers are up to date.

    I'm at a lost why the transfer rate would be so slow. Any suggestions would be great.

    Thanks

    You drives seem to be running at SATA instead of SATA 3 (or 6 as it is also known). I assume your drives are connected to SATA 3 ports; yes? If so, the level of hard drive fragmentation and free capacity can affect hard drive transfer speeds. Also, having both drives on the same SATA 3 controller could impact performance. I suggest running ATTO benchmark as it gives a better picture of transfer speeds by filesize:

    Hi

    All the SATA ports are 6Gb/s ports and are from the Z170 chipset, no 3rd party controllers. I assume they will run in this mode? or Is there a way to check this or set this to happen? Also should the ports be populated in sequential order? ie 0,1,2,3,4,5?

    Thanks

    So I looked at your chipset and your mobo manual and it sure seems like they should be able to run SATA3 by default. You do have them set to AHCI; correct? The only other thing I noticed is that SATA ports 2 and 3 are physically offset from 0,1,4,5 so you might want to experiment by keeping your OS drive on 0 and try placing your other drive on 2. Just guessing though...

    Defrag and run ATTO please

    Yeah, SATA is in AHCI mode. I've read SATA port population doesn't matter but will give that a try tonight. Thanks for your advice dude.

    You are probably right; however, there is something affecting your transfer speeds on both drives and that is unknown at this point. Anyway, defrag you hard drives and run that ATTO. Good luck to you!

    I've read a lot of people are having the same problem and everyone seems to agree that transfers were faster in Win 7 which is what I distinctly remember as well. I might go back to win 7 and confirm this myself.

    That may be for some specific hardware configurations; however, generally speaking, the difference should be minimal. Now, if you look at my transfers speeds, they were no different on 7, 8 or 10, and your chipset is much newer than mine so I doubt you will find that to be true with your rig.

    ok cool. I'll try copying back some of the files back onto the original drive, defrag and run that app then copy those files back. finger's crossed it is just down to fragmentation.

    Wait! I just found these benchmarks for the Barracuda green. Maybe it is just that slow?:
