    VERY Slow transfer rates between separate internal HDD's


    I've got a 2Tb disk which is almost full. I'm trying to copy the contents to a 3Tb disk, however, i'm getting ridiculously slow transfer rates. I've tried cloning, and it gives me estimated completion of cloning of over 30 days.

    I've tried Teracopy, and it gives me similar estimates. I'm copying an Itunes archive full of movie files typically around 3Gb - 5Gb in size.

    I have done some benchmarking tests, and it seems that my destination disk has some issues.

    Source Drive: (2Tb):

    Destination Drive: (3Tb):

    Clearly there are some issues here, but I'm not sure how to proceed. The drive is newly formatted/partitioned.

    Anyone have any thoughts?

    Many thanks

    Have you already tried to copy things over in "clumps" rather than all at once? I.E., what happens when you copy just one folder at a time?

    Use built in robocopy it's faster what anti virus are you using as this can scan on read and again on write slowing it to a crawl

    Found the problem it was the 5.25 bay my drive was installed to. Moved it to one of the main internal case bays and its improved hugely without the dips.

    Thanks all!

    That makes no sense. Must have had a problem with the cable/connection which changed when you moved the drive.

    I agree it makes no sense, as the bay has a slot for my main C: drive which is an SSD which gives no performance problems at all. Maybe it's a problem with that bay which is an aftermarket addition to my tower. Either way, the drive is working fine now :)

    Oh, does your case have actually bays for hot swap drives or something? If it has a backplane, it's possible you have a problem there.

    The bay I purchased to fit into a 5.25 slot in the front of the case has slots for a standard HDD and an SSD too. SSD is working fine, clearly either the bay or cabling to the other HDD was faulty. I'm getting 65Mb/70Mb per second now. Before it was just Kb's.
