Help please! Very slow hard drive transfer 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. The read/write for the Seagate is 124/120, for HGST is 150/149 respectively.

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

Which controller are you using? Does that board have a non-Intel SATA controller as well?
You might also want to check SMART, to see if HDs are OK. (Use crystaldiskinfo--which is free.).
Also look at event viewer to see if you see any errors/warnings.

Could also be some heavily fragmented files as well.
Oh, and I don't see any attached pics?

Keep in mind the file speed has a huge effect. You mention the "courses" are 14Gb each but that doesn't really matter. The videos you say average 80MB-120MB. So that will be slower than if it was a single 14GB file. 8-9MB/s does sound slow unlesss there's a bunch of even smaller files. Copying thousands of 1MB files for example will take forever.

Thanks for the replies.

Crystaldiskinfo reports all the disks are good. I ran HDDScan and SMART info is all good. The board only has an Intel SATA controller.

XavierMace - I have noticed that some stuff I copy over at 30-60MB/s and copying from an internal drive to an external SATA via USB3.0 I get 90-100MB/s sometimes.

Sorry, I just re-read my post, I was half asleep when I posted it. It was supposed to read "keep in mind the file size has a huge effect".
