Hi,

Have a problem with very slow transfer speeds, when I built my current pc transfer speeds were about 80MB/s but now struggle to reach 10MB/s.
All drivers are up to date.
Have tried USB pen drives (Corsair Voyager USB 3.0 & DataTraveler G3 3.1) & external hard drives but the same.

I'm trying to transfer 300GB of files to the external drive.

Issue 2 is that some devices will only work in certain usb ports, for instance the Logitech unifying adaptor will only work on port 4, external hard drive (Seagate Expansion Drive) will only work on the 3.1 ports and the color monki calibrator will only work on 1 of the front USB ports.

Motherboard is MSI x99A Krait Edition and using Windows 10 Pro 64 bit.

Any help please?
thanks.
 
ok just uninstalled all the USB controllers and now get 15MB/s on a USB3 pen drive.

Have just bought an Anker external USB3 hub powered externally and also same speeds.
 
yeah running the latest BIOS mate.

Have just tried on my HTPC which is also running w10 and have the same problem. Both hard drive and pen drves.

I know the problem now points to the USB pen/hard drives but surely not all of them can be broken at the same time?
 
Have just ran USB Device Tree Viewer and it shows the drive is connected via USB 2.0.

Using the rear ports yes, the top 2 ports are USB 2.0 which have my mouse & keyboard connected to the rest are 3.0. (2 ports 3.1)

Not sure which controller the pen drive is connected to, it just shows mass storage drive.

Well you should definitely be getting full speeds then. I even tested my USB3 stick in the front USB2 ports on my case (cheap - has no USB3) and get 40MB/s write. Perhaps this is because everything is Intel on my board. I notice you have VIA and Asmedia in addition to Intel. It might be worth trying to pinpoint the Intel ports and using those.

edit: I noticed the VIA controller has microsoft in brackets which means it's using the drivers built in to windows. Check the VIA website for updated drivers. Ignore the microsoft in brackets next to Intel - they don't provide updated drivers.

ok, just installed the VIA driver (not showing microsoft anymore) but still the same.

The Pen drive is now showing as "Device Bus Speed: 0x03 (Superspeed)" in USB Device Treeviewer so is now been read as a USB 3 drive.

Will try to find the Intel ports although the manual isn't much help.
 
have found the Intel ports (2 below the 3.1 ports) and same speeds.

Also tried my external hard drive (mains powered) and got a constant 140MB/s.

Might grab my spare SSD at the weekend and install w7 to see if there is any difference.

Have you tried a different psu?

Had usb problems once on a customers pc and turned out to be the psu causing it :)

Have my old psu laying around I could try. My current psu is only about 3 month old and not having any problems elsewhere.

Have ordered a few different pen drives to try too
 
Borrowed a mates 32GB Sandisk pen drive which instantly went to 50+MB/s for a few seconds but dropped back to sub 20. This was on a 1.5GB mp4 file, while a 800mb file will copy at a constant 50MB/s. It seems anything above 1GB will copy slowly.

Have changed the write policy to "better performance" and my maximum speed was about 5MB/s. Write cache could not be enabled.

I should receive my new pen drives tomorrow which includes a SanDisk Extreme which has apparnt write speeds of upto 100MB/s.

If they fail I will try what postmanfw & labcoattech say.

Not sure what has changed as transfer speeds were OK a couple of weeks ago.

Recieved my Pen drives today. The Extreme drive works great averaging 65MB/s write speed (over network) 90MB/s local but the Ultra drive is the same as others, starts off around 54MB/s than drops to around 18MB/s.

Think it's a clean install over the weekend :(

Extreme drive copying 8GB single file.

Sounds like a motherboard issue, only way to be sure is to test the USB flash drive on another PC or get a USB 3 PCIe add-on card.

Also check the BIOS to make sure the USB ports are set to full speed.

have tried them on my HTPC and have the same problem, even with the brand new pen drives. Both are running w10.
 
ok have just got a BSOD with the error IRQL_NOT_LESS_OR_EQUAL.

Have viewed the .dmp file via BlueScreenView and it shows it was caused by driver hal.dll File Description: Hardware Abstraction Layer DLL.
Crash Address: ntoskrnl.exe+142760

any ideas?
 
ok mate, have just formatted my pen drive as per above, BIOS is back to default & all USB & hard drives have being disconnected (apart from mouse, keyboard & 950NVME drive) ... still have the same problem.

Have also tried on my brothers laptop running Windows 8 and get the same.

Everything seems to point to the USB flash drive, test it using h2testw 1.4 and let us know.

will do, I know the problem sounds like the pen drive but this happens on all my pen drives except the Extreme pen drive.
All of these were purchased from the rainforest place direct (no reseller) so surely they are not selling dodgy drives?
 
Have just finished testing the 3 pen drives I have on me.

Both are Sandisk Ultra
