Windows 10: Extremely slow USB 3.0 transfer speeds.

AMD Ryzen 7 5800X 8-Core ProcessorWindows 11 23H2OS Build 22635.4145Windows Feature Experience Pack 1000.22700.1039.0 I've been putting up with USB 3.0 file trasnfer speeds of maximum 30Mb/s dropping to less than 32Kb/s when transfering large files, 1Gb of more. Tried many different USB sticks, made sure caching is enabled, tried it caching disabled. All to no avail. Came to the opinion that it was my ASUS X570-e Gaming Wifi motherboard at fault.Then was messing about with a Linux Mint distro on an old 2.5 SATA drive and tried sending a 3.5Gb file to one of my slow USB 3.0 sitck

Extremely slow USB 3 HDD transfer rate on one PC but not the other

I have this Transcend Storage Jet external HDD. I was using it with my desktop Win 10 which supported USB 2.0. The transfer rate was satisfactory over 15MB/s. However, when I tried it on my new Lenovo ideapad 510 which supports USB 3.0 and using its USB 3.0 port, the transfer rate is going at a few 100 KB/s.

The copy window seems to pause a long time interval and only updates the speed and progress bar for just 1 frame every so often. Below is the CrystalDiskMark of this drive:





I've also tried the USB 2.0 ports on my laptop. The results are similar except for SeqQ32T1 and Seq which achieved > 30 MB/s

I've tried the following methods.

Disable Quick Removal Method

I've tried the most accepted answer of this: Extremely slow USB transfer speed but the problems are:

1. It doesn't work
   
2. My old PC also does quick removal and there was no transfer problem.
   

TeraCopy method

However, using TeraCopy, the speed can achieve 32MB/s with the USB 2 port on my laptop. But this is just avoiding the problem, not actually solving it. Actually, the result is exactly the same using Explorer to copy.

 

transfer speeds ,copying files extremely difficult

transfer speed to 3.0 usb from explorer file in pc extremely slow,worst i ever seen.all day to transfer one iso file.

 

Slow transfer speeds to USB on Windows 10

Hi Richard,

Welcome to Microsoft Community.

I'm Hahn and I'm here to help you with your concern.

It sounds like you've managed to resolve the slow transfer speed issue by performing a full format on the problematic USB drive, which took quite some time but ultimately restored the drive's functionality. That's great to hear!

A full format essentially wipes the drive completely and rewrites the file system structures, which can fix underlying issues related to the drive's performance. If others are experiencing slow transfer speeds specifically with one USB drive, attempting a full format might indeed be a helpful step to consider.

For anyone encountering similar problems with slow transfer speeds on a specific USB drive, your experience could provide a useful troubleshooting tip. Thanks for sharing your solution!

Your Sincerely
