Windows 10: PC is very slow transferring files to USB drive, but copying FROM the drive is fine - why?

Hi, I've just built a new PC and I'd like to move files between the PC and an external SSD Sandisk Extreme Portable 1TB. I'm able to copy files from the SSD to the PC without any problem. The transfer speed is around 300MB/s using a USB 3.2 port.I can also copy individual files or a few files at a time to the SSD. But when I try to copy multiple folders or a large number of files, it gets stuck at "calculating" the transfer time. I think it's not copying at all. It doesn't matter which USB port I use. I'm getting the same problem.The SSD works on my old laptop. I'm not encountering any probl

Slow speeds when copying on external drive

Slow Speed

Hiii..... Since you are facing from slow speed problems.. You need to take care of your computer very well otherwise it may stuck some day later.. So, first perform disk cleanup so that all your cookies are clear, update your PC with some antivirus. You can follow the steps and I belive it will be helpful for you.

USB storage devices can be optimized for either quick removal or performance. If optimized for quick removal, data transfer can potentially be reduced to a crawl.

To optimize your USB drive for performance:
1.Right click on the USB drive and select properties
2.Select the Hardware tab
3.Under All Disk Drives, highlight your USB drive and select Properties
4.Select the Policies tab and select Optimize for performance.
5.Press OK twice, and your transfer speeds should increase dramatically
Note that when your drive is optimized for performance you'll need to use the Safely Remove Hardware icon in the taskbar to eject the drive - otherwise you'll risk corrupting your data by just removing the drive from the port.

 

Slow speeds when copying on external drive

Hi all,

since I installed TeraCopy I started to monitor my copy speeds and they are un-usually slow. Here is a real example. Laptop specs are in my profile, I have 3 USB 3.0 ports + 1 Super charge (the yellow one). Regular 8GB USB 2.0 flash drive. It copies at exactly 6MB/s from my laptop. I put it on another weaker specs laptop- 16MB/s, (same flash drive, same file). I hoked to a 10 years old DELL laptop- same result- 16mb/s. Tried with external HDD, same slow copy speeds from my USB ports. Seriously?

One solution I saw was to go to Device manager->Drives->Policies and switch to "Better performance", but use the icon to unplug the drive. Haven't tested with my drive, but another showed no difference at all.

I have no un-recognized devices on the list:
