Windows 10: USB 3.0 Transfer Speed Capped at <1 mb/s After Running Out of Storage.

Hello,I was using a photography program to save a live image stream from USB3 to disk when the program crashed and prompted an error similar to "out of memory, this typically happens when pc storage runs out"Ever since this happened, all of my USB transfer speeds have been typically <1mb/s both for transferring files to external hard drives and streaming with the same camera.I've updated windows, uninstalled and reinstalled USB drivers, and made about 50gb of free space.It's only the USB ports that can't handle fast data transfer, I can move and read large files on the disk at normal speeds

:)

 

Slow write speed of transfer

My dell 7577 core I7 1050ti model has a slow transfer speed. I transferred a 5 gigabyte file to an external USB 3.1 Kingston DT50 and I got write speed of 8 MB/s. and the read speed was capped at 21 MB/s although
I used to get at least 80 MB/s read speed. Please help!

 

USB 3.0 transfer speed drops to 0 only on one port. USB port and external drive are NOT defective.

I have a Dell XPS 13 laptop with two USB 3.0 ports. I connect a Seagate expansion drive to the left USB port and transfer a 4GB test file. It transfers about 1GB at 150MB/s and then transfer speed drops to 0. Then it picks up again after 3-4minutes, then
drops again intermittently.

I connect the same Seagate drive to the right USB port. The same 4GB file transfers with a constant speed of approximately 150MB/s. Thus the Seagate drive is not defective. Perhaps the left USB port is defective.

I connect a Sandisk 128GB flash drive to the left USB port (that is now suspected defective). It transfers the same 4GB file with constant 130MB/s speed, no speed drops!

Each step is reproducible 10x.

I am out of my wits here.

 

USB Transfer speed very slow on windows 10

Try with this

Method 1

Change Hardware Settings for Better Performance

The hardware settings require the external hard drive to remove from your machine safely, so safely disconnect your drive from the computer after finishing all the steps.

Step 1. Open Windows File Explorer and locate your external hard drive. Right-click the external drive icon and choose "Properties" from the drop-down menu.

Step 2. Choose "Hardware" tab, which will display the list of all disks mounted on the particular computer. Select the desired disk you want to improve its transfer performance and click "Properties" at the bottom of the window.

Step 3. In the device properties window select "Change settings".

Step 4. A disk window will pop up. Click the "Policies" tab and select "Optimize for performance".

Step 5. Be alert. You must disconnect the device safely. Right-click the tray icon and click "Safely remove USB Mass Storage Device".

Method 2

Turn off Auto-Tuning Feature in Windows 10

Don't let the auto-tuning feature retards the file transfer speed in Windows 10. You can only disable the feature by five steps.

Step 1. Press Windows key + X and select Command Prompt(Admin).

Step 2. Type "netsh int tcp set global autotuninglevel=disabled" and press Enter.

Step 3. Now try to transfer the files and check the data transfer speed.

Step 4. Again go to Command Prompt(Admin) and type "netsh int tcp set global autotuninglevel=normal" and press Enter. This will turn on the Auto-tuning again.

Method 3

Check and Repair System Errors

Corrupted Windows 10 file system could disable, interrupt or slow down the file transfer speed, so let's use the System Maintenance Troubleshooter to repair the wrong files.

Step 1. Open Control Panel and click on the Troubleshooting icon.

Step 2. Select View all in the top left corner.

Step 3. Run System Maintenance Troubleshooter.

Method 4

Turn Off RDC

RDC or Remote Differential Compression has a similar goal but it utilizes alternative ways to help you synchronize large chunks of data. It compresses the data during the network sync, but it can also be a drawback. That’s why we suggest disabling it. If the
problem isn’t solved, you can always re-enable it and move onwards through the list.

Here’s how to turn off RDC:

Step 1. In the Windows Search bar, type Turn Windows and open Turn Windows features on or off.

Step 2. Scroll down and uncheck the “Remote Differential Compression API support” box.

Step 3. Confirm changes.

Method 5

Disable Drive Indexing

In order to speed up the access to files stored on the local storage, Windows offers Drive Indexing. When enabled, this feature will index all files and substantially reduce the waiting time when you search for them in File Explorer. This is a great feature
if you have dozens of similar files which and helps you distinguish them and access them quicker than usual.

However, even though it should work when PC is idle, it sometimes doesn’t. And you can imagine how it can slow the data transfer if starts indexing files while the copying is still at hand.

For that reason, we suggest disabling it. At least temporarily. Here’s how to do it:

Step 1. Open This PC or File Explorer.

Step 2. Right-click on the partition you want to relieve of indexing and open Properties.

Step 3. Uncheck the “Allow files on this drive to have contents indexed in addition to file properties” box and restart your PC.

Method 6

Disable your antivirus

In a similar manner, as Drive Indexing can slow down copying, an antivirus might, as well. Of course, instead of indexing, it’s real-time engine might scan them for malware presence. Besides slowing down the transfer, it can also affect the whole system and
hog on the resources. Which adds up to an already heavy burden. That’s the reason why you should disable it until all files are transferred. Obviously, you would want to enable it afterward.

Here’s how to disable Windows Defender:

Step 1. Open Windows Defender Action Center from the notification area.

Step 2. Choose Virus & threat protection.

Step 3. Under the Virus & threat protection settings, click Manage settings.

Step 4. Toggle off Real-time protection.
