Wondering if anyone might have any idea why copying between these two drives has decided to slow down so much. It was fine earlier in the day then it decided to slow down a lot. I could only get it to go as fast at the beginning of the screenshot by completely turning of the pc for half an hour. Its Windows 11, internal drive to external drive.

Copy can slowdown due to copy buffer being filled and drives not fast enough to write from there.

 

Internal vs external doesn't say much.

 

Are both HDD or SSD or a combination?

 

The external drive is USB 2 or USB 3? 

 

If HDD, are they fragmented? 

 

Have you run a defrag retrim on SSD?

 

Have you enabled Windows write cache for both devices (and disabled buffer flushing if you have a UPS/battery)?

 

For external drives the options are Quick Removal (slower) and Better Performance (faster but you must use the USB icon to eject the device or risk losing files).

The writing drive may have a fast cache and can only sustain a high speed for a period of time. I see the same thing with my Samsung QVO drive. Great drives for *most* of what I do, but remuxing a large file I will see the first part completed quickly, and the remainder will take significantly longer.

They're both spinning HDDs. As you can possible see, its basically a really big movie file with a few extra jpgs.

 

Fairly sure the external is usb3. I think it goes into a usb expansion card I added, which I guess could be a bottleneck if all the other drives plugged into that card are transferring stuff about, but they're not. Don't think the drives are very fragmented, especially the destination drive. Earlier today it was doing over 100MB/s (units ?), now its a fifth of that.

 

Haven't had a chance to check any caching yet.

 

Now I'm trying again with another one, its averaging 97MB/s, will see if it lasts...

Have you checked the settings I screenshot for you?

The external drive is set to Quick Removal, the internal one has the top box ticked, the second unticked.

 

Having said that it copied the second time at 97MB/s all the way through - time for file/movie number three...

Set the external for Better Performance - might have to restart your computer. It should make things a bit faster (providing you have some spare memory available).

Hokay, I'll have a go. Might not get a chance tonight though...
