Transfer speeds to USB

[Ulfhednar]

I’m wondering if it’s just me or something that is a general issue.
I'm using v15.8 b3135 on Win11 x64

When using native Windows ctrl+x/c & ctrl+v to move files to attached USB drives I’m seeing very different TX speeds vs MCs’ copy/move commands With same file / hardware - I’m seeing MBs vs KBs on a USB3.0 link which leads me to suspect MC has something slowing the process. 
It starts out OK but then speed drops significantly to KBs using MC but using the MC dialog + win cmds it maintains MBs TX rates. 
Applies to NTFS > NTFS & NTFS > exFAT.

Can this be improved/altered?

Try using TeraCopy (free utility by CodeSector) —it greatly improves transfer speeds ! (especially Move operations which are sometimes instant, but other operations are faster as well when you use it !) It's a highly optimized file transfer tool.

Hard to say why you get that...  normally MC can detected and selected the correct read/write stratergy.
It also different what kind of USB device. is is a normal SSD/HDD or USB Memory stick.
Also security software making difference.. and other stuff.  hard to say why you have low speed with the limit information.
But everything that can be tweaked around file read/write can be tweaked in Read/Write stratergy settings,
you can tweak everything that can be changed.

Also Windows Copy Speed are often not real. depends on how you measure it. Sometimes Windows say it is done.. but what is done is just the writing to the cache. and all the data is not even written to disk yet.

Thanks for the replies. 
I'd wondered about teracopy but have been preoccupied with the ability to quickly use MC buttons.  I will have to test it tho!

ATM I see speed variations with SSD on USB connector & USB sticks (2 things I use all the time), sticks are always slower I think, but I tried moving a ~300mb video file to different things (so AV wouldn't be triggered), with Win cmds it was <1min, MC gave <3mins on the same port/stick.
I will need to spend some time with MC tx profiles & see if I can see any pitfalls.

In Read/Write stratergy settings you can enable to MC also buffer all the writes so you get extra fast write.. (It will do the same as windows. report that it is done before it actually is since the data only have gone to the buffers and not disk. and not wait for windows to say it has written everything)
Make sure the Write process uses both System And Drive cache in that settings for that R/W profile

Thanks Mathias.
Enabling use system cache in write/target for external devices has done the trick, speed is maintained & dialog closes appropriately.

Looks like I spoke too soon...
Files ~300mb to USB 3.0 stick, <20GB free space.
Tried MC first, cancelled after about 10mins, repeated with different file of similar size & took screen shot.
Then using MC panes ctrl+x / v - expected speed achieved, to be sure I ran a CRC check - OK.
Very different results.

Are you sure it used the Read/write tweaks you changed ? You can in log see what settings is used.
When writing data there is not much to play with.. it is bypass cache or not and write chunck size (how many bytes to write in each write operation) and if writes should be threaded or not.
There are so many external factor that affect the speed.

Also you cant just compare the number from Windows.. since that number say nothing. That is not a real speed.

But getting really slow speed in MC then I suspect something is preventing MC from going full speed and checking the data before it sends it to the device.
