Windows 10: Painfully slow file transfer speeds to External ssd's Windows 11

File transfer speeds to external ssd and flash drive using usb 3 painfully slow - tried all the obvious workarounds but no success - read somewhere about Microsoft releasing a patch ? I can see that this is quite a common issue has anyone managed to resolve it without resorting to standalone software

File Transfer Speed from Windows 11 to Synology NAS is VERY SLOW vs. Windows 10

I have a new Windows 11 PC and I'm noticing that the file sharing to my Synology NAS is very slow vs when I transferred files from my older Windows 10 PC.

File Transfer Speeds:

• Windows 11 to NAS (DS1520+) = 11.5 MB/s
  
• Windows 11 to Windows 10 = 112 MB/s (much faster)
  
• File size = 30GB
  

Note:

• Windows PCs and NAS are all Ethernet connected on 1GB home network.
  
• Running: Windows 11 Pro 23H2
  
• Running: DSM 7.2.1-69057 Update 5
  

Any suggestions on how to speed this up would be greatly appreciated. Thanks.

Copy Files from Hard Drive to SD Card - Painfully Slow Transfer

SD cards are usually always painfully slow nothing you can do about it unless you spend about 10 times the price and get the faster ones.

From what I remember the fastest I have gotten is around 8 MB/s on the cheaper type, I have never used the more expensive ones.

Here are the speed class marks.
Note: You probably have a class 10

 

USB transfer speed from external hard drive to external hard drive

Transfer speed is dependent on the 'Read' speed from your old hard drive as well as the 'Write' speed to your backup drive. Normally these should be quite fast but if there is a problem with either drive then this could slow down transfer speed a lot and 150 KB/s is so slow as to point to a problem somewhere along the transfer path.

I suspect your drives are HDDs, not SSDs, but I get 305 MB/s transferring between two external SSDs connected to two USB 3.1 ports. This is over 2000x faster than your transfer speed so I suggest you run CHKDSK with repair switch on both drives? See https://docs.microsoft.com/en-us/win...ommands/chkdsk
