Windows 10: Slow transfer speed to local NAS on PC1 and normal transfer speeds on PC2

Hello everyone, I am desperate at this point to try and find out what is happening! Basically I have a WD NAS EX4100 where the normal local transfer speeds over the network are arround 100Mb/s, wich all my pcs archived up to this point. After changing my motherboard a couple of days ago the speeds on my main PC, the one with the MOBO swap droped to 30Mb/s, like they are capped. This happened straight after installing windows without me even instaling anything on the PC! The other one still transfers at normals speeds but this one acts like its limited! It's worth mentioning that downloads fr

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.

NAS transfer speeds


Whats a good speed for transferring files from PC to NAS? I am currently transferring a single large file from the PC to the NAS and its getting a speed of around 20mb/s.

The connection between me and the NAS is powerline 1200 with gigabit ports and cat 6 cables. The route has to go from my PC downstairs to the main powerline then up to the NAS (I assume thats how it works, for all I know it could be going direct from PC to NAS).

 

NAS transfer speeds


Hi there

what are you using as a NAS box. Windows 10 should be just fine. The other thing is if you are using those electrical thingy's for Ethernet connection they can be hideously variable in performance.

I'd check your Network stuff first - the Wifi option works for me (wifi Ethernet bridge with 2nd router). If your network connection is fine I'd suggest a cheap RAID controller and improve HDD performance - but if you've got SATA connections the max theoretical throughput should be at least 3 GB/s - on modern HDD's could be 6GB/s -- although you won't actually get that speed from the HDD's themselves.

Can you also test running a file transfer from your computer to an external USB HDD -- the bottleneck might actually be in the PC !!! and not the NAS. USB2 external device will probably transfer at 20 - 40 mb/s , USB3 external HDD probably 100 - 150 mb/s (these are for portable self powered HDD's).

If the computer is slow then that's it -- NAS should be fine. If you have USB ports on the NAS see what HDD transfer is directly by connecting the device to the NAS - most decent NAS boxes will have at least one USB 3 port.
