Hey,
im getting slow write speeds on my SMB share (15-20MB/s), the download is fine with >100 MB/s.
Im connected wired via windows 10 and im using a SMB share.
My setup:
- Raspberry Pi 4b 4GB
- OMV 5 running on raspios-buster-armhf-lite
- 2TB USB 3.0 HDD (SATA) connected on the 3.0 port with external power supply for the HDD
- Connected to gigabit router, everything wired with cat 6 cables (router shows Gigabit connection aswell)
I checked the speed of the HDD with
Result is:
Code
Timing O_DIRECT cached reads: 334 MB in 2.00 seconds = 166.62 MB/sec Timing O_DIRECT disk reads: 412 MB in 3.01 seconds = 136.91 MB/sec
I also tryed a Samsung T5 SSD, with it i get about 70-80 MB/s write.
I also checked my network speeds with iperf3 which results in the following:
