Very Slow Transfer Speed on Raspberry Pi 4 with OMV 5

  • Hello


    I have different problem. Fast reading RP->PC (70-100) and slow writing PC->RP (8-20) by Samba. Results are the same with ntfs and ext4. There is Windows 10 on PC. Writing from 2 different SSD on PC sometimes can give a little faster speed (30-40) for a small moment.



    Reading from RP with WD20EZRX



    Reading from RP with WD40PURZ (NTFS) gaves 80-100.


    USB 3 cardreader (microsd 128gb u1 Samsung evo) in second usb 3 port has same problem.



    RP 4 4gb + original PU + cooling + 2020-08-20-raspios-buster-arm64 + clean OMV (wo torrents, dockers and other)

    microsd 32gb class 10 u1

    WD 2 or 4 tb 3.5 + ugreen SATA3-> USB 3 with external power unit


    Same HDDs gaves 110+ directly to PC through USB 3 adapter.

  • There are several possible reasons for speed and data transfer problems, such as outdated hardware or changes to one node or several network segments. You can try disabling all unnecessary features, auto-upload, torrent, etc.

  • hi everyone,

  • i have the same problem rasp4 omv5 with

    Smb/cifs minidlna . With rasp4 with raspian buster with desktop and minidlna and openvpn transfer rates above 100 mb/s

    Usb3 with ssd.


    Then i changed enable write cache. No it is 110 mb/s again

    this is under storage / disks/ edit.

    Shit now it is dropping again from 110 to 25 mb/s

  • write cache was allready enabeld in my case.
