![]() ![]() On the other hand, I've discovered Pi's internal SD card being terribly slow which correlates with a terrible Samba upload speed to HDD: $ sudo dd if=/dev/zero of=~/blob bs=16M count=100 status=progress oflag=directġ677721600 bytes (1.7 GB, 1.6 GiB) copied, 90.1067 s, 18.6 MB/s This is also not a network: write/read to/from a Samba share backed up by a RAM-disk are >100MB/s. dd tests tell it can perform a lot faster at the R Pi: $ sudo dd if=/dev/sda of=/dev/null bs=16M count=100 status=progress iflag=directġ677721600 bytes (1.7 GB, 1.6 GiB) copied, 18.5466 s, 90.5 MB/s I'm pretty sure it's not HDD (although it being NTFS-formatted). Download from Samba share: ~19MB/s (it actually starts with ~60MB/s, but then heavily drops and fluctuates randomly between 9MB/s and 24MB/s)ĭuring Samba upload/download R Pi CPU is no more than 50% loaded and there's spenty of memory as well.I have both devices on a 1Gbps Ethernet network, still transfer speeds are: Samba server is set up to use this disk as a share:.External USB 3 HDD is attached to the R Pi and auto-mounted via /etc/fstab.This article briefly shows how to measure and improve the HDD performance of your server. Before installing the system, I wanted to see the performance differences of various disk, their read speed, and their local and remote, via SAMBA, write speed. I'd really like it it be Samba because at lease 1 Win10 machine is involved. In my IOT Stack, a Raspberry Pi with an external connected disk serves as a SAMBA server. So, I'm trying to setup a Samba share on my R Pi 4 for my home network. ![]()
