I have been a dietpi user for a long time, I love dietpi, it is the best distro for me. But I’ve always been noticing a small mistake. I have somewhat slow reads and writes. I thought it was my raspberry pi4 but now I have a raspberry pi5 and the same thing happens to me. I have disabled hparm in dietpi settings and set it to 0 disabled. but I still get the reading about 45Mb/s and the writing goes a little better 90Mb/s sometimes 114Mb/s. My network is gigabit and the 2 disks are Seagates basics of 4 and 5TB, these are bought new
I have to add that I use a tplink brand 7-port powered USB HUB. Thank you for everything and for maintaining dietpi and excuse my bad English, I’m from Spain
the hub 7 ports tplink is USB 3.0
the hdds both are USB 3.0
do you get these “slow” readspeeds via Samba in your network or directly when working with the Pi?
If its about Sambaspeeds, you could try some tweaks…
when its about Sambashares, i made the experience that the filesystem, used onto your shared drive, has a huge influence to the transferspeeds too, i think it’s worth trying!
I had the best results using Linux-Filsystems, such as EXT4.
When I send data as a movie it goes at a stable 113Mb/s but when I cut a movie from the hard drive and transfer it to the PC again it only goes at 60Mb/s
I have tried better quality RED cat6 and cat8 cables
The drives are connected to a powered 7-way TPLINK HUB and everything is connected to USB 3.0.
The drive where you copy the data from is in both cases the same?
I had comparable effects, because i used a drive to cut the movies which was NTFS. The MaindownloadFS was EXT4.
I noticed differences in Sambaspeeds mainly when using rsync, it depends on the filesystem again.
My NAS-drive ist EXT4, i have multiple backups on different types of drives, with different filesystems.
The quickest ist EXT4->EXT4 , EXT4->NTFS or EXT4->EXFAT are slower.
