Hi,

On Odroid HC1 512GB SSD with Armbian_20.02.1_Odroidxu4_stretch_legacy_4.14.170 I've got great SSD SATA samba write speed - 110 MB/s! But I have poor only 35MB/s on Armbian_20.02.1_Odroidxu4_buster_current_5.4.19_minimal

With Armbian_20.02.1_Odroidxu4_bullseye_current_5.4.19 I have the same poor 35MB/s speed.

I've done three identical installations using my checklist:

Spoiler

#Armbian install on Odroid HC1
# Flash Armbian_<>.img

#Upgrade
apt update
apt upgrade

#Move rootfs to SSD
# Make rootfs partition
fdisk /dev/sda
# Make filesystems
mkfs.ext4 /dev/sda1
mkfs.ext4 /dev/sda2
# Mount it to specific directory to use your SSD.
# Make new directories for SSD.
mkdir -p /media/system
mkdir -p /media/data
# Use /media/systemdrive as a root partition, and /media/data as a data partition.
mount /dev/sda1 /media/system
mount /dev/sda2 /media/data
# Check if it is mounted properly.
df -h

I think something wrong with 5.4.19 kernel builds.

I need to move forward and begin to install apps, but I'm stuck in this testing loop :)

Any advice would be appreciated.

We needed months to hopefully make it stable and usable which you obviously didn't even notice.

Igor, I really appreciate the work of software developers, as I myself do it as far as my abilities and capabilities are. I did not want to offend anyone. I just wanted to report the results based on the tests I did and I hoped to get a bit info about that I couldn’t find on the forum.

I didn’t register an issue on github but wrote it there. Isn't this a support forum?

By the way I've finished with Armbian_20.02.1_Odroidxu4_buster_legacy_4.14.170 just now and as expected it works well - 100 - 110MB/s transfer speed from Windows 10 PC to HC1 sumba share

Kind regards

Use (old) kernel builds that are much more tested.

If the answer is not on the internet its clarifying is usually related with high costs (many things is unknown or changing fast) which is why such support is almost never available to end users.
