hello, A few years ago, I did buy a Mintbox Mini 2 computer. This machine now has 4 GB of RAM memory. In the specifications, you mention that the maximum RAM size is 16 GB. However, when I move to the page “fitlet 2 built to order”, I see that you offer 32 GB, 64 GB and also much bigger. So, now I a...

now I am puzzled :?: I have added libata.force=1.5G to /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet libata.force=1.5G" I did run sudo update-grub I did check this in /boot/grub/grub.cfg linux /boot/vmlinuz-4.19.0-5-amd64 root=UUID=c13aae11-e70b-4c32-95d4-887063631a09 ro quiet libata.force=1.5...

did you try to remove apparmor ??

Fred44nl, I don't really understand how apparmor ties into the problems of the SSD becoming read-only or of slower (SSD) performance, as apparmor deals with application permissions, not really I/O. I'm running Tumbleweed now, although I could boot Mint to run a test, if that would help you and/or F...

if you like you can uninstall / remove this service.
if only, just for testing.

did you try to modify the kernel parameter, as mentioned ?

GRUB_CMDLINE_LINUX_DEFAULT="quiet libata.force=1.5G"

Does the current version of Mint has a service running called apparmor ??

I have a Kingspec m2.SSD, which gives me no errors. done the dd-stress-test before, without problems. but what I find strange, is that dd if=/dev/zero of=test bs=1048576 count=2048 gives me a speed of about 75 MB/s but the specs from Kingspec mentions much, much higher performance. as a comparison, ...
