Is this the case for all SMART values? Higher=better?
Yes, the non-raw values are always reported with higher meaning better. The raw values are the raw measurements/counts and they each mean different things.

I now found and followed this: https://blog.quindorian.org/2021/05/firmware-update-samsung-... And it seems to have worked. After extracting this updater tool and running it, smartctl kept showing the old firmware version (3B2QGXA7), but after reboot it now shows the new version (5B2QGXA7). I took the risk of running this while the OS (Archlinux) was running with the disk mounted (this is the OS install disk), and at…
The command can be simplified as isoinfo -R -i xxx.iso -x /initrd | gzip -dc | cpio -idv --no-absolute-filenames "root/fumagician*" if you don't want to go through the mounting and extracting everything.
However this seems like a systematic problem at Samsung.
What really stinks is that I've been recommending Samsung EVOs and PROs to relatives and friends for some years.
If I want to remain honest with myself I have to contact every one of them and have to run the SMART tests.
So now there are NO reputable SSD manufacturers left. Only reliable SSDs are MLCs from mid 201Xs especially Intel and Samsung.

A few months ago I already updated my Samsung SSD by following this procedure: https://askubuntu.com/a/1386451 . Theoretically they provide an image to boot from to do the update, but the image seems very outdated and did not recognize my keyboard so it was unusable.

After installing unzip, the firmware updated successfully.
Ask anyone with a circa-2014-ish Macbook Pro about Samsung SSD reliability. The samsung-made drives lasted about 5-6 years. Everything seemed fine, and then one day you'd get a spinning pizza of death, power down, power it back on...and your SSD was...completely gone. Doesn't even enumerate on the PCIe bus. It's just gone. Screw the SSD chipset manufacturers for not making sure that their controllers can at least a)s…
A recovery mode seems absolutely possible and I don’t care if it’s 100kbit over SPI. It’s better than losing everything.
SSDs are complex beasts :-) I've had an OCZ SSD in the past that also became read-only, in the sense that all changes after shutting down the computer were gone. If you rebooted everything was fine, but as soon as the computer was shut down and the SSD also ran out of power, it converted to the state before turning on the computer. That was so bizarre. Once I had a hefty Windows upgrade installed and it was gone afte…
sounds ideal for a public terminal ;)

Not sure why downvoted. A recovery mode seems absolutely possible and I don’t care if it’s 100kbit over SPI. It’s better than losing everything.
In 2021 I bought at least ten 870 EVO 4 TB SATA and six 980 Pro 2 TB NVMe. All devices failed within 6 months on barely used systems. Find some smart data here: https://thomas.glanzmann.de/samsung/ > The pattern is always the same: I have them configured in a raid 1. Once a month debian does a raid check. During the raid check Debian reads all data from both devices. I get uncorrectable read errors. I no longer use S…
Similar experience for me. Four 2TB 980pro in RAID-Z2. Since introducing the drives in August 2021 I've had to replace them five times. I think none of the original SSDs are left. Only between 5 - 25TB written on average. Usually individual uncorrectable errors caught by ZFS, but one drive just straight up died. I keep a cold spare these days. On the bright side, if the cycle continues, I'll never run out of warranty…
The warranty is from the date of sale of the original unit. Replacing one doesn't reset the warranty end date.
