I think I finally got this sorted. You have been right, Qu: It was no overheating issue. Just completed a scrub of 2 TiB data. Twice in a row, first on TTY without loaded desktop with about 3 GiB/s, then on desktop with power-profiles- daemon set to performance mode with about 3,8 GiB/s. Sensor 2 of SSD temp went up to 101 degree Celsius and it was no issue. What did I change? I upgraded firmware from 4B2QJXD7 to 8B2QJXD7 after in a dialog with AI I was hinted about issues that users lost their device at least temporarily after unsafe shutdown. Or even needed to send them in for repair. Luckily I never had one of these. However they also wrote something interesting about read-operation stability: ----------------------------------------------------------------------- * (8B2QJXD7) To improve read-operation stability. (Release : December 2025) * (7B2QJXD7) To address the intermittent non-recognition and blue screen issue. (Release: September 2025) * (4B2QJXD7) To address reports of high temperatures logged on Samsung Magician. (Release: December 2024) *990 PRO I 990 PRO with Heatsink will be manufactured using a mixed production between the V7 and V8 process starting September 2023. ----------------------------------------------------------------------- https://semiconductor.samsung.com/consumer-storage/support/tools/ What can I say? With 4B2QJXD7 a scrub of more than 1 TiB data was always interrupted with SSD being gone until forced restart of the machine, unless I paused and resumed it myself quite an amount of times. With 8B2QJXD7 two scrubs of 2 TiB in a row completed without any issue. Happy to have this sorted. Thanks for firmware update to Samsung! So make a backup and update your firmware! What a mess, really: Just took some years until I finally seem to have a fully working product. And it has not been the first firmware issue I have seen. Not even the first issue regarding this SSD model. Also I still remember "no operating system found" with Intel SSD 320 after unsafe shutdown with a firmware that should even fix this issue and despite this SSD even having some sort of Power Loss Protection (PLP) unlike the Samsung 990 Pro. Another note to Samsung: Pretty please update the way you create your firmware ISOs. Kernel 4.5.3 and it does not even boot on my laptop? You gotta be kidding me. Sure I can extract the update tool from initrd and run it manually, but really? How about just going with Linux Vendor Firmware Service via fwupd? Then I would have seen this update much earlier.
