My mobile workstation (i7, 16GB RAM) became really slow (even the mouse moves are shown with 1FPS), CPU usage at 100% even when nothing at all was running. After a few minutes even worse.
I have rebooted and tried to run an offline BitDeffender scan, which could not manage to parse a 100MB file in 10s.
Then I booted up using a mobile HDD, over just a USB2 cable. And it is even so faster like a rocket and with normal CPU usage.
Now I am suspecting my mSATA SSD (Samsung EVO 840)
Then I have downloaded Samsung SSD Magician and HDDTune and ran some tests:
The benchmarks look really meaningful:
Really low minimum and really high CPU usage, but even the maximum transfer rate is far below specs.
The SMART health status is OK:
And here is the speed map:
Is this the end of the SSD or the end of something on the motherboard - quite not uninteresting from cost point of view?

1the 840 Evo had perf issues when files were not accessed for a longer time. There was a firmware update which refreshed the drive more often. flash the last firmware. – magicandre1981 – 2017-11-16T16:12:24.733
have you tried the new firmware? – magicandre1981 – 2017-11-18T17:21:50.283
Yes, I have updated the firmware. The profile looks better, but still far below specs, still high cpu load. And the overheating is still there. – ZorgoZ – 2017-11-19T17:40:14.630
the 840 Evo has TLC NAND issues so the perf will never be the same as in the specs. which process has the CPU usage? if SYSTEM process, look at this guide to trace it
