=== START OF INFORMATION SECTION === Device Model: PNY CS900 120GB SSD ... Rotation Rate: Solid State Device ... Does not say it is SSD
Ah, now I notice it in the model name.
Are you sure? Besides that, I have my doubts PNY ever made or sold any type of storage that wasn't solid state.
No parameters related to ssd, like Wear_Leveling_Count
170 Unknown_Attribute 0x0003 088 088 000 Pre-fail Always - 134
This is the only value that is starting to go bad, but we don't know what it is.
Could be nonsense from poor firmware I suppose.
No, it means that smartctl doesn't know about it. Maybe a more current version would know. Here: https://www.thomas-krenn.com/en/wiki/SMART_attributes_of_Intel_SSDs AA 170 Available Reserved Space Reports the number of reserve blocks remaining. The normalized value begins at 100 (64h), which corresponds to 100 percent availability of the reserved space. The threshold value for this attribute is 10 percent availability. So it is going down indeed. It is aging.
241 Total_LBAs_Written 0x0012 100 100 000 Old_age Always - 110
It does not say how much life is left. The Total_LBAs_Written count is absurd.
No doubt.
The question remaining is what next to do?
Maybe it needs trim. Do systemctl status fstrim In mine: Isengard:~ # systemctl status fstrim ● fstrim.service - Discard unused blocks Loaded: loaded (/usr/lib/systemd/system/fstrim.service; static; vendor preset: disabled) Active: inactive (dead) since Mon 2019-02-11 00:01:33 CET; 1 weeks 4 days ago Process: 11202 ExecStart=/usr/sbin/fstrim -av (code=exited, status=0/SUCCESS) Main PID: 11202 (code=exited, status=0/SUCCESS) Feb 11 00:00:01 Isengard systemd[1]: Starting Discard unused blocks...

I emailed the PNY support address I found in the Newegg reviews after starting this thread. No response as yet. Speed is marginally better logged out of KDE, but rather erratic in percent, not improved by fresh boot, nominally different in TW & 15.0 and definitely dismal compared to the rotating rust. These are all from 42.3:
Timing buffered disk reads: 28 MB in 3.27 seconds = 8.56 MB/sec Timing buffered disk reads: 24 MB in 3.19 seconds = 7.53 MB/sec Timing buffered disk reads: 26 MB in 3.16 seconds = 8.23 MB/sec Timing buffered disk reads: 26 MB in 3.22 seconds = 8.07 MB/sec Timing buffered disk reads: 24 MB in 3.37 seconds = 7.12 MB/sec Timing buffered disk reads: 24 MB in 3.23 seconds = 7.42 MB/sec
When it was new last summer: Timing buffered disk reads: 770 MB in 3.00 seconds = 256.62 MB/sec
