This one does seem very slow, and it is not part of the raids. Maybe it is busy, something is using it heavily. SSD, you say?

This one is a trifle slow, compared to the other.
I noticed that when they were brand new last summer.

=== START OF INFORMATION SECTION === Device Model: PNY CS900 120GB SSD ... Rotation Rate: Solid State Device ... Does not say it is SSD
Are you sure? Besides that, I have my doubts PNY ever made or sold any type of storage that wasn't solid state.
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.
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? 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.
