Today I stripped down and rebuilt my PC (to get rid of surplus cabling, and to give it a clean since it was pretty dusty in there), and everything is running fine.
Well, except my SSD (apparently).
I run speedfan from time-to-time, and I ran it after the rebuild to check that the temperatures were OK. This is what I saw in the S.M.A.R.T tab when I checked my SSD's health:
Meanwhile, the data for my two hard-drives shows this:
My two hard-drives are apparently in much better health than my SSD is, but maybe one thing to note is that the SSD runs on a PCI-E SATA3 controller, and the two hard-drives run on my motherboard's own SATA2 ports.
Should I be concerned, or is SpeedFan reporting a false-reading (aka, my SSD is completely fine)? My SSD is still under warranty, is it advisable to RMA it (since maybe this is a sign of imminent total failure)?
According to this forum thread:
Using your OCZ Toolbox app, your SSD's life curve SMART attribute is what you should watch; "0" is perfect
The life curve
on my SSD is reporting as 100
, so does this mean that my SSD is on pre-failure
:
230 Life Curve Status 0x0013 100 100 000 Always 100

Its to be expected that the rellocation value would be better on a SSD since data is continously being moved around within an SSD. – Ramhound – 2014-09-02T19:53:32.513
@Ramhound Don't you mean 'worse' or 'higher'? – AStopher – 2014-09-02T19:54:17.637
I mean better. I am saying that its to be epxected that the reallocation sector would be higher ( i.e. better ) because the firmware is continously doing write protection mechanics. This means until the end of a specific life of a cell the data is unlikely to have trouble being read/written which often happens with a mechanical disk which has physical platters which become unreable in certain sections of the platter itself. I say exactly what i mean by the way. – Ramhound – 2014-09-02T19:59:50.127
@Ramhound Gotcha. – AStopher – 2014-09-02T20:00:30.113
But as pointed out, unless you also monitor the amount of data SSD has written, the S.M.A.R.T data hold little value by itself. The data itself simply indicates firmware believes the drive is healthy. Without using SSD specific tools S.M.A.R.T data by itself hold little value. – Ramhound – 2014-09-02T20:03:35.050
