S.M A.R.T. data on SSD what should I be looking for

vbimport

#1

I’ve had my Kingston 120gb SSD for < 3years (It’ll be three in Sept)

But some things I see in Speccy readout of S.M.A.R.T. is disturbing,
so what should I really don’t know what I’m supposed to be looking at

Could someone give me specific clues as to what parameters should make me panic and order a new one?

Parameter E6, Life curve status shows as 100, the raw data as “0000000064”

Parameter E7 SSD Life left = 0

But all parameters show in speccy as “good” and show in green

I’m confused…

Can you post a copy of all the SMART attributes reported by your drive? They vary from drive to drive.

Sorry about the scrambled columns…

For this particular SSD with the listed SMART fields, I would THINK about panicking when any of the following increases (Real, Raw, or Current value; they’re all currently at 0):
-retired block count
-program fail block count
-erase fail block count
-program fail count
-erase fail count
-reallocation event count

And to kinda gauge where the drive is overall, look at the “Current” value for SSD life left. It’s currently at 92, which is well above the threshold (10). If you find the value decreases in a large chunk, you’ll likely find a bunch of write errors have occurred (programming or erasing). Otherwise, the drive should be fine for some time. Of course, backups are always suggested.

If I’m reading it right, it looks like you’ve written (& read) more than 30 TB over the life of the drive. Does that estimate sound about right?

Depending on the Kingston drive model it is, 30 TB might be about half the rated write amount for the entire drive. If that’s the correct amount of writes your drive has encountered, the drive is fairly okay at keeping the wear & tear level across the drive, so it shouldn’t be a problem for around 1.5 to two years assuming linear progression. (Conservative estimate, as the drive is the OS drive, and some of the NAND will be rewritten fewer times due to OS files rarely being rewritten compared to some other types of files).

Albert, Just for MY knowledge, what is SMART and how do I check it out? never heard of it until this thread. I am going to have to go back to school. 15 years since I was in a classroom.

I’m not Albert, but I’ll answer this as far as I can…

S.M.A.R.T. (or SMART)= Self-Monitoring, Analysis and Reporting Technology.

And on second thought… Wikipedia has a far better explanation than my stiff fingers are likely to type without trouble

https://en.wikipedia.org/wiki/S.M.A.R.T.

But anyway the reason I’m concerned is because I had a No-boot situation two weeks ago which forced me to switch to a "Clone"
and yesterday I overwrote the entire SSD with a new image from my cloned drive…

For understandable reasons I’m a bit nervous about failures, but I missed
the speed and response of the SSD, so until I buy a new 240-256gb SSD
my end of day routine will include running off a new Cloned Image of the SSD.
After switching to a new SSD drive I will switch back to my slightly less paranoid weekly image making routine…

The drive I’m looking at is the Intel 730 series 240.
The ONLY reason I didn’t order one a couple weeks back when Newegg had them for $109 was I had lost my CC and was waiting for a replacement… I have hopes they’ll make it cheap again for the father’s day sale

Thanks AllandeGroot, I will look into the URL

Glad my reply helped Marty

Though I should have said “I’m not Albert…”

:bigsmile:

But as for your drive: sometimes it IS hard for S.M.A.R.T. to tell you what part of the drive caused an issue you encounter. If your drive indeed failed to respond (and it wasn’t some fluke, or some other part of the system), then maybe aging has gotten to it.

In that case, I’d say your plan to image is probably worth it. Compared to random results reported for other people’s Kingston drives, your values aren’t all that alarming, so just keep tabs. If it ever begins to freeze during casual use (or if it repeatedly misses BIOS detection), then it’s time to perform the painstaking image restoration to a new drive.

Fixed! :slight_smile:

It has never missed bios detection, though it did fail to start…

and even booting off the Win7 prox64 installation disc and doing a startup repair did not fix the situation.

I had to mount a cloned image from one of my backups over it to get it working again, but my personal policy is that if a drive fails ONCE as a system drive, I immediately make plans to replace it…

Well I no longer care very much about the Kingston 120Gb SSD…

Friday Newegg had the Intel 240Gb 730 series SSD on sale again $124, not the best price they’ve sold them for, but…)

I just finished migrating to it and even on my older (DDR2/C2Q system) it is noticeably faster…

It should last a couple years, which is what I most care about anyway…
