How many reads/writes does your NVMe SSD('s) have

[P4-630]

Bought: January 2019:

 

[TheLostSwede]

OS drive since last year some time.

Game drive since a couple of months ago.

How do i check this under linux?

Curious to check my NVMe drive.

1) OS/boot, all apps and a few games drive (~55% full) for about 3 months now...

 

[P4-630]

General storage, a lot of games intalled, page file, drive (~70% full) for over 3 years.

Thats not an NVMe drive and it doesn't show the reads.
Was curious about reads as well.

Sorry I will remove it... reads not accessible for the SATA one.

No problem but was just curious about it!

I understand it now...
You do have strangely a lot reads compared to others so far.

EDIT: typo(s)

System drive for... at least a year now?

Watching that dreaded 'Media and Data Integrity Errors' attribute with great paranoia for a few months now... thus far just the one.

I think that 1 is not really 1 in that column. Must be Hex code.

mmm, most likely not an actual number. I have no idea how to interpret those raw values. I've never seen anything other than zeroes on any of my drives though! Ever. Usually when they start counting up it's a bad sign. I can assume if it continues changing that the number it corresponds to counts up.

It's always been 0-100 when I've looked. I think it depends on the program if it converts from hexadecimal to a easy representation.

How do i check this under linux?

Curious to check my NVMe drive.

smartctl -A /dev/sdxxx

Usually works well, but some values may get misinterpreted (especially for older SSDs). My Samsung XP941 is always weird with SMART. Ever since I bought it, it's WLC is stuck at 91, and on Linux always reported as 51.
I'm not even sure how to check Total BW on it, but over the past 5 or so years I can safely put it in a ballpark of over 20TBW, but way under the cautionary threshold for MLC.

And here's my SX8200 which has been abused over the past 12 months on the dot. With this tempo this TLC will last for... 30-40 more years?...

Thanks for the instructions, dude!

So: anything out of the ordinary, other than "unsafe shutdowns"?

Admittedly, I haven't used my NVMe drive all that much yet. It spends most of its day sitting idle because I'm too lazy to redo how my disks are setup. Honestly, I probably won't until I build a new machine and redesign how I want everything to work. I need to figure out how dm-cache works so I can throw an SSD in front of my RAID for caching before I do that though.

X58 = means i can only use Samsung 950 PRO with out a mod bios or third party software like duet to boot on a NVMe SSD. So that is for now, the NVMe SSD i have.

 

[toyo]

I'm surprised, only 2 people (at a glance) have more than 10TB written? So many with new SSDs? Or just not writing anything to them?
I got 10TB written on my 850 Evo just from 4-5 games installed and keeping the browser profile on it, which will write 7-10GB day.
On the 970 Evo Plus I bought maybe 2 months ago I wrote a TB just from a few initial benchmarks, before and after installing a heatsink, and normal OS usage - which on average writes 4-8GB/day with ease.
And that's with 2 HDDs to take the brunt of most games and some apps.

I mean 1 in hex is... 1

How about my SSD from 2013?

 

[tabascosauz]

Is it bad that I seem to have an irrational fear of filling up my OS drive, regardless of how big it is? Everything big always goes on my 1TB Blue 3D or 750GB MX300. Still 600GB free on my SX8200 in the past 3 months since I bought it, and almost all of that is my gigantic-ass Dropbox folder.

On the other hand, my MX300 is up at just over 26TBW, which is twice as many writes as my 850 EVO, which has been in service for twice as long (more than 4 years).

 

[GamerGuy]

Here're mine, the Sabrent 256GB (OS) and the 2TB 850 QVO are new, the rest were bought pre-owned or used, before buying though these used SSD's, I wanted assurances from the sellers that TBW was less than 10 TBW.

Edit - Didn't note that this thread is about NVMe M.2 SSD's, so I'd gotten rid of my SATA SSD's pics....
