Is there a way for me to check my SSD's TBW?

[bungusboy81]

I have a prebuilt, and of course, since I have a prebuilt, the SSD's name is a bunch of moonrunes, so when I search it up on google to find out, it has about 1000 results about half of which are probably in some martian language and are about like car insurance or some stupid shit. Is there a program that I can use to check the TBW of my SSD?

Thank you in advance!

You can usually check how much was written with things like crystaldiskinfo or hwinfo, but if you're after the spec then no other than finding a spec sheet for that SSD.

Use CrystalDiskInfo to tell you the specific SSD you have and how much data has been written to the drive.

When you have the specific model number it says there, you can look up the drive online and hopefully find the datasheet for this drive.

 

Otherwise, can you post the model number of the drive you have?

I downloaded crystaldiskinfo and the moonrunes it spat at me were: "SAMSUNG MZALQ256HAJD-000L1"

This is the Samsung PM991: https://www.ebay.co.uk/itm/Samsung-PM991-M2-2242-PCIE-NVMe-SSD-MZ-ALQ2560-MZALQ256HAJD-000L1-Laptop-/294029949838

(The label shows the modelnr. you mentiond and PM991)

 

Samsung doesn't publish very many specs on this model though.

Seems like it's using TLC tech though and with Samsung drives, it's pretty typical those have 150TBW per 250GB of storage.

Yes, you can. For the people running running Linux you will need to install smartmontools on a Debian based distro so that we can use the smartctl command. Here is a one liner that you should be able put into the terminal to get the TBW.

 

$  sudo smartctl -A /dev/<Device Name> | grep "Data Units Written" | awk '{print $5$6}' | tr -d []

 

Example: In my case I ran and got

$ sudo smartctl -A /dev/nvme0 | grep "Data Units Written" | awk '{print $5$6}' | tr -d []
