From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

sudo smartctl -a /dev/yourssdYou're looking for the Media_Wearout_Indicator which is a percentage starting at 100% and going to 0%, with 0% being no more spare sectors available and thus "failed". A very important note here, though, is that a 0% drive isn't going to always result in data loss.
Unless you have the shittiest SSD I've ever heard of or seen, it'll almost certainly just go read-only and all your data will be there, you just won't be able to write more data to the drive.
Also you'll probably be interested in the Total_LBAs_Written variable, which is (usually) going to be converted to gigabytes and will tell you how much data has been written to the drive.
Thanks for the info. It’s really useful 👍
