Darksurf Posted April 17, 2021 Share Posted April 17, 2021 I'm curious if it would be possible to store a MAX TBW for SSDs in the warranty information in the Identity drive info, then have a running comparison of what smartctl shows for nvme/ssds to show how close you are to reaching that maximum so someone would know to prepare for a replacement. You'll see after doing a smartctl -a /dev/nvme0n1 I have a "Data Units Written" of 9.67 TB. This unit has a MAX TBW of 1800. Now, this isn't my cache drive, this is my desktop. But if you're using an SSD as a cache drive, I'm sure you could see how the SSD would quickly deteriorate and fail. My cache SSD on my server is currently at 169TBW with a maximum of 530TBW before failure. Having this SSD lifespan viewable from the dashboard would be very helpful. My SSD in my server is only 1year old, but its used heavily for an open source project.
