I have 2 x 250GB Samsung 840 SSDs as cache drives in my unraid server. That’s been their job for about 5 years. Before that, they were in a RAID 0 on my main desktop for many years. I just looked at their attributes in Unraid and they’ve been online for 15y 7d for one of them and 15y 11m and their remaining wear level is 65% and 69% respectively. One of those drives may fill and clear 3+ times a day where other days it could be 25-50%, so I’d consider at least that one as heavy use. They other is mostly just app data and lower transfer volume.

Those are old tech drives that are small capacity and have a lot of transfers on them in my arr setup and manual process before that. To still have more than 50% life is a testament to how good the wear leveling is and how the write count isn’t all that important for 99% of applications.
