Yes, your Samsung ssd compares very favorably to what my Crucial MX500 ssd was doing before I intervened with the selftests regime. Your Samsung has dropped to 94% while your pc has written 68 TB to it. My MX500 dropped to 93% in its first 6 months, during which the pc wrote about 6.2 TB. The bigger issue was that, during the last 6 weeks of those 6 months, it dropped from 95% to 93% while the pc wrote only 528 GB... and the problem was getting worse: during the last 3 weeks of those 6 months it dropped from 94% to 93% while the pc wrote only 128 GB.Exactly. 5 years old.
Purchased Aug 6 2016, running 24/7 as the OS drive since then.
Your question about ssds that "actually died early" is overly narrow. MX500 ssds have been on the market for only a few years. My MX500 is too new to fit your narrow category, but it's obvious that at the rate it was losing life (before I intervened with selftests) it would eventually suffer a very early death, far short of its 180 TB duration spec.
