DanielCoffey Posted September 4, 2017 Share Posted September 4, 2017 I have had a Samsung 840PRO 256Gb since 2013 and while it still passes a SMART check, the Wear Levelling Count has left zero at last. I know these SSDs have an overprovision but how concerned should I be about the health of this SSD? In summary, we have 3240 hours, 14667 power cycles, 34 reallocated sectors, 150 Power Recoveries and 8879245966 LBAs written.

JorgeB Posted September 4, 2017 Share Posted September 4, 2017 Wear leveling count is still at 99%, the 34 is part of the count, not reallocated sectors, SSD is almost like new. Quote Link to comment
DanielCoffey Posted September 4, 2017 Author Share Posted September 4, 2017 That is good to know. I just checked the other 840PRO I bought at the same time and which has been used for Win10 gaming and it has the Wear levelling Count at 96% so that is the one which is showing more use. Five times the amount of data written too. I think I will retire the Windows one and keep the drive I showed above as an addition to the cache pool on the backup server so it can digest bigger backups at a time before filling its cache.

HellDiverUK Posted September 13, 2017 Share Posted September 13, 2017 Retire it? You still have 96%. Assuming an approximate wear of 4% per 3000 hours, you still have 72000 hours, which is 8.2 years. Worst case scenario. I think perhaps you're a little premature in retiring it. Quote Link to comment
