I have a Kingston 480Gb SSD, it’s lasted for 3 years already, its count of reallocation events has been steadily increasing since I have purchased it and it’s now at 17, I have no idea of how many reallocations before it runs out of spare blocks.
smartctl
says it has 4% of lifetime left, but I have only written about 5TB of data to it, and the manufacturer claims the 480Gb version can handle up to 160TB of lifetime writes.
So basically sounds like it’s either still brand new or close to death and I dont know which it is.
I already have a spare SSD to back up my data, but I wonder if I should wait for this one to die before cloning it. If I understand correctly, when SSDs die they become read-only instead of unreadable, so the risk of data loss low, or at least I hope so.
here’s the result from smartctl.
$ sudo smartctl -a /dev/sda
