I have had a 2013 MBA since last October (i.e. about 7 months), it has a 512GB Samsung SSD and I use it daily and quite heavily (it's my primary and only computer). I used DriveDX to check the SSD's health and it reports that its "wear leveling count" is at 90% (see attachment). Is it a normal value? Does it mean I am 10% into the drive's lifecycle, or something worse or better? Thank you very much.
