    Drive Health is indicating normal, yet I have a notification of Spare Block Remaining issue on my SSD. What does this indicate? No issues otherwise.

    Its end of life it seems. They use different names than the SMART standard I think.

    Its normal for cells(thus sectors) to go bad. When this happens the SSD automagically remaps them to somewhere else in the spares pool. You've got 0 spares left so any cell the goes bad just causes data loss.


    BUT, I think either
    A) that data is wrong
    B) You've had something absolutely HAMMMERING that drive for months.

    4526 PB written....4.526EB. I'm fairly sure thats impossible.....

    4526328081 - Being generous and giving it 400MB/s constant writes thats 130970 days of non stop writes. Get a better diagnostic suite.

    .....or maybe even switch the computer off while travelling back in time :D How are those figures even possible?

    Ran Crystal Disc & from what I can see, not much more info. Here "Remaining life threshold "5" what ever that means, Health indicated as 96%- Good. I disabled Superfetch when I fitted the drive. All stable with no issues, hmm...
