    Hello everyone,

    I own a 64GB Surface Pro which was exchanged for a new one in August by Microsoft Tech Service. I have had to reinstall the OS three times (once was my fault and the other two times was because while updating it shut off due to a faulty charger -now exchanged as well). I have had to reinstall all my programs and updates twice because of that (three times if we include the first time I installed them).

    Having seen CrystalDiskInfo it states that I have made 1428GB in "Total Host Writes" and 763GB in "Total Host Reads". I would like to know if these values are normal for a surface which is not even 3 months old, and if my SSD's life may have been affected.

    Thank you very much :)

    Welcome to the forum

    When asking about reads and writes there is no such thing as normal. Everyone will have a different number depending on what they are doing with Windows and the programs installed.

    With that said, your figures don't look out of line at all.

    There is a theoretical limit on writes for SSDs before cells become unusable. However I have worked with SSDs since 2009 on both personal computers and enterprise storage arrays and i have yet to see even the busiest systems reach that limit.

    Thank you very much for your reply :)

    I know there are no normal values as it completely depends on the user, but the surface is 3 months old and has not had really intense use, don't you think it is too much taking into account that it has had a moderate use (VS 2013 programming with source on the MicroSD and media playback from USB drives). Should I be worried by having used so many write cycles already? Is my SSD degraded?

    Thanks

    No, I don't see those figures as abnormal, not even for 3 months of use. Just applying the initial updates would have caused quite a few in just an hour. I wouldn't worry about any degradation at all.

    All those reads and writes are spread over all the cells on the SSD so any one cell has had a minimal number of reads/writes.
