    Was just looking at DriveDx at the health of my SSD (128GB 2012 MacBook Pro Retina 13") - I've had this laptop just over a year, these are the stats:

    Overall Health Rating: 92%
    Power On Time: 4,010 (5 Months 17 days 2 hours)
    Power Cycles Count: 9,708

    Just wondering as I'm not a very heavy user if this is normal or not for the power cycles count?
    Thanks

    Mine's in that neighborhood and its a 2012 rMBP.

    Personally I stopped looking at it, because I was getting obsessive about it. My suggestion is to enjoy the laptop. When (or if) the time comes to replace the SSD then worry about it then. Its probably several years away at this point.

    Can you post the SMART readings from DriveDx? SMART values, especially power on time and power cycles, tend to report incorrectly.

    Mine was down to 70-something after 18 months.

    I wonder if I mine is. I went through a recent period of rebuilding and re-installing. As I mentioned mine was in the 90s when I looked a while ago.

    I've also reinstalled the OS lots. But that's only writing to 6GB of the SSD. I think DriveDX is misreporting.

    My opinion only, but I sense that whatever the program is using to determine the "Overall Health Rating", at least -some- of the point total is designed to reflect nothing more than hours of usage, power cycles, amount of storage space used, etc.

    What this means in real-life is that the rating can go down for no other reason other than that you have used the drive over an increasing period of time -- even if no other "faults" are seen or reported...

    My Macbook Pro 15" is 2 months old and this app is showing 94% health.
    I don't know if I should worry or laugh so I deleted the app :)

    So you threw it into the recycling bin and laughed manically? ;)
