After installing SSD to my Macbook Pro, I want to monitor its usage.

  • Must: Show average data written per day
  • Must: Record that data
  • Should: Estimate lifespan of disk
  • It's different than HDD ones? – Braiam Mar 7 '14 at 21:54
  • @Braiam yes, because of the lifespan – Dirty-flow Mar 7 '14 at 22:08
  • What's the difference between must and should? – Franck Dernoncourt Apr 22 '14 at 22:15
  • I don't know, ask the editor ( @Oxinabox ) – Dirty-flow Apr 23 '14 at 6:15

    @FranckDernoncourt: en.wikipedia.org/wiki/MoSCoW_method Dirty-flow: Feel free to edit it all to be Must if that is what you want. I interpretted the final requirement as more of a Should than a Must, but it could be a Could have. It is a bit of a Should to me, as you can use the earlier data to do some looking up yourself -- so there are work arounds. – Lyndon White Apr 23 '14 at 6:20

Taken from SSD Health monitor? DriveDx is quite popular, although it is only a 10 day free trail though, so it is not free.

Check out DriveDx. It shows SSD Lifetime Left indicator, overall health rating, important health indicators and many other useful information about SSD. With clean and user-friendly Mac-style interface. (HDDs are supported too)

This question has also been asked on SE AskDifferent: Is there a utility for mac that shows the information of an SSD like the health etc…?. One answer suggests a free tool, smartmontools. However, it does require some coding using Xcode, unless you use the macports port (port install smartmontools)
