I am wondering if there is a utility for the mac that allows you to see the details of an SSD like the health of the drive, TBW (total bites written), how many running hours etc... In researching for an app of such a kind I found (SSDLife) for windows? It looks like to me that a program like this would be exactly what I would need. The most important information that I need to know about is the TBW (total bites written) on the drive. Because I have heard that once an SSD drive reaches a certain amount of writes it becomes a read only drive, so this information would be invaluable to me.

If you're OK with Command Line utilities, you can always use You would need XCode to compile them from source (unless someone here knows binary distribution for Mac OSX), but if I remember correctly I had no issues compiling the package. I have an OCZ SSD retrofitted into my MBP 15" mid-2010 and I can use To give you an idea, here's the example output:
The exact parameters and stats shown for your SSD might vary, but as it's a free tool, you can try and see for yourself! |

I have owned a MacBook Pro Retina since August 2012 and it gets modest use, with mainly web browsing and online video streaming as the main uses. As the DriveDX report shows, the SSD is rated at 90% after 3.5 years of use. My MACs seem to last forever, with an iMac 27" from 2009 still running fine - though I maxed out the memory and replaced the regular hard drive with an SSD this year... Still cranking along after 6 years, so I can see why people may be worried about wearout, but like most things with Macs.. you seem to pay them big money up front and once you have paid the premium, their hardware choices really seem to provide long life for the average mac user... |

This isn't a software recommendation (I see there are already a few posted), but more of a tip. Although SSDs do have a shorter "life" than HDDs, it is still by far a longer life than you'd reach with normal conditions. Your SSD will outlast its own desirability and that of the computer it's in, i.e. by the time it craps out, you probably would have wanted to upgrade your computer anyway. Moral of the story: don't worry about it. From OCZ's FAQ
