Checking "Health" of SSDs

While SSDs are known for lasting longer than HDDs, with the recent issue about SSDs in M1-based Macs, maybe it would be good to have a way of checking on the status of SSDs. Well, I just saw this on the Macworld site:

Apparently it can also be used with Catalina.

Micromat's TechTool Pro 13 and Drive-Scope provide the same critical information (Available spares, available spare threshold, percentage used, percentage remaining, over temperature threshold exceeded, reliability degraded, backup device failure)) in a graphic format on NvME drives and the equivalent S.M.A.R.T. data on HDs. NOTE: Both products work well on Intel Macs but neither product is "certified" for M1 Macs. On an M1 Mac TinkerTool TechTool Pro will run the report, but DriveScope crashes on launch.

If we knew what it was we were doing, it wouldn't be called research, would it?

Cool! I have Tech Tool Pro, so will need to look at it further.

But the post from Macworld does provide a free way to get the information.

It is free if you don't count the 29.34GigaBytes of disk space used by Xcode. I would think that is a very significant chunk of disk space on your clean, lean, machine just to check SSD wear.

Yeah, that's just crazy! Since I have Tech Tool Pro (and another SMART Utility program), I'll just use it.

And yes, my Macs are lean, mean, and clean! Makes them run with no issues. Many folks are clueless about that.
