If I am looking at a NVMe SSD then the leading indicators are: I just checked to see what SMART attributes are reported for an OWC SATA attached SSD and there were NO pre-fail attributes reported 😡 Most of the other attributes are indicators of age. If it is over the Manufacturer's threshold the drive has failed. A non-zero value for any of these is an early warning sign, and the closer it is to the manufacturer's threshold setting the sooner it will need to be replaced. If I am considering a rotating rust (HD) drive I would look first at…Īs leading indicators of impending failure.

I have no idea what DriveDX reports, but apps such as Micromat's TechTool Pro and Drive scope that report the ACTUAL attributes and their values provide information that can enable a reasonably informed user to draw their own conclusion. Not quite! Disk Utility's, and other apps that report only the consolidated Pass/Fail are limited to reporting the manufacturer's smoke & mirrors as you called it. Volatile Memory Backup Device Failure: Y/NĪs I see it if any of the last five items is "Y" the drive should be replaced ASAP if not sooner.NVM Subsystem Reliability degraded: Y/N.Available spare space below threshold: Y/N.The available spare threshold — set by vendor.NOTE: Numbered categories are mine and not part of the standard. Newer NVMe (Non-Volatile Memory express) drives appear to have settled on a standardized set of parameters that to seem to me to tell the tale pretty succinctly. With the advent of SSDs that connect to the system and report SMART values through the SATA bus there were additional parameters added that gave a somewhat better picture if SSD health. The problem with that is manufacturers tend to set the limits such that by the time SMART reports a problem the drive has already failed. Every manufacturer has the latitude to choose which parameters to collect and report and more importantly what the failure level is for each parameter. The ID number and the parameter name are specified in the SMART standards and as you can see there are at least 199 possible parameters in the standard. The "Drive Health Indicators" are noting more and nothing less than the specific SMART parameters the manufacturer of the drive chose to have the drive report. I also found SSD reliability in the real world: Google's experience | ZDNet, which is comprehensible, at least to a degree, even by me.

While sorting through the dandruff flakes, though, I found DriveDx for $20, but 10 bucks is 10 bucks, and unlike Drive Scope, it offers a free trial, which reported the following partial results (.only an extract, but it seems to be something of a summary.

You mentioned Drive Scope in another thread, and after looking at it I wrote it off as an awfully pricey - $50 - one trick pony, but a bit of digging revealed that my old TTP 6 serial # enabled me to buy it for ONLY $30, so I reclassified it from written-off to back-burnered, and now Jon's mention of a drive having gone south - the first such mention in a considerable period of time - has got me scratching my head.
