SSD failures on low time machines - DriveDx fail - DiskUtil pass

[myuserid08]

Hello
I manage around 120 MacBooks. Over the past 4 months we've had 15-20 returned from leavers/upgrades. Around 50% have failed the tests on DriveDx.
When running first aid through Disk Utility the drive passes - but DriveDx shows as a fail under available spare blocks.

Attached is an example - this machine has only 33 hours powered on time!

Should I be scrapping these machines or could it be a false positive. There does seem to be an unusual failure rate if DriveDx is to be believed.

I manage about 150 macs currently, and all of them have either pure SSD storage, fusion drives, or home-built fusion drives. I've seen zero real-world failures on the original Apple-supplied solid state storage. Plenty of issues of course with the spinning-portion of Fusion drives failing, etc. And plenty (well, a handful) of total failures of third-party SSDs, but all of our MacBook Airs and MacBook Pros (retina models), from 2013 models to present, continue to function perfectly with the original Apple-sourced internal solid-state storage. Of course, I've never once bothered to test any of them like you have, since I've had no reason to suspect any storage-related issues, but if you wanted me to *guess* I'm thinking you are seeing false positives. You could try a different utility. My understanding (and I could be wrong) is that DiskDrill is considered reasonably good?

I think this is likely a false positive. I'm thinking that it's possible that ID3 may be reporting something different or differently than what DriveDx is expecting. It would be best if you reported this to BinaryFruit so they can investigate.

Thanks - the "failures" seem to be on 2018/2019 Air's. I haven't had any issues with the Pro line.
Contacted BinaryFruit a while back and they hadn't had any other reports. I've re-opened the case.

My understanding is that they are looking at two different things. Disk Utility is looking at the health of the Directory and DriveDX the physical state of the drive, using SMART data. No conflict if one says OK and the other not, though of course there comes a point where the physical state of the drive may corrupt the Directory, but not the other way round.

now I have the same problem on my Macbook pro, did you find out if it is a bug?

Did you find the answer? Did the ssd failed or working properly? I'm a bit worried because I have the same thing

Any updates on this issue? Also seeing it on a 2019 MacBook Air.
