Any recommendations for drive health apps for non S.M.A.R.T. drives?

Edit: This should be moved to Mac Apps

What non SMART drive do you have? Almost all modern drives have SMART functionality.

If you're trying to check the SMART status of an external (USB/Firewire) drive, this will not natively work on OS X. However if you install this driver and restart the machine, it should then work fine.

If this is not the case, please can you advise what model of drive you cannot get SMART readings on? From here we can see if maybe there's an OEM diagnostic application to check the health.

Thanks for the quick reply, I appreciate the in depth response. A little more information, the drive in question belongs to a colleague and it's An OWC PCIe blade. I've never owned a non SMART drive and didn't know if there were applications as straightforward as DriveDX perhaps available.

This will work to check an external ssd thru tb?

I think OWC SSD support SMART. Aren't they?

The PCIe blades don't as far as I can tell.
That's because OWC's PCIe SSDs are just two SATA 6Gbps drives sitting behind a RAID controller and SATA to PCIe bridge. SSDs with built-in hardware RAID don't usually support TRIM, SMART etc due to the RAID controller lacking support.
