Unfortunately, this work might not get there, consumer SATA drives basically never even report errors to the controlling computer until the damage is already done (they just correct them, and say the wrote with no error, how helpful of them!).

I think NVMe disks are a bit better, and, to be honest, if you need spinning disks SAS disks are usually less than $50 more than SATA disks. I guess you do need the HBA though.

(Note, ime even enterprise SATA disks don't tend to report errors very well)

I thought this work was about filesystem errors, not about storage device errors, which are covered by the support for SMART in various places, although I think for GNOME you have to install smart-notifier to get SMART notifications. Filesystem errors can be caused be Linux kernel bugs or by storage device errors or silent storage device corruption (which happened to me), so they are a superset of storage device errors.
