It doesn't look like a firmware fix will be enough.
SanDisk Extreme Pro Failures Result From Design and Manufacturing Flaws, Says Data Recovery Firm::A data recovery specialist from Austria uncovers several possible hardware reasons for the Extreme Pro’s failures.
This is a bit more detailed, technical explanation:
Industry experts from Attingo, a seasoned data recovery firm that confronts faulty SanDisk Extreme Pro SSDs on a weekly basis, have shed light on the intricate nature of the defects. The company has pinpointed that the resistors deployed in these drives are mismatched with the circuit boards they sit on, leading to precarious connections that under duress, break. The frailty is exacerbated by an unstable soldering material known to bubble and crack, although it is still under debate whether one or both elements are the primary catalyst for the defects.

I don’t care WHY they failed.
My issue is that after they discovered the failure, they continued selling it, nearly a year after the fact.

Mismatched as in incorrect resistance?
As in size. E.g. a 1206 resistor on a 0603 pad or vice versa.
