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.
