SanDisk Extreme Pro Failures Result From Design and Manufacturing Flaws, Says Data Recovery Firm | Tom's Hardware
The problem is that data on SanDisk's portable SSDs ``Extreme Pro'' and ``Extreme Pro V2'' suddenly disappears, or the SSD itself becomes unusable. After receiving the report, SanDisk acknowledged that there was a problem with the 4TB model and promised to release a firmware update. However, similar problems have occurred with the 2TB and 3TB models, but these have been ignored.

However, Markus Häfele of the data recovery company Attingo told the news site futurezone, ``It's not a firmware problem, it's a design and structure problem.'' Attingo, who has been in the data recovery business for 25 years, receives Extreme Pro at least once a week.
What Mr. Hafele points out is a problem with the entire soldering process of the SSD.
First of all, air bubbles are introduced during the soldering process used to attach components to the circuit board, making it easier to remove the solder. Additionally, because the component is large relative to the intended layout on the board, it is mounted at a high position, and there is little contact with the pad that should normally be in contact with the component, resulting in a small solder joint. It seems that it is in a state where it breaks and comes off.
This is the state of the SSD in question shown by Attingo. You can see that the solder is white and bubbling. In addition to problems with the temperature and humidity of the working environment, Mr. Hafele also raises the possibility that the quality of the solder is low to begin with.
In addition, when futurezone contacted the manufacturer Western Digital about this matter, they replied, ``In the spring of 2023, we recognized that there was a problem with this model and distributed a firmware update that fixed the problem.'' There was no response regarding the deficiencies.
Mr. Häfele points out that Western Digital is aware of the design and construction flaws, as improved models have been released that are firmly fixed by adding epoxy resin to the defective areas.
