SanDisk SSD users have been grappling with persistent failures, and the root cause may be a fundamental design flaw rather than a mere firmware issue. Reports of failing SSDs and data loss prompted attention on Reddit, eventually leading to class-action lawsuits against SanDisk’s parent company, Western Digital. While initial attempts focused on a firmware fix, data recovery firm Attingo has identified potential hardware shortcomings, specifically citing inadequate soldering, oversized components, and irregular connections as contributors to the failures.
Understanding the SanDisk SSD Failures:
- Users began reporting SSD failures as early as May 2023, gaining widespread attention on Reddit and later resulting in class-action lawsuits against Western Digital in August.
- SanDisk initially attempted to address the failures with a firmware fix, but Attingo, a data recovery firm, suggests the issue lies in the hardware rather than the software.
Flawed Design and Manufacturing:
- Attingo’s analysis points to inadequate design and manufacturing as the culprits behind the failures. Weak soldering failed to secure components to the circuit board adequately.
- Oversized components led to irregular connections and overheating, creating bubbles that disrupted connection points, ultimately resulting in data loss.
Temporary Fixes and Ongoing Concerns:
- Western Digital responded to the issue with firmware updates, but this proved to be a temporary solution as the problem was more deeply rooted in the hardware.
- The company introduced new firmware along with a stronger epoxy resin in newer SSD models to address the design concerns.
No Official Statement from Western Digital:
- Despite the ongoing issues, Western Digital has not released an official statement on the matter and is not expected to address the problem in the future.
- The company, however, shared on its firmware update webpage that the addressed issue is not impacting currently shipping products.
Precautions and Backup Recommendations:
- Users relying on SanDisk SSDs are advised to consider backup options, especially for irreplaceable data. Popular cloud-based alternatives include Google One and Microsoft OneDrive.
