SanDisk Extreme Portable SSD: what owners actually say
Owners report a known firmware defect that wipes data, and WD's fix leaves Mac and Linux users stranded
What owners complain about
- Data loss from firmware bug COMMON
Multiple owners report drives abruptly wiping data or becoming unmountable. One user's drive got 'wiped a couple of times.' Another lost 4 years of their kid's videos. Ars Technica and The Verge covered the issue. A user who bought 20 units for a project had 4-5 fail within months.
- Firmware fix is Windows-only COMMON
WD released a firmware update but only provided the fix tool for Windows. Mac and Linux users have no official remedy. Even users who can update describe the tool as 'very buggy' and say they can't trust the drives afterward.
- Replacement drives also fail FEW
A user whose original drive failed received a replacement from WD that also failed, meaning at least two consecutive drives failed in a short period.
- Drives becoming permanently read-only FEW
One owner describes drives that 'decide to become permanently read-only,' effectively turning into what they call 'expensive plastic bricks.' Another notes this can happen when flash reaches a low remaining lifespan.
- Destroyed trust in brand COMMON
Multiple owners express deep distrust of SanDisk/WD. One states they have 'below-zero level of trust.' Another says they will 'never forgive WD.' One prospective buyer read the reviews and chose Samsung instead.
What owners love
- Warranty service is responsive
Despite losing all trust in the product, one owner acknowledges 'the warranty service was quite good,' suggesting WD does honor replacements quickly.
- Older models are reliable
One owner with three 2TB Extreme Portables purchased 4-5 years ago reports zero issues, noting theirs are a different model number (not the affected SDSSDE81-2T00), implying earlier production runs may be fine.
- Adequate for non-critical data shuttling
The user who bought 20 units notes they are acceptable for moving data that is already backed up elsewhere, as the failures didn't cause real data loss in their workflow.
Surprising patterns
- Multiple owners initially blamed themselves for the data loss, assuming they had done something wrong, before discovering it was a widespread firmware defect affecting many users.
- The affected model appears to be a specific SKU (SDSSDE81-2T00), and owners of older or different model numbers report no issues, suggesting the problem is batch-specific rather than affecting the entire product line.
- Even users who successfully applied the firmware update say they still cannot trust the drives, indicating the fix did not restore confidence even when technically applied.
WHO SHOULD SKIP IT
Anyone storing irreplaceable data on a single drive without redundancy, especially Mac or Linux users who cannot run WD's Windows-only firmware fix tool.
