Sandisk SSD: what owners actually say
SanDisk SSDs are dogged by a recurring firmware-related failure that owners say the company hasn't actually fixed, even after replacement drives and promised firmware updates.
What owners complain about
- Abrupt drive failures with data loss COMMON
Multiple commenters reference SanDisk Extreme SSDs failing abruptly and wiping data. One case involved a journalist losing 3TB on a replacement drive sent by the company after the original failed.
- Firmware fix doesn't work COMMON
SanDisk issued a firmware update in late May claiming to fix the failures, but owners report the supposedly fixed drives — including replacements sent by WD — continue to fail.
- Company trying to suppress the issue SOME
Multiple commenters accuse SanDisk/WD of attempting to keep the failure problem quiet rather than addressing it transparently, with one calling it a known fault the company 'is doing its best not to keep quiet.'
- Class action lawsuit filed FEW
A class action lawsuit has been filed against SanDisk/WD over the Extreme Pro SSD defect litigation, linked directly in comments.
- Contaminated flash scandal FEW
A commenter reports that SanDisk/Toshiba produced around 6 exabytes of contaminated flash, then attempted to clean and sell the contaminated stock rather than discard it, which is speculated to underpin quality issues.
What owners love
- Historically reputable brand
Several commenters note SanDisk was once a go-to recommendation for SSDs and flash drives, though they emphasize this is no longer the case and the brand is 'skating by on brand recognition.'
- General SSD speed advantage acknowledged
Stack Exchange commenters note that moving from HDD to any SSD, including SanDisk, produces a noticeable speed improvement, particularly for small file access, though differences between specific SSD brands are described as slight.
Surprising patterns
- Owners are so frustrated that multiple commenters explicitly recommend avoiding ALL SanDisk and WD products, not just the affected Extreme models, as a trust issue.
- A recurring suggestion from experienced owners is to buy 'new old stock' of SSD models 1-3 years old that have proven reliable, rather than current-generation drives, because all major manufacturers cycle through quality issues.
- The community discussion around SanDisk's failures repeatedly derailed into arguments about RAID topologies and backup strategies, frustrating commenters who wanted to focus on the manufacturer's accountability.
WHO SHOULD SKIP IT
Anyone storing irreplaceable data on a single drive without redundant backups should avoid SanDisk SSDs entirely, given the documented pattern of abrupt failures even on replacement units that were supposed to be fixed.
