Many _serious_ reports of problems there, across many models and firmware revisions. It's an ongoing problem, and WD is ignoring it entirely.
- jeffbee 1y agoIt's just a brand. The SN770 shares nothing technical with, for example, the SN8100.
- justinclift 1y agoWell, "the brand" is ignoring the problems across several SSD models.
- wtallis 1y agoThe reports in that thread you linked to are clustered around several models that do have substantial shared technology: a DRAMless design using an in-house SanDisk controller, and difficulties arise with the NVMe Host Memory Buffer feature that is only applicable to DRAMless drives. But the high-end SanDisk drives aren't DRAMless, and the SN8100 in particular doesn't even use an in-house SanDisk controller.
- mananaysiempre 1y agoThanks! I see that the people reporting problems with the (DRAMless) SN770 there also report no problems with the SN850X, but that might not be indicative either way—AFAIU the 8TB SN850X has somewhat different internals compared to its lower-capacity brethren. (It does put Framework’s decision to ship SN770—now SN7100—SSDs in their laptops as standard in an unfavourable light.)
