Western Digital WD_BLACK SN770
45 out of 100 medium confidence 13 reviews
The WD_BLACK SN770 2TB offers excellent read speeds and is praised for gaming and secondary storage, but several users report serious reliability issues, including boot loops, BIOS failures, and partition corruption, especially when used as a Windows OS drive. While some recommend it for its performance, others advise against it for primary use and suggest alternatives like the SN850X. The lack of DRAM and potential thermal throttling are also noted concerns.
