That was sort of what I was wondering, if the NAND controller has some extra Apple Stuff(tm) beyond standard ECC.

- wtallis 3y agoThe standard for SSDs goes far beyond the ECC used on DRAM. Every SSD controller designer will have their own proprietary scheme, often a simple and fast BCH that falls back on LDPC for higher error rates. The exact codeword sizes and other parameters of the codes are vendor-specific.
