The published specs don't tell us how many layers of NAND there are, but they do claim the 2TB is only 1.8X the write performance of the 500GB and 1.125X the 1T

The published specs don't tell us how many layers of NAND there are, but they do claim the 2TB is only 1.8X the write performance of the 500GB and 1.125X the 1TB. Not the 4X you'd speculated.
If you have a QN322, feel free to provide benchmark results.
- wtallis 4y agoNAND layers is another question entirely: that's about how many layers of memory cells each die has, not about how the dies are packaged together. And of course the performance specs for the 2TB don't show it being 4x faster than the 500GB model: those specs are for peak performance when using the SLC cache. Consumer SSD specs almost never list post-cache performance. I don't have one of the drive in question, but unlike you I actually know enough about how these things work to know what performance claims are plausible or not.
