The first Phison S11 model uses Micron's L06B 256Gbit MLC NAND. This is the first time we've tested any product with Intel/Micron's (IMFT) new 3D MLC. At this time, the Intel DC P3520 enterprise NVMe SSD is the only retail product armed with IMFT 3D MLC.

The second reference design uses Toshiba 48-layer BiCS 2, which is similar to the NAND shipping in the new iPhone products released just a few months ago. There is not an SSD currently shipping with this flash in retail channels. Like the Micron 3D MLC, this is the first time we've tested Toshiba's 3D BiCS NAND.

Unlike the rest of the SSDs in this roundup, these two are not currently shipping with this configuration. We may see retail products appear in January, or later in 2017.
