Silicon Motion SM2258 Technical Preview With Micron 3D TLC NAND

[Guest]

The SMI SM2258 is the next small controller that will make a big impact on the entry-level and mainstream SSD market. The controller is already shipping with 2D NAND, but now it supports the new IMFT 3D NAND that will power several new SSDs.

Low endurance 3-bit per cell?!? That is 32 bit right?!

What does this mean, in reallity? It will outperform the high-end samsung 850 pro drives?

It's pretty cool, but I really don't see the point. S-ATA SSDs are a dead end, the future belongs to M.2 and U.2.

tlc have 3-bit cells. there are 8 levels of states (not sure if these are volts or amps), each level give a binary number between 000 and 111, so can represent 3 independent bits. To have 2 independent bits, you only need to reliably distinguish 4 states, which is obviously easier, but the 66% less memory per density.
