If I remember correctly, the pro drives used 2 bit which is MLC and not 1 bit which is SLC. This one uses 3 bit so it should be TLC but I could be wrong.

The 980 Pro is an MLC drive, which is why it is so cheap.

Well Samsung's marketing says it's MLC but it's actually TLC hence the bits. 3 bit = TLC, 2 bit = MLC and 1 bit = SLC.

Even the reviews are saying the same thing.

"The NAND storage store methodology for the 980 Pro is TLC based (so three bits per cell written), and not MLC as opposed to the documentation."

TLC is the cheap one, true MLC has been the expensive one in the consumer targetted drives like the 970 Pro as those used 2 bit MLC.
