Raw NAND types:

"LC" means "Level Cell;" wherein, "S," "M," "T," and "Q" stand for "Single," "Multi," "Triple," and "Quad," respectively.

SLC:

  • The fastest NAND flash memory in terms of reading and writing

  • The longest lifespan and charge cycle of flash memory

  • Most accurate and stable of the NAND flash types

  • The most expensive type of NAND flash

  • Generally unavailable to consumers

MLC:

  • Lower production cost and larger SSD capacities

  • More stable than the following raw NAND types

  • Not as durable and reliable as SLC SSDs

TLC:

  • Even lower production cost

  • Much shorter lifespan compared to the above

  • Slower compared to the above

QLC:

  • Greater capacity for the price compared to the above

  • Roughly equivalent to TLC in terms of speed and longevity

SATA and NVMe:

M.2 is a form factor, not an interfacing specification. M.2 form factor SSDs will utilize either SATA or NVMe as an interfacing specification. SATA III is limited to 6 Gb/s; whereas, NVMe is limited to 64 Gb/s (assuming PCIe 3.0 x4) and 128 Gb/s (assuming PCIe 4.0 x4). Of course, such a storage medium that can take advantage of these magnitudes of bandwidth do not yet exist in the consumer market (an exception would be RAM disks, but those don't apply to the M.2 form factor.

TL;DR:

M.2 is just a slot. SATA and NVMe are the protocols this slot can utilize. There is no performance difference between an M.2 SATA III SSD and a 2.5" SATA III SSD.
