  What’s TLC and SLC in this context?

    • SLC -> Single-Level Cell, i.e. 1 bit per cell
    • MLC -> Multi-Level Cell, i.e. 2 bits per cell
    • TLC -> Triple-Level Cell, i.e. 3 bits per cell
    • QLC -> Quad-Level Cell, i.e. 4 bits per cell

    The more bits per cell you store, the more dense and therefore cheaper your flash chips can be for a give capacity. The downside is that it is slower and less reliable since you have to be able to write and read exponentially more voltage states per cell, e.g. 2 states for SLC, 4 states for MLC, 8 states for TLC, etc.

      Careful with this- since MLC just means multi, I’ve seen drives marketed as “3-bit MLC”, i.e. TLC
