Also all of these are minimum requirements. They don't actually imply much, except about the state of technology when the statement was written. Flash has been improving very quickly on all axes.

And yet there are still people who will post about the good old days and the evils of MLC, as if current SSDs were not demonstrably better in every way.

  • They aren't. Write endurance is significantly lower than SLC, it's just compensated for by lots of write leveling.

    • More precisely, endurance and retention become exponentially lower with each additional bit stored per cell, while capacity only increases multiplicatively.

    • They are better. SLC is improving as much as MLC. The ratio of speed, durability, and capacity is the same between SLC/MLC/TLC, but modern MLC is faster and more durable than 5-year-old SLC.
