Best 2TB MLC DRAM SSDs
There are 5 2TB MLC DRAM SSDs compared here. The fastest is the Samsung 960 PRO M.2 at 3500 MB/s read at 2TB, and the highest-rated for endurance is the Samsung 860 PRO (4800 TBW). Sequential reads across the group span 530–3500 MB/s at 2TB.
Why this configuration
A 2TB MLC DRAM SSD is a legacy endurance choice. MLC stores two bits per cell instead of three, so these older drives take far more rewriting than a modern budget drive, at a much higher cost per gigabyte.
2TB is the current default for people who'd rather not think about free space for a while.
Usually chosen for: write-heavy secondary roles and keeping older machines useful.
Good fit: workstation and creative loads that hammer random I/O.

The parts, explained
2TB is today's sweet spot for large game libraries and creative work.
MLC NAND is older and costs more per gigabyte, but is very durable.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
