Best 2TB MLC SSDs
There are 6 2TB MLC 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 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: mainstream desktop and laptop builds.
