Best 400GB MLC SSDs
There are 4 400GB MLC SSDs compared here. The fastest is the Corsair NEUTRON NX500 at 2800 MB/s read at 400GB, and the highest-rated for endurance is the Kingston SSDNOW E100 (3906 TBW). Sequential reads across the group span 515–2800 MB/s at 400GB.
Why this configuration
A 400GB 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.
Usually chosen for: write-heavy secondary roles and keeping older machines useful.
Good fit: mainstream desktop and laptop builds.
