Best 250GB MLC DRAM SSDs
There are 52 250GB MLC DRAM SSDs compared here. The fastest is the ADATA SX9000 at 2800 MB/s read, and the highest-rated for endurance is the Samsung 860 PRO (4800 TBW). Sequential reads across the group span 400–2800 MB/s at 250GB.
Why this configuration
A 250GB 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.
250GB covers an OS and core apps with little room for a large game library.
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
250GB fits an OS plus core apps.
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.
