Best 1TB DRAM SSDs
There are 164 1TB DRAM SSDs compared here. The fastest is the Corsair MP700 Pro XT at 14900 MB/s read at 1TB, and the highest-rated for endurance is the Samsung 860 PRO (4800 TBW). Sequential reads across the group span 450–14900 MB/s at 1TB.
Why this configuration
A 1TB DRAM SSD is the consistency-first shortlist. An onboard DRAM cache holds the flash mapping table on the drive itself, so random performance stays steady when the workload keeps going rather than tailing off.
1TB is the capacity most single-drive builds settle on.
Usually chosen for: workstations, virtual machines and anything that writes continuously.
Good fit: workstation and creative loads that hammer random I/O.

The parts, explained
1TB is the mainstream single-drive capacity.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
