Best 3.84TB DRAM SSDs
There are 4 3.84TB DRAM SSDs compared here. The fastest is the Kingston DC450R at 560 MB/s read at 3.84TB, and the highest-rated for endurance is the Kingston DC500M (9110 TBW). Sequential reads across the group span 555–560 MB/s at 3.84TB.
Why this configuration
A 3.84TB 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.
Usually chosen for: workstations, virtual machines and anything that writes continuously.
Good fit: workstation and creative loads that hammer random I/O.
