Best 1.92TB DRAM-less SSDs
There are 5 1.92TB DRAM-less SSDs compared here. The fastest is the Mushkin SCORPION DELUXE at 2165 MB/s read at 1.92TB, and the highest-rated for endurance is the ADATA SU650 (1120 TBW). Sequential reads across the group span 500–2165 MB/s at 1.92TB.
Why this configuration
A 1.92TB DRAM-less SSD is the value shortlist. Dropping the DRAM chip takes cost out of the drive, and Host Memory Buffer borrows a little system RAM to cover most of the gap. Gaming and everyday use barely notice; sustained random writes do.
Usually chosen for: budget builds, game libraries and second drives.
Good fit: value builds and gaming where cost per gigabyte matters.
Look elsewhere for: databases, virtual machines and other sustained random-write workloads.
Ranked list
Speeds on this page are the manufacturer's 1.92TB ratings where published (5 of 5 drives), not the family headline figure. Rated writes at 1.92TB run 420–1990 MB/s.

The parts, explained
DRAM-less drives use the Host Memory Buffer (HMB) instead — cheaper, and fine for everyday use and gaming, with a small penalty under heavy random writes.
Common questions
Is a DRAM-less 1.92TB SSD good enough?
For gaming and everyday use, yes — HMB covers those workloads well. If you run sustained heavy random writes (databases, VMs), a drive with a DRAM cache stays more consistent.
