Best 1TB PCIe 4.0 DRAM SSDs
There are 35 1TB PCIe 4.0 DRAM SSDs compared here. The fastest is the Samsung 990 Pro at 7450 MB/s read at 1TB, and the highest-rated for endurance is the ADATA XPG GAMMIX S50 (3600 TBW). Sequential reads across the group span 3900–7450 MB/s at 1TB.
Why this configuration
A 1TB PCIe 4.0 DRAM SSD is the mainstream high-performance pick. Gen4 paired with a DRAM cache delivers close-to-flagship real-world speed and stays consistent under sustained load, for far less than a Gen5 drive.
1TB is the capacity most single-drive builds settle on.
Usually chosen for: gamers and creators who want fast, dependable storage without paying the Gen5 premium.
Good fit: workstation and creative loads that hammer random I/O.

The parts, explained
1TB is the mainstream single-drive capacity.
PCIe 4.0 x4 delivers roughly 7,000 MB/s, the current price-to-performance sweet spot for most builds.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
