Best 4TB PCIe 4.0 TLC DRAM SSDs
There are 11 4TB PCIe 4.0 TLC DRAM SSDs compared here. The fastest is the Samsung 990 Pro at 7450 MB/s read at 4TB. Sequential reads across the group span 7100–7450 MB/s at 4TB.
Why this configuration
A 4TB PCIe 4.0 TLC 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.
4TB starts to replace juggling several smaller drives.
Usually chosen for: gamers and creators who want fast, dependable storage without paying the Gen5 premium.
Good fit: everyday all-rounder use, from OS drive to game library; workstation and creative loads that hammer random I/O.

The parts, explained
4TB handles big Steam libraries, video projects and archives.
PCIe 4.0 x4 delivers roughly 7,000 MB/s, the current price-to-performance sweet spot for most builds.
TLC NAND is the mainstream choice — a solid balance of endurance, speed and cost.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
