Best 4TB PCIe 4.0 TLC DRAM-less SSDs
There are 19 4TB PCIe 4.0 TLC DRAM-less SSDs compared here. The fastest is the Biwin NV7400 at 7450 MB/s read at 4TB. Sequential reads across the group span 5000–7450 MB/s at 4TB.
Why this configuration
A 4TB PCIe 4.0 TLC DRAM-less SSD is the value-performance sweet spot. You keep Gen4's high sequential speed — the part game loading and everyday tasks actually use — while dropping the DRAM chip (HMB fills in) trims the price.
4TB starts to replace juggling several smaller drives.
Usually chosen for: value-minded gamers and upgraders chasing NVMe speed at the lowest sensible cost.
Good fit: everyday all-rounder use, from OS drive to game library; value builds and gaming where cost per gigabyte matters.
Look elsewhere for: databases, virtual machines and other sustained random-write workloads.

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.
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 4TB 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.
