Best 4TB PCIe 4.0 QLC SSDs
There are 12 4TB PCIe 4.0 QLC SSDs compared here. The fastest is the Patriot VP4300 Lite at 7400 MB/s read at 4TB, and the highest-rated for endurance is the Corsair Gen4 PCIe MP600 Core (900 TBW). Sequential reads across the group span 4900–7400 MB/s at 4TB.
Why this configuration
A 4TB PCIe 4.0 QLC SSD is a mainstream Gen4 pick. Gen4 is the current default NVMe tier: about 7,000 MB/s, widely supported, and priced for volume. Note the QLC NAND: treat this as capacity-first — excellent for storing and reading big libraries, less ideal as a constantly-rewritten scratch disk.
4TB starts to replace juggling several smaller drives.
Usually chosen for: most modern desktop and laptop builds.
Good fit: read-heavy storage — media libraries and game installs you rarely rewrite; large libraries and archives on a single drive.
Look elsewhere for: heavy sustained writes or a video-editing scratch disk.
Ranked list
Speeds on this page are the manufacturer's 4TB ratings where published (12 of 12 drives), not the family headline figure. Rated writes at 4TB run 3700–6700 MB/s.

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.
QLC NAND stores more per cell for a lower price per terabyte, but sustained writes and rated endurance are lower, so it suits read-heavy storage.
Common questions
Is QLC reliable at 4TB?
QLC is fine for typical and read-heavy use; just expect a lower rated endurance (TBW) than a comparable TLC drive, and slower writes once the SLC cache fills.
