Best 2TB PCIe 4.0 QLC SSDs
There are 18 2TB PCIe 4.0 QLC SSDs compared here. The fastest is the Patriot VP4300 Lite at 7400 MB/s read at 2TB, and the highest-rated for endurance is the Corsair Gen4 PCIe MP600 Core (900 TBW). Sequential reads across the group span 4800–7400 MB/s at 2TB.
Why this configuration
A 2TB 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.
2TB is the current default for people who'd rather not think about free space for a while.
Usually chosen for: most modern desktop and laptop builds.
Good fit: read-heavy storage — media libraries and game installs you rarely rewrite.
Look elsewhere for: heavy sustained writes or a video-editing scratch disk.
Ranked list
Speeds on this page are the manufacturer's 2TB ratings where published (18 of 18 drives), not the family headline figure. 1 of the 18 are rated slower at 2TB than at their fastest capacity. Rated writes at 2TB run 3000–6700 MB/s.

The parts, explained
2TB is today's sweet spot for large game libraries and creative work.
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 2TB?
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.
