Best PCIe 3.0 QLC SSDs
There are 11 PCIe 3.0 QLC SSDs compared here. The fastest is the Intel INTEL® SSD 670P SERIES at 3500 MB/s read, and the highest-rated for endurance is the Fuzedrive P200 (3600 TBW). Sequential reads across the group span 1800–3500 MB/s.
Why this configuration
A PCIe 3.0 QLC SSD is an affordable NVMe step up from SATA. Gen3 is roughly six times SATA's throughput yet often costs little more, making it the easy default for a first NVMe drive or a laptop that only supports Gen3. Note the QLC NAND: treat this as capacity-first — excellent for storing and reading big libraries, less ideal as a constantly-rewritten scratch disk.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
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.

The parts, explained
PCIe 3.0 x4 reaches about 3,500 MB/s — plenty for everyday use and gaming, and cheaper than Gen4.
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 these?
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.
