Best 500GB QLC SSDs
There are 20 500GB QLC SSDs compared here. The fastest is the Patriot VP4300 Lite at 7400 MB/s read at 500GB, and the highest-rated for endurance is the Intel INTEL® SSD 670P SERIES (740 TBW). Sequential reads across the group span 520–7400 MB/s at 500GB.
Why this configuration
A 500GB QLC SSD is a capacity-per-dollar configuration. QLC packs more gigabytes per dollar in exchange for lower rated endurance.
500GB is a sensible OS-plus-a-few-games size.
Usually chosen for: bulk storage and read-heavy media libraries.
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 500GB ratings where published (14 of 20 drives), not the family headline figure. 1 of the 20 are rated slower at 500GB than at their fastest capacity. Rated writes at 500GB run 510–6700 MB/s.

The parts, explained
500GB is a comfortable OS-and-games starting point.
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 500GB?
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.
