Why? WD seems to be able to make fast QLC drives with equivalent endurance to TLC.
It probably has a larger SLC cache than most QLC drives to get decent performance. A write endurance of 300 drive writes is not great though.
That's for the worst case scenario. In larger sizes the QLC models have higher write endurance than the TLC ones. Also 300 writes is pretty typical for 500GB TLC drives. Not saying it's great but it's been the norm for this size for years.
AFAIK, there is no need for dedicated SLC cache. They can run multi-level flash as single-level and as a result they can configure how much of the QLC is used as "SLC" cache. And yeah, there's probably plenty.
The Samsung 990 PRO 2TB has 600 overwrites.
Thats one of the best consumer grade ssd out there today.
300 is fine for most people.
