QLC drives are all trash. They have ok performance in bursts, but the sustained performance is terrible and the reliability is awful.
QLC means it’s storing 4 bits of information per cell. And it does this by holding a charge at 1 of 16 levels. It’s basically analog.
The only way QLC achieves decent burst performance is that they all have an SLC cache. SLC is a single bit per cell.
With the current tech, I wouldn’t go beyond TLC, which is 3 bits per cell.
