What is the exact difference between the QLC (quad-level cells) and TLC (triple-level cell) storage types? Which is more recommendable? Which is faster?

The speed of the QVO from QLC is much slower (70-100mb/s according to benchmarks). The 500mb/s is only achieved thanks to an mlc cache, but this only accelerates until it is full, approx. 1-2 min transfer time. Sufficient for small files. Lifetime is greatly reduced. The price is not justified, you get sshdd performance and reliability for a lot of money. The EVO series is recommended.

This is about the storage density.
You can find a good explanation under the following link.

It influences the lifetime (how often it can be written)

Speed should be similar for both.
