I've come across several articles stating TLC SSDs have better reliability and longer lifespan than QLC SSDs. However, they don't specify how much more reliable they are. I'm aware the real-world lifespan of an SSD is dependent on many factors, but a TLC drive can potentially be double the price of QLC, making this reliability difference important to quantify.
How much of a difference is there between the average reliability and lifespan of a TLC SSD vs a QLC SSD? Is there significant difference in failure rate or number of writes between TLC and QLC?
