Hello, :)

I had to learn more about SSDs as we're selling them to our customers, and our goal is to maintain a 5-star rated service. So, I've learned that one particular type of memory chips called QLC is the worst of all. Here is what BARD have replied when I've asked it to compare to other types like TLC, MLC and SLC.

"QLC stands for Quad-Level Cell, and it is the latest type of flash memory used in SSDs. QLC SSDs can store four bits of data per cell, which makes them the most affordable type of SSD. However, they also have the shortest lifespan, with a write cycle endurance of up to 100 write cycles per cell."

I'm attaching as well a table that this AI has printed on the screen. Keep in mind that some people might have their QLC even for 10 years, that depends on how frequently you write and read on this drive. And, not everyone is the same :). 

So, for infrequent users, I'd say, the minimum should be TLC. But, for more frequent users a minimum should be MLC or SLC.
