Yeah it’s a fun ride.I run a cluster and the storage is replicated and distributed among them. 3/6 of my disks were QLC. One disk went bad super early and caused a bad latency but the other 5 disks kept performance up for the most part. Once I found out it was hardware I went with an enterprise SSD with a a 3 DWPD rating (drive wipe per day) and those beasts are so good. TLC m.2s seem to be okay too but I don’t think I’ll ever touch QLC again.
I highly doubt this is true.
