SLC drives have around 100,000 write cycles. Most consumer SSDs are QLC now and those have less than 1,000 write cycles. They also tend to write slower than a mechanical hard drive when the write cache gets full. Some of those drives can be modified to run in pseudo SLC mode. That trades capacity for speed and write endurance.
That’s why it’s a good idea to take a btrfs snapshot before updating or changing things. Snapshots are almost instant and sure save a lot of work if you break something.
