From what I‘ve heard it‘s all about guarantees because SSDs have a tendency to just go bad sometimes. Some SSDs are more expensive because the manufacturer will offer a replacement for up to 5 years. You can expect these manufacturers to have better quality control too. They don‘t want to replace SSDs left and right after all.

Take this with a grain of salt because I never actually had to get an SSD replaced myself. But I would only trust a manufacturer that‘s been in business with a good reputation for 5 to 10 years. Cheap storage sounds tempting but for me it‘s not worth risking to lose my data over. Yes I make backups but still.
