I have an SSD that's around 5 years old now. It used to be in my laptop. But then I upgraded my laptop and put it in a homeserver. It still works perfectly well but from what I've read, SSDs fail suddenly without much prior indications.

Do you think I should replace it already? It's not running any super important stuff. If it dies, it'll just mean that my media servers will be down for a day, not a super big deal since I have regular backups. I feel bad creating unnecessary e-waste, so I'll love to know your experience with SSDs and how frequently do you usually replace them.

Also, if you know a tool which can help me detect remaining lifespan of an SSD, that'll be very helpful. Thanks.
