Don't know if it is appropriate, but you should begin to treat any media
(HDD, SSD, etc) as consumables.
You can't expect some device will work for any amount of time and won't
fail. They all fail. Even tanks fail.
Any media could fail for sooo many different reasons and nobody can
predict them all. You have to be always prepared for the moment when
that happens, basically
by asking yourself this question: "What will I do if my current disk
will fail right at this moment and there will be no possibility to
recover any data from it?"
If your answer is: "I will replace it and restore my data from backup on
another device and probably loose a day worth of work." Then you're fine.
But if your answer is: "This is not happening..This is not
happening..This is not happening.." Then it's a huge problem, and it has
nothing to do with device's reliability or type.
So stop fearing and perform regular backups.

That said, personally I can't imagine a PC without a SSD or NVMe drive
nowadays. Even more if it is a laptop.
SSDs are relatively cheap, super fast and became more reliable, than
they were a few years ago. Firmwares got better, controller ICs got better.
HDDs has their uses too and they mostly used for storage capacity, in
workstations, NAS devices and servers with RAID for redundancy.
If your fear is about warranty and RMA then buy devices from well known
brands and from your local PC hardware store. Everything else is
mitigated by backups.
