The majority of HDD failures happen in the first 1-2 years (see Backblaze data). I have a NAS that has the same 5 drives running since 2013 and in all that time those disks were not spinning for maybe 3 weeks total.
That said I assume that any drive can fail at any time and anything I don’t want to lose has 2 backup copies, e.g. stuff I am working on on my PC gets copied to that NAS, that in turn backs it up online.
