I have Exos drives (which are probably more enterprise 24/7), and I don’t really see a difference to normal everyday consumer use HDDs. They’re just loud af, which is honestly a huge drawback
That said, I’ve only ever had one HDD fail, and these have only been running 24/7 for about a year
If they’re not that much more, might be worth it for the NAS drives. Just depends how important your data is and how much you value peace of mind
Best Buy 0% credit card? Idk what’s in Ireland though lol
