Things like turning off wifi and/or turning on airplane mode can make a big difference (when you’re not needing connectivity of course) The cell modem can really eat away battery life if you have a poor signal. And for my pixel tablet, turning off wifi means the battery can last for a couple weeks instead of a couple days. Heck, turning it off if you won’t be using it for more than a few hours can help too.

Same, we’re ones of dozens I’m sure but I’ve been running a mix of WD greens and Seagate barracudas in a hardware RAID5 array for over a decade. Only had 2 drive failures over the entire time with no data loss. But yeah… would advise against that if possible
