Sorry but it’s obvious you don’t have kids. You need to know when and how much formula your baby had to not overfeed them. You need to know what a toddler ate if he comes home and throws up/has diarrhea/gets a sudden rash. You need to know when his diaper was changed so you know if you need to change it again when you get home. Etc. You really need that info, and people working in daycare absolutely don’t ballpark this as they need to know it as well and they have 18 other kids to take care of so they can’t remember it all.

Anecdotal, but mine (a 4TB one) is running fine (knocks on wood) for 5+ years now. It’s in my server and doesn’t spin down. Low power usage as well. Very happy with it…
