Need is a strong word lol. I definitely don’t need as much as I’ve got as I only use 20-50GB on services (Docker and TrueNAS) with the rest being used as ZFS cache. I would not have bought this much normally but I got it as a package in a PC with an RTX 3080, Xeon Gold 6150, and the RAM for $1000 CAD (750 USD ish?). No way was I passing that up.
