Wow, that must be quite expensive! You said the files alone are a few PB. So at least 2PB / 8 servers ~= 250TB per server, which would probably put each server at > 20k $ (unless you’re putting it together with duct tape and scraps, but even then the disks will cost a ton).
Hey,
Not exactly. Attachments are only fetched from Discord as the user requests them. This means that the vast majority of attachments are never stored on my server. Right now, I only have about 280TB of attachments locally on my own infrastructure. You can see more stats here: https://searchcord.io/about
Thanks for your question!
