If it’s a Mac then it’s not the CPU that’s doing the encryption for the internal drive. Macs have separate hardware for that, the CPU can’t even get the key.

Macs have encryption in hardware in the dma channel for their built-in drives (Intel Macs with T2 and all ARM Macs), so the overhead is negligible on the internal ssd. Macs actually don’t even have unencrypted internal drives anymore. The filevault toggle only affects whether the volume encryption key stored in the secure enclave is itself encrypted or not.

Older Macs and external drives are a different story of course.

I’d go mad too if someone tried to train me on AI created data all the time…

My understanding is that if an instance suddenly dies, all the federated instances that subscribe to its communities will still have the text content because they store copies locally. So knowledge should not just go away. Media is a different story though.

I think new posts/comments in those communities would then not federate at all anymore since the host instance would not acknowledge them. So the communities turn into isolated local ones.

If the host instance comes back and the communities are re-created, they’ll be empty on the host instance but I think other instances won’t delete the old content unless explicitly requested.
