I'm setting up a The Dude server at home for syslog collection and archiving.

What is the fastest Micro-SD that an RB433AH can handle ?

F.

I think it doesn't matter. When the rb will write to the sd, the cpu will do all the work.. Then.. If you write/read very fast, the cpu will be 100% faster.

I think you can use any SD to have this at home. I think there wont be any difference with diferent sd cards
