I understand that things vary greatly based upon features used. However, to the uninitiated (read: me) I have a hard tell figuring out positioning differences between RB5xx and RB1xx. The obvious physical differences aside over number of physical interfaces what is the difference? Is there some sort of general guideline? e.g. RB5xx is more suitable for applications that require >100Kpps.
Since RB153 has 5x 10/100 ports and 3x mPCI slots why would I want to buy a RB532 that actually has less 10/100 ports and mPCI slots and cost more?
I understand there's a RB532A with more memory, lets just say you don't really need additional memory.
