I want to use my Pi as a NAS for my iTunes library, Time Machine backups and Home Theatre.
I am planning to use a small SD card to boot and put the OS on another storage medium. But something that I haven’t figured out is what storage medium. I can use an external HD, a USB flash drive, or (don’t know if it’s possible) Ethernet storage. I can either use one, or all of them based on their performance and capacity limits.
So, which storage medium(s) is/are ideal from a capacity as well as performance standpoint?
Keep in mind that it is inevitable that at some point of time, all three would be accessed at the same time.
