I everybody, I would like to ask you some advices about external hatd drive. In my home network I have 1 mac mini and 2 macbook pro. Every machine has it's own internal storage with an indipendent external disk for time machine backup. I'm running out of space and I would like to buy an external network disk (RAID???) to centralize the storage of all my medias (movies, pictures, songs...) and maybe reachable out of my home network (I have a static ip). I will use some 500 gb hd that i already own fot TM backups for every machine. Any suggestion? WD? LACIE? Names, models etc... Every advice will be appreciate!!!!!!
