Hi, I dont know much about hardwares. I have been using a new desktop that has core i7, with 32 gb of ram!! it works great! however I need to get something new that is reliable. someone mentioned something about something called raid5 which has 5 discs and if one fails the other 4 keep all the data till you replace the 5th disc, and the data is always secure and will never get lost. can someone explain where i can buy this? or is there something even better these days? also how do i setup an automatic backup of the server everyday? do i need another server just to run that?
