Hello. I'll say my current setting and I'll say what I want. I currently have a Macbook with a 160GB hard drive and a 250GB drive for Time Machine and another 250GB drive for extra files. What I want is some good storage that is future proof, plus a backup of that. So I'm thinking of giving one of my 250GB drives to my mom and leave the Time Machine USB drive on my desk for when I have the macbook on my desk and I'd like to have a 1TB drive connected to the router so I can access movie files from anywhere on the house on the wireless house. Also, another 1TB drive on the same router for backup of the first 1TB drive. Some people told me something about RAID - that I could "RAID" the two drives together so any information I add to one is added to the other, therefore a perfect backup solution. I'd like some info about RAID, options of good future proof drives, and your opinions on my choice of storage. Thanks.
