Ok, currently I store all my data on my Macbook's hard drive and also back it all up on a Western Digital "My Passport" portable external hard drive. Both of these are 500 Gb which has been fine for me up until now as this has been enough space.
Now however, Im just about at 500 Gb so I need to expand my storage systems, and I dont know where to start as Im not really clued up on computers.
What I was going to do was to just buy a larger external hard drive (something like this
) and then back everything up on that and then just be selective about what I store on my laptop itself.
The problem I see with this is obviously Im not backing up all of my data, so if the external hard drive fails then I lose some data. This would mean I would have to buy two external hard drives and back everything up twice.
Because of this Im thinking about setting up a RAID array which is by the way something I know nothing about. Is this silly/overkill or the right thing to do in your opinion?
Thanks for any help or advice!
