I im going to make a computer and i want 200GB od memory and so a friend told to to get 2 hard drives 1 80GB and 1 120GB. what would be the advantage of this and not getting 1 200GB hardrive
None that I can see.
There are definate advantages to having more than one Partion (Drive Letter) but there is no need to have them on seperate hard drives.
If it were my system I would get one drive and create two partions, one for my OS (about 20GB ) and one for evertying else. That way I can backup and restore my OS partion without losing all my other files.
