I have four 2 TB drives in my PC. They currently have about 5.5 TB of data on them. I want to move them to a server and build a raid 5 array. If I buy 2 more drives and move all my data to 3 drives. Can I build a raid 5 with three drives, and add the other three drives to it after migrating the data to the new array?
Also, Is raid 5 the most efficient and economical route to go?
