I'm looking to build a storage bank for time machine backups of my macs (imac and 2 macbook pros) and to provide space for all my various other files. They would include music, movies, photos, documents and large project files (ie final cut pro projects that I am currently working on). I would like to setup the hardrives so that they are redundant and there is a backup of each one just I case one fails. They would ideally be connected to my airport extreme to share over my network. I estimate that 2-3 tb would be enough room if the redundant drives are not included. 3tb would be ideal as it would give me about a tb of extra space for my photo, music, fcpx projects, and movie collection to grow. Just out of curiosity, could I build an array of drives that are redundant and also have varying sized hdds? For example I use 2tb for time machine backups and have 500gb for movies, photos, fcpx projects ect. With all of that being said, where do you guys recommend that I buy my drives from and which drives exactly? I looked around newegg and tiger direct earlier but wasn't sure exactly which drives to chose. Is it even a good time to be buying hdds? I know earlier in the year there was a storm that damaged a couple major hdd producer factories, making prices go up. Are they still high from that? I'm not in a hurry to get this storage array built and would be willing to wait until later this year if prices will be lower then.
