Adding Different Size Hard Drives to RAID Arrays? Possible?
Hey Im trying to build a media server that will continually grow in size but not nessecarily with the same size HDs. Now I want some sort of redunancy as this will grow in to 2TB + and well if it completley crashes its a giant pain in the ass.
Currently I have 3 x 300gb Seagate drives and was originally going to create a software Linux RAID 5 array thinking I could add HDs. Now I know you can add HDs to RAID 5 but I have no clue how, the other problem is that I probably wont continue to add only 300gb HDs as the larger size ones continue to get cheaper and cheaper but once again RAID 5 is only as good as the smallest HD multiplied by the number of HDs so adding a larger 400gb is a waste of space.
So what should I do? I want some redundacy (Parity information seems to be the cheapest solution), also all the HDs under one drive letter, not 7 or 8, and the ability to add different size HDs later down the road.
