Having gradually built up my media collection to near the capacity of my 16TB external HDD, I’ve reached the point where I’ll probably need to build a RAID array to keep the collection in one place. Assuming the RAID array will be at least 32TB, I have a few questions:
-
From what I’ve read RAID arrays can help mitigate the risk of individual drives failing if extra space is allotted on the hard drives. Assuming a total capacity of 32TB, how much of that space would be reserved by the RAID array for data loss prevention?
-
Is there a certain type of hard drive I would have to use? Aside from my 16TB drive, I also have two 2 8TB drives that I’d ideally like to be able to re-use in the RAID array, but have left them in their enclosures for the time being.
-
If the hard drives in the array have different transfer speeds, does the array as a whole default to the slowest one?
-
Whether the hard drives I already have are compatible or not, what RAID enclosure and hard drives would you recommend?
