Right. I forgot about the parity part. Then what's the best solution for what I want to to do? Just keep doing what I am doing? My method is this. My server has a total of 6 USB ports. It has 4 in the back and two in the front. One in the front is used for a dongle so I can have a wireless keyboard and mouse. That leaves 5 USB ports for other drives. One is being used by a small drive for my music drive.
Now, I have 4 4TB drives connected in the back of machine and I still have the one free in front. What I am doing is using two of the drives as main media drives, and two for backup. So when I rip a movie, I copy it to my main drive and to the backup drive. I have my media software (Jriver) only looking into my two main drives. So once all of those drives are full, I can pull the backup drives out and put in two more drives. This again would be one for main media and one for backup. When that is done, I will do it one more time. I would get two HD's and plug one in the back of my machine and one in the front. Once they are both full I will just pull out the backup and that would be it. I would have 20TB of media ready to go. But, that would be it. I would have no more USB inputs for any more HD's.
That's why I was hoping I could use a RAID system. I though then I could get more space used per USB ports plus at the same time, simplify my backup plan. But if it does not work that way, then maybe I will just keep doing what I am doing and hope the space lasts me a long time. Otherwise I would look into that HUB. When I pick a movie, only that drive with that movie would be active so maybe the performance level would not drop that much. We shall see. I still have more space to go so I will see how much my remaining media takes up.
Thanks again for your help
. It is very much appreciated. Do you have any ideas that might work for what I want to do? Can I do what I want to do. I thought I have seen people with really big HD like 20T worth of data so I know it's possible. Would Raid one be what I really want? If so, do you think bigger HD's are safer. If I got a Raid one system with 2 5TB
drives, would that still leave me with 9TB(4.5 for new media and 4.5 for backup)? Does RAID one use a parity bit? Or would I have 10TB. 5TB for new data and 5TB for the backup.
