Yeah I can’t argue with the usenet fees but all three of my index sites I’ve had no issues with their free version so long as you do go wild and download ten terabytes in a night. I’ve actually had better luck with the selection compared to torrenting, pretty much is there in all of the popular resolutions. The only thing I have finding is some of the obscure adult swim shows but I can’t find them on my private trackers either.
Raid doesnt even protect against bit rot either. It doesn’t matter how many disks you write to even in a raid one array you are still vulnerable. Unless you have a high end raid card that does block level checksuming your raid array will not go back and verify previously written to data is still correct. If it does have checksuming it still isn’t smart enough to know which drive is the is correct and will lock the array in the best case.
