    I remember reading an interesting take on the 20TB drives when they came out - the impact of drive failure skyrockets with large density drives.

    Back with 2TB drives, you could fit 60-70 Blu-ray rips. If that drive dies (without backups/RAID), you’ll be hurting but not as bad as if you have a filled 20TB with 600-700 rips. Plus, even with RAID, the rebuild time increases with density, and for 20TB drives you could be waiting a week for rebuild.

    I like the idea of higher density drives, but in my opinion they only really make sense in large drive arrays where you can spread the data over dozens and dozens of replicated drives.

      I do miss being able to back up my 8 GB drive onto five bucks’ worth of CD-Rs.

      I do not miss having only 8 GB to work with.

      Luckily the ones that are considering buying this have that or something similar and/or extensive backups.
