I'd love to see an "enterprise grade" hard disk drive-based backup system meant to replace tape. Think about how many medias you intend to keep in rotation and your desired retention window for old backups and you can start to do a cost comparison between hard disk drive-based backup and tape. This has been a topic of discussion here before: If you feel you absolutely must use hard drives at least use 2.5 inch laptop drives, as they are designed to survive more brutal handling than "regular" hard drives. Sure, you'll get people telling you how they've had the same drive for 20 years modern drives don't show signs of being capable of such longevity. On top of that they do not use the robust technologies that are so well proven with tapes.

You figure how reliable they are as portable media.
And that is if the thing is left in one place and not shaken or dropped.
Of all the components that make up a computer the hard drive is far and away the most unreliable. Tapes are extraordinarily robust and although tape drives have a similar failure rate to top quality server grade hard drives, unlike those hard drives the critical part, the bit that holds the data, can simply be used in another drive, something not easily done with hard drive platters. Modern tape technology is extremely advanced and error resistant, with multiple interleaved copies of the data being written to the tape, complete with error detection and correction information. As for your current use of DVDs, if you are a business why are you using hobby level backup media? The choice of hard drives or tapes tends to be a little controversial and even a bit emotional but here is my opinion.
