Sample System for Storage and Delivery of Digital Audio/Images

(all prices are in US dollars)

  • Total storage (3TB) cost (as of April 2007): $28,000
  • Web server with 3TB x 2: $22,050
  • HP Ultrium 920 8-slots 400/800GB 80MB/s 288GB/hr (native) $4760
  • 30 Ultrium/LTO 3 tapes x $47: $1410 (5-6 copies)
  • UPS, extra hard disks, extra media: $1556

Change in strategy: No more DVD backups. Two mirrored servers.

The basic premise of this configuration is the assumption that most of the data on this server will not change much once the digitization process is complete, thus the use of DVDs for long-term storage and relatively small number of tapes for backup. These specifications, however, will constantly change, for example, 400GB Ultrium/LTO tapes are already available.

Basic cost of storage media:

  • $0.28/GB (hard disk) $0.11/GB(LTO-3 tape) $0.05/GB (DVD) 2007/04
  • $0.54/GB (hard disk) $0.18/GB(LTO-3 tape) $0.06/GB (DVD) 2006/04
  • $0.71/GB (hard disk) $0.23/GB(Ultrium tape) $0.09/GB (DVD) 2005/04
