The size of preserving digital archives is now reaching the order of petascale (1×10¹⁵), exascale (1×10¹⁸) and will approach zettascale (1×10²¹) capacities in the foreseeable future. A strategy to move low activity, but potentially valuable archival data to the optimal storage tier immediately yields the greatest cost savings. Archive storage growth and requirements have no foreseeable limits and could demand a new deep archive storage tier in the next few years. Unless a new archival technology arrives, the numerous improvements in tape have made it the clear-cut optimal data archiving choice for the foreseeable future.
