Magstar 3570 data cartridges were popular on IBM systems during the 1990s as high performance near-line storage. As the decade ended and Ultrium became the dominant force in tape storage there was a move away from 3570 and similar backup tape. One Altirium customer having survived the pain of migrating all of their tape hardware over to LTO Ultrium, and having retired the last of their Magstar drives were more than a bit surprised to discover that there were still 100 3570 tapes sitting in the archive and with a retention requirement of 30 years.
