Item Value
Volume emulation type 3390-3
Number of user cylinders 3,339
Number of volumes 2,048
Total volume capacity 870 KB × 3,339 × 2,048 = 5,949,296,640 kB
5,949,296,640 KB ÷ 1,024 = 5,809,860 MB
5,809,860 MB÷ 1,024 = 5,673.70 GB
5,673.70 GB ÷ 1,024 = 5.54 TB
Estimated needed capacity At least 6 TB
