HPE LTO Ultrium 4 data cartridges support all HPE StorageWorks and non HPE Ultrium tape devices. Assuming 2:1 compression, the latest fourth Generation products minimize interruption to network and SAN backup by being capable of protecting 864GB/hour of data and storing up to 1.6 TB on one piece of media (double the capacity of HPE LTO3 Ultrium tapes). HP''s Non-Custom Labeled Data Cartridges allow customers to receive labeled data cartridges fast because no customization process is required. These products are perfect for customers that require labeled media but do not need to define the exact sequence printed on each label. Each HPE Non-Custom Labeled Data Cartridge will have a unique, pre-defined barcode sequence printed on each label (no duplicate codes).
