It is important to match the generation of the tape with your drive so as to ensure good performance and reliability. Working with the incorrect generation results in read/write errors or utter mechanical breakdown. An analysis of your alternatives according to capacity requirements and legacy hardware limitations is provided below.
-
Current Generations (LTO-8/9): The lto tape cartridges have huge capacity (up to 18TB native in LTO-9), which is specifically designed to back up entire data centers, archives of high-resolution video, and large database warehouses.
-
Legacy Support (LTO-4/5/6): Select these data tape cartridges when you have to recover some older archives or when you have to maintain compatibility with current library hardware that is not yet ready to be replaced.
-
WORM Technology: To guarantee that financial records, legal documents, or medical files cannot be altered, deleted, or overwritten once written, select storage tape cartridges with the capability of Write Once, Read Many.
Summing everything up, never buy your drive without checking its generation. By investing in the right LTO class today, you not only save yourself the headaches of data migration in the future but also maximize the lifespan of your archive.
