LTO is Open format

Proprietary storage systems don’t give you a lot of options when you want to transfer data. They can lock you into a system that can be more expensive and lacking innovation.
That’s why LTO specifications are open format, designed for interoperability from among multiple competing vendors. These vendors submit their products to compatibility testing to ensure vendor functionality so that an LTO tape from one vendor can be used on a drive provided by another. It’s become the de-facto standard for medium-tier storage needs.

Compatible with prior 2 generations

Most importantly, the LTO format ensures that your investment today will continue to pay off for years to come. LTO specifications provide backwards compatibility to read/write with previous generations. Current-generation LTO drives are able to read tapes from two generations prior and are able to write to tapes from the prior generation. With a published roadmap, LTO technology allows you to better forecast how to address your future technology as you address your needs today.

LTFS makes tape like a file system

And with the Linear Tape File System (LTFS), LTO tape options are more compatible than ever before. There’s no need for a proprietary system to locate that document or video file that you’re searching for. LTFS makes it easy and simple.  It’s open source and open standard, meaning that it’s broadly available regardless of which brand of LTO tape that you’re using.

Conclusion

Today, LTO technology provides the confidence that the file you save can be accessed by a broad range of partners for years to come. That’s the LTO difference
