Is it true LTO-8 cannot read LTO-6?

Yes it is true. The change is from the older GMR (Giant Magneto-Resistance) heads to TMR (Tunnel Magnetoresistance Recording) heads. These heads deliver more write tracks and greater density. This increase in capacity allows for a multi-generational roadmap out to LTO-12.

Is now a good time to move to LTO-8?

LTO-8 will not read your LTO-6 media. In addition, LTO-8 drives will be far more expensive than their LTO-7 counterparts. Moving to LTO-7 now is a great way to migrate your content on LTO-5 and LTO-6 tapes to LTO-7. Also check out our pre-purchase program that provides LTO-7 drives for use until LTO-8 becomes available.

Isn’t Content Migration a huge and complex undertaking?

Not with DNAevolution V4.5, which includes a simple tape to tape migration option. NO RESTORES NECESSARY!

But how do I know that LTO-9 will read LTO-7?

The two generations of backward compatibility was broken for LTO-8 because LTO-8 drives relies entirely on Barium Ferrite tape media. Since LTO-6 supported both magnetic particle and Barium Ferrite, the compatibility issues has arisen. This is not a likely scenario for LTO-9.

What exactly is LTO-7 Cartridge formatted as an LTO-8 Type M?

New, unused LTO-7 cartridges may be formatted as LTO-8 Type M allowing them to reach a capacity of 9TB. Once a cartridge is formatted as Type M, it may not be changed back to a 6TB LTO-7 cartridge. Also, an LTO-7 formatted LTO-8 Type M cartridge can only be written and read in an LTO-8 drive; LTO-7 drives are not capable of reading LTO-8 Type M cartridges.

What does the long term roadmap look like for LTO Technology?

The LTO Program just extended their roadmap from LTO-10 to LTO-12 with LTO-12 showing 200TB per cartridge. This means that the technology behind LTO tape will continue expanding the density, performance and cost advantages for many years into the future, providing you with the assurance that your archived material will always be available.
