Why LTO-10 Fell Short On Speed And Backward Compatibility
Blocks & Files, Tuesday, July 29th, 2025
LTO-10 tape was an advance on LTO-9 but not as much as expected with no increase in data I/O speed and loss of backward compatibility. We look at why this took place.
Before turning to LTO-10's detailed characteristics, we'll sketch out how LTO-9 works in a simplistic way to provide the background for the LTO-10 development. An LTO-9 tape is laid out longitudinally with 8,960 data tracks in four data bands, separated and defined by five servo bands. These tracks and bands run the length of the tape ribbon.
