I think bzip would be a good ballpark estimate to the HW compression
in lto tape drives.

I have an LTO2 tape that is used only for a specific dataset that is
very compressible. Currently I it has 3TB on a

Great, thanks for that! That's what I thought but I'

The 6.25TB is only an estimate. If you have non compressible data you
will get close to 2.5 TB of space on your tape. If you have all text
files you may fit 15 TB on a single tape..

Hey folks,
I see that LTO 6 holds 2.5T data per tape, or 6.25T compressed.
I've never used HW compression before so am wondering whether its
performance is variable like SW compression. i.e. depends on the
file contents just what kind of compression ratio you'll get.
And also how reliable is i
