Re: [Avid-L2] Re: LTO access time?

Compression doesn't really apply to our application. It's based on what is
effectively Zip compression. It is relevant for business use where files are
usually uncompressed and largely text, so a 2:1 compression ratio is
realistic. For video files we'd get no benefit from compression. Ignore the
compressed size entirely when considering video or other already compressed
binary file formats.
