With hard disks, I could see reading the compressed version from disk and decompressing giving you the bytes faster than reading the uncompressed version. With SSDs that advantage likely went away.
replyI would guess to save on installed size?
replyIt's not about size or file count or disk space consumed. The question is about why would you require the extra overhead of playing the compressed version which involves decompressing it on the fly in some way, versus just playing the already decompressed version.
replyIn this case it was stated that both the compressed and decompressed versions live side by side. So there is no install size saved.
