"Page compression is an alternative way to compress your tables which is different (but similar) to the InnoDB COMPRESSED storage format. In page compression, only uncompressed pages are stored in the buffer pool. This approach differs significantly from legacy InnoDB compressed tables using row_format=compressed, where both uncompressed and compressed pages can be in the buffer pool. In page compression, pages are actually compressed just before being written to the filespace."
"Page compression can be used on any file system but is most beneficial on SSDs..."
