We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Is there a solution for caching structure of the directory and for metadata of all the files? For example a have a huge collection of small files on my HDD and i want to "cache" all of it to an SSD in a way that i will store only information about the directory and necessary metadata, but when i want to actually access data from the file it will redirect to HDD

If you determined that whatever caching the OS does is insufficient then you can try ZFS with a special vdev for metadata (though beware, it's not cache).
