I would put it out there by suggesting that you probably have low standards when it comes to databases. Have you used anything else other than MongoDB and MySQL? These are basically two of the worst NoSQL and SQL implementations in existence. Recommendation: Stop following all the hype and what all the other blind sheep are doing. Regarding filesystems... yes they do. Tons of information out there about filesystems you just have to look for it. Read up about ZFS, ReFS and that should get you started.
