SQLite, a popular database management system, has been found to be faster than direct filesystem writes in certain situations. According to tests run on Android devices, SQLite can perform write operations up to 35% faster than the filesystem when transactions are disabled and synchronous mode is set to OFF. Additionally, SQLite is generally faster than direct-to-disk writes on Windows when anti-virus protection is turned on.
