The thing is SQLite handles a lot of hard problems that you might not realize you have: like “was my data actually written to the disk”
Even if you can in theory save some time with small files with sqlite, you would be back to read/write IO and userspace/kernel byte buffer switching.
And it probably wouldn't be faster than something like a mmaped file anyway (unless the SQLite Db is also mmaped).
