MySQL or SQLite, they're the great source for storing your accounts data and other storing things instead of some ordinary library to write files and reading files which is very slow as compared to the loading of rows and fields from the SQL table. Don't use MySQL or SQLite if you have no idea about it because you can easily mess it up and would take time to solve your issues because SQL is a different language. y_ini or any other file saving/loading system is working as a library which is made in PAWN and it's having quite different setup so you obviously won't get that much performance as compared to using MySQL (through plugin) and SQLite (SA-MP have it built-in - no plugins required).
