MyISAM Storage Engine: 


·  MyISAM tables are very fast if insertion queries are lesser than select queries made. It has the built-in indexing option which will fasten the query's response time than any other table type


When to use:


·  Use MyISAM table type where select statements (preferably more with where clauses) are made often than Insert/Update Statements.


·  Use MyISAM table type if you want lesser disk space than any other mysql storage engine.


InnoDB Storage Engine:


·         InnoDB tables are transaction enabled mysql storage engine type.


·         An InnoDB table allows you to do concurrent read & write statements as it supports row level locking.


When to Use:

·         Use InnoDB table type where insert & update statements are made often than select statements.
