The following storage engines are most commonly used:

MyISAM: The default MySQL plug-in storage engine, which is one of the most commonly used storage engines in the Web, data warehousing, and other application environments. Note that it is easy to change the default storage engine of the MySQL server by changing the storage_engine configuration variable.

InnoDB: For transactional applications, with many features, including acid transaction support. (Row-level lock available)

BDB: An alternative to the INNODB transaction engine that supports commit, rollback, and other transactional features.

Memory: Keep all your data in RAM and provide extremely fast access in environments where you need to quickly find references and other similar data.

Merge: Allows a MySQL DBA or developer to logically group together a series of equivalent MyISAM tables and reference them as 1 objects. Ideal for VLDB environments such as data warehousing.

Archive: Provides the perfect solution for storing and retrieving large amounts of historically, archived, or security audit information that is rarely referenced.

Federated: The ability to link multiple separate MySQL servers to create a logical database from multiple physical servers. Ideal for distributed environments or data mart environments.

Cluster/ndb:mysql's clustered database engine, especially suitable for applications with high performance lookup requirements, also requires the highest uptime and availability.

Other: The other storage engines include CSV (referencing a comma-delimited file used as a database table), blackhole (for temporary suppression of application input to the database), and the example engine, which can help with the quick creation of a custom plug-in storage engine.
