 ExpressionEngine also supports database, Memcached, and Redis caching drivers. You can set which driver is being used in the control panel or via the [cache_driver](general/system-configuration-overrides.md#cache_driver) config override. [Memcached](general/system-configuration-overrides.md#memcached) and [Redis](general/system-configuration-overrides.md#redis) server information can also be set in `config.php`, otherwise ExpressionEngine will try to connect to the default respective ports on localhost.
 
-The database driver stores cache rows in `{db_prefix}cache` (for example `exp_cache`), which can reduce filesystem I/O but adds read/write load to your database server. For higher-throughput workloads, Memcached or Redis are generally better choices.

 A [backup driver](general/system-configuration-overrides.md#cache_driver_backup) can also be specified in the case your primary driver is unavailable. By default, the backup driver is the file driver and it's likely the best failover option due to its reliability, but the backup driver is configurable.
