Hard Disk Drive (HDD) controllers are pieces of computer hardware that connect directly to the motherboard allowing you to add more hard drives to your system by hooking them up via the HDD controller. This can be for a number of reasons such as increasing the storage size, hard-drive mirroring or for hot-swapping where a drive can be removed without powering the system down. The controller features its own processor which allows you to bypass the motherboard's own limitations on controlling hard drives. Some HDD controllers allow the use of RAID (redundant array of independent disks) features that provide either higher speeds or more reliability.
A simple disk array controller may be integrated with a host bus adapter (HBA) to form a single adapter to easily fit inside a computer. These additional add-in cards allow you to add more IDE or Serial ATA drives to your system to give you more storage capacity. Some of these cards also allow the use of RAID thus increasing the performance and data security.

A simple disk array controller may be integrated with a host bus adapter (HBA) to form a single adapter to easily fit inside a computer. These cards allow the use of SCSI drives within a system that does not usually have SCSI ports. The RAID controllers allow the use of the various types of RAID when used with multiple hard-drives thus increasing the performance and data security.
