Hardcard is the genericized trademark for a hard disk drive, disk controller, and host adapter on an expansion card for a personal computer.
Typically a hard disk drive (HDD) installs into a drive bay; cables connect the drive to a host adapter and power source. If the personal computer lacks an available bus on a compatible host adapter, then one may have to install an adapter into an expansion slot. The Hardcard supplies its own host adapter, and doesn't require an empty drive bay.
