Applications, trade-offs and selection guide

Controller for your storage design

Decide whether you need hardware RAID or direct OS access to disks. Verify HBA or passthrough behavior for the exact model and firmware. A family name or port count does not establish that capability for every controller.

Cache, cables and battery matter

Verify internal/external ports, card form and riser support. If write cache is used, check its protection method and required battery or capacitor. A controller without the right cables and backplane is not a complete configuration.
