1 products · A hard drive (HDD) for a recorder (such as a DVR or NVR in a surveillance camera system) is a specially designed storage device that can continuously store videos, often 24/7.

Technology: Magnetic disks that spin and a read/write head. Speed: Slower. Durability: More sensitive to shocks from moving parts. Sound level: Can produce sound and become warmer. Advantage: Lower price per GB, often much larger storage capacity.
