Be sure your NVR accepts 3.5-inch internal drives and decide between internal or external solutions based on your setup.

Mount the drive in a compatible 3.5-inch bay or use a properly powered external enclosure. Use the correct SATA interface and secure cabling; keep the drive away from vibrations and within the recommended temperature range. Regularly check drive health through your NVR software and apply firmware updates when available.

A 4TB drive can suit small to medium setups, depending on camera count, resolution, and retention. Increasing retention or adding cameras will consume more space, so plan accordingly. WD Purple is built for high-write, continuous operation, helping maintain performance as the drive fills.
