FAQ
Yes, but it’s not recommended. Desktop drives aren’t optimized for 24/7 multi-stream recording and fail sooner under heavy loads.
Roughly 1TB per camera per month for 1080p at 24/7 recording. 4K and AI streams require more.
Yes. 5400 RPM is fine for small systems; 7200 RPM is better for multi-camera or AI setups.
Most modern NVRs support WD, Seagate, and Toshiba drives, but always check your recorder’s specifications.
Yes. AI streams generate heavier workloads. Drives like WD Purple Pro and Seagate SkyHawk AI are optimized for this.
