A surveillance hard drive is built to record video around the clock. This collection lists WD Purple and Seagate SkyHawk 3.5-inch SATA drives from 1TB up to 12TB for DVRs, NVRs and CCTV servers, plus a few general-purpose drives that are not made for recording.
Why not use a normal desktop drive?
A recorder writes video constantly, often from many cameras at once. WD says its Purple drives use AllFrame technology, optimised for write-intensive, low-bit-rate, high-stream-count workloads, to help reduce dropped frames. Seagate's SkyHawk uses ImagePerfect firmware for 24x7 recording workloads. Both families are listed with a workload rating of up to 180TB per year, which WD describes as about three times a typical desktop drive. Retail listings also quote support for up to 64 cameras, depending on the recorder and configuration.
How much storage do you need?
Storage depends on the number of cameras, resolution, compression and retention. As an illustration, one camera recording continuously at 2Mbps writes about 21.6GB a day. Eight such cameras over 30 days need about 5.2TB, so a 6TB drive suits. Motion-only recording and H.265 compression lower this, while higher resolutions raise it.
| Capacity | Typical use |
|---|---|
| 1TB to 2TB | A few cameras, short retention |
| 4TB to 6TB | Small shops and homes, 4 to 8 cameras |
| 8TB to 12TB | Larger systems, longer retention, higher resolutions |
Things to check
- Recorder limits: many recorders cap each drive at a set size (for example 4TB on some Hikvision DVR models), so check your recorder before buying a 12TB disk.
- Interface: these are 3.5-inch SATA III drives.
- Stable power: brownouts damage disks; see CCTV power supplies and UPS units.
- Not for everyday PC use: a Seagate desktop 2TB drive and a WD laptop drive in this collection are general-purpose drives, so check the listing.
