WD Purple™ drives feature a workload rating of up to 180TB/year 2 - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems. The Seagate Skyhawk AI HDD is designed with “AI'' firmware to improve the drive’s ability to handle recording, video analysis, and GPU analytics workloads. This includes up to 64 HD video streams and 32 AI streams with zero dropped frames. This is combined with a robust warranty, including a high workload rate and Seagate’s three-year data recovery service. through 3TB (WD30PURZ) support up to eight bays; 3TB (WD33PURZ) and 4TB and above support up to 16 bays.
However, as opposed to storing music, documents, or other files, the CCTV DVR Hard Drive will store images, videos, and even audio. million bytes, 1GB = 1 billion bytes, and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment. For performance, HDDs are also often gauged by rotations per minute (RPM), which is usually a direct indicator of performance. The RPM value impacts sequential transfers as well as random access latency. Lower RPM drives tend to be quieter and more efficient, while higher RPM drives have better performance. There are also variable RPM drives that try to achieve the best of both worlds. Power draw, heat, and noise are factors related to performance.Finding the best Hard Drive within your budget can be tough. But with the variety out there, there is often an option that works for your price range.

It is important to be aware of the drive’s form factor, with 3.5” being the most common for the best HDDs (this is the only type we cover). If you need 2.5”, your options are more limited, especially for capacity. Otherwise, your computer case’s ability to house a certain number of 3.5” drives might be your primary limitation.

SSHDdrives offer faster software and gameloading/installationtimes plus overall faster transfer speeds. Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
