Surveillance-class 1 TB drive with 5400 RPM, 64 MB cache and SATA 6.0 Gb/s interface built for write-intensive security systems
The WD Purple WD10PURX is a 1TB 3.5-inch internal hard drive engineered for video surveillance systems. It uses a SATA 6.0Gb/s interface, spins at 5400 RPM and provides 64MB of cache. The drive is designed for write-intensive, low bit-rate, high stream-count workloads typical of security recording.
This drive suits installers and system integrators who need a drive rated for up to 180TB per year workload in multi-bay surveillance enclosures. It supports more than eight bays and includes TLER and ATA streaming support. Buyers wanting a general-purpose desktop drive or a drive for low-duty, intermittent access should look at something else.
The single specification that decides fit is the 180TB per year workload rate. Surveillance systems that write multiple streams around the clock need this endurance rating; workloads well below that level do not require a surveillance-class drive.

| Features | Desktop drives vs. surveillance-class storage WD Purple surveillance-class storage has been tested to be compatible in a wide-range of security systems. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.

The 180TB/year rating means the drive is built to handle continuous write streams from multiple cameras without the wear that would shorten a desktop drive's life.
The SATA 6.0Gb/s link caps the maximum burst transfer rate, but sustained throughput stays well within the 5400 RPM drive's capabilities for typical camera bit-rates.
Yes, the 26.10mm height matches the standard 3.5-inch form factor, so it mounts in any desktop or NVR bay designed for full-height drives.
