WD Purple 8TB Surveillance Internal Hard Drive, 3.5 inch SATA 6Gb/s, 256MB Cache, AllFrame Technology, 180TB/Year Workload Rate, Supports Up to 64 HD Cameras, 1 Million Hours MTBF, 3-Year Warranty (WD85PURZ)
The WD Purple 8TB (WD85PURZ) is a 3.5 inch internal hard drive built specifically for video surveillance recorders that run 24 hours a day, seven days a week. Unlike a desktop drive, it is rated for a 180TB per year workload and a 1 million hour MTBF, and Western Digital AllFrame technology works with ATA streaming to cut frame loss and keep playback smooth when several cameras write at once. It connects over SATA 6Gb/s with a 256MB cache, sustains transfers of up to 215MB/s, and supports systems with up to 64 HD single-stream cameras. Power draw stays low at 5.3W while reading or writing, and the drive is backed by a 3-year limited warranty. PC PARK supplies it for DVR, NVR and CCTV installations across Saudi Arabia.

Frequently Asked Questions
How is the WD Purple different from a normal desktop hard drive? It is engineered for continuous 24/7 writing rather than an office duty cycle. It carries a 180TB per year workload rating, a 1 million hour MTBF and AllFrame technology that reduces dropped frames when several camera streams record at once.
How many cameras can the WD85PURZ handle? Western Digital rates the drive for systems with up to 64 HD single-stream cameras, subject to what your DVR or NVR itself supports.
How much footage will 8TB hold? It depends on resolution, frame rate, compression and how many cameras record. As a rough guide, 8TB stores several weeks of continuous recording from a handful of HD cameras using H.265 compression.
Can I use the WD Purple in a normal PC? Yes, it is a standard 3.5 inch SATA drive and will work in a desktop. It is tuned for streaming writes rather than random desktop workloads, so a WD Blue or Black drive is usually a better fit for a general-purpose PC.
What interface and cache does it use? A SATA 6Gb/s interface with a 256MB cache, with host transfers of up to 215MB/s.
How much power does it use? About 5.3W while reading or writing, 4.7W at idle and 0.4W in standby, which keeps recorder heat and running costs low.
What warranty does it carry? Western Digital provides a 3-year limited warranty, and PC PARK supports the warranty locally in Saudi Arabia.
