Internal Hard Drive Western Digital Purple Surveillance WD22PURZ 3.5" 2TB

Western Digital Purple WD22PURZ 2TB Internal Hard Drive

The WD22PURZ is a 2TB internal hard drive from the Western Digital WD Purple Surveillance series, designed for video recording in security systems. It comes in the 3.5-inch format with a SATA 6Gb/s interface, a 5400 RPM class spindle speed and a 256MB cache. The 2TB figure is the manufacturer's nominal capacity in decimal units; operating systems usually display a smaller value because they count in binary units.

The series is rated for a workload of up to 180 TB per year and includes AllFrame technology, which helps reduce dropped frames and interruptions in recordings.

The drive suits continuous 24/7 recording in NVR and DVR systems, at home, in businesses and in surveillance setups, and is not intended as an ordinary workstation drive. The drive connects with a SATA data cable and a standard SATA power connector, and it can be installed in any computer or enclosure with a 3.5-inch bay. The SATA 6Gb/s interface is backward compatible with older SATA connections. Before installing it in a NAS or server, check the system manufacturer's compatibility list and back up any existing data.
