Wd Purple hard wheels are designed for video surveillance systems

WD, the Western Digital division, introduced the Purple hard line of hard drives, which are intended for use in video surveillance systems, numbering up to 32 cameras.

The drives made at the 3.5-inch form factor are connected to the computer through the Serial ATA 3 interface.0 with a bandwidth of up to 6 Gbit/s. The volume of the buffer is 64 MB, the capacity is 1, 2, 3 or 4 TB. Hard drives can be used in configurations numbering up to eight drives.

The WD Purple series applies the proprietary technology of Allframe technology, which works with the set of processing commands of the ATA protocol in order to reduce the loss of personnel, improve reproduction and increase the number of supported disk compartments. Allframe technology reduces the number of interruptions in records that often arise when using ordinary drives for computers in security systems.

The manufacturer notes that the Intelliseek system implemented in WD Purple Wind Purple calculates the optimal search time, which «helps to reduce the level of energy consumption, noise and vibration, due to which ordinary drives for computers wear out faster and fail».

The hard drives are provided with a 3-year limited warranty in all countries. The cost depending on the capacity is from 90 to 200 US dollars. WD Purple discs have already begun.
