from the purx series to purz - 4K ALLFRAME TECHNOLOGY

Improve performance with AllFrame technology

WD Purple video surveillance hard drives are equipped with the new AllFrame 4K technology that works with ATA streaming to reduce frame loss, improve playback and increase the number of supported drive bays. AllFrame reduces video interruptions that occur when desktop hard drives are misused as security system archives. Missed frames and lost images are a serious problem when an event occurs and images need to be retrieved. WD Purple with AllFrame offers you the security you need and you expect when you need to review video surveillance footage.
