Page 13: Description And Features
WD Purple PR1334M Description and Features ESCRIPTION AND EATURES General Description WD Purple Surveillance Storage is built for 24/7 always-on surveillance in high- definition security systems that utilize higher hard drive bay counts and up to 64 cameras. Exclusive AllFrame 4K™ technology works with ATA streaming to reduce error pixilation and video interruptions that occur when desktop hard drives are incorrectly used as storage in security systems. - Page 14 Description and Features WD Purple PR1334M • Pre-emptive Wear Leveling (PWL) —This WD feature provides a solution for pro- tecting the recording media against mechanical wear. In cases where the drive is so busy with incoming commands that it is forced to stay in a same cylinder posi- tion for a long time, the PWL control engine initiates forced seeks so that disk lubricant maintains an even distribution and does not become depleted.
- Page 15 WD Purple PR1334M Description and Features • Power Management — The drive supports the ATA and SATA power management command set, allowing the host to reduce the power consumption of the drive by issuing a variety of power management commands.

Product Features WD Purple PR1334M SATA 6 Gb/s SATA 6 Gb/s is the next generation interface for SATA hard drives. It adds to the functionality of the SATA 1.5 Gb/s interface with the following features: Native Command Queuing (NCQ ) — server feature for performance in random I/ O transaction environments. -
Page 27: Perpendicular Magnetic Recording (Pmr)
WD Purple PR1334M Product Features Perpendicular Magnetic Recording (PMR) In perpendicular magnetic recording (PMR), the magnetization of each data bit is aligned vertically to the spinning disk, rather than longitudinally as has been the case in hard drive technology for decades. In longitudinal recording, as the bits become smaller and closer together, they experience an increasing demagnetizing field, much like two bar magnets that are placed end-to-end repel one another. -

Page 34: Staggered Spinup
Product Features WD Purple PR1334M activity indication. According to the SATA spec, “Staggered Spin-up Disable and Activity Signal shall not be enabled at the same time.” 3.18.1 Staggered Spinup When multiple disks are installed in an enclosure, it is desirable to provide a simple mechanism by which a subsystem controller can sequence hard drive initialization to minimize the current load presented during power up. -
