WD WDBGKN0040HNC overview

  • 1Description

The 4TB Purple 3.5" Surveillance Internal Retail Hard Drive (WD40PURX) from Western Digital is a 3.5" SATA drive with a data transfer rate of 6 Gb/s that is designed to withstand the stresses placed on it in a 24/7 surveillance system. With support for up to 32 high-definition surveillance cameras, this 4TB hard drive can hold a large amount of data and gives you the ability to easily upgrade and expand your security system.

A 64MB cache helps to ensure uninterrupted data transfers and the drive's 300,000 load/unload cycles, combined with its 1 million hours MTBF helps ensure the drive will have a strong operational life. This drive is compatible with both Windows and Macintosh operating systems and includes mounting screws.

Surveillance-Class Drive
WD Purple surveillance-class storage has been tested to be compatible in a wide-range of security systems. These drives are designed to replace standard desktop drives that were not designed for the 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.
Surveillance Storage
The WD Purple Surveillance Hard Drive is designed for high temperature, always-on, surveillance security systems to ensure reliability and quality video play back when you need it most.
Improve Performance with AllFrame
This WD Purple Surveillance-class hard drive is equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increase the number of drive bays supported. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage can be a problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence you should expect when it's time to play back and review critical surveillance footage.
Optimized Performance for Up to 32 Cameras
With support for up to 32 high-definition surveillance cameras, this WD Purple hard drive gives you the flexibility to upgrade and expand your security system in the future.
IntelliPower Rotational Speed
In terms of speed, this drive operates using WD's IntelliPower rotational speed. This means that the rpm speed of the drive depends on the operations being performed. If the drive is performing mostly sequential reads and writes, its speed will be increased as compared to if it were performing mostly random mode operations. This 6TB drive also features a 64MB cache helps ensure uninterrupted data transfers.
Low Power Consumption
With integrated IntelliSeek technology, this WD Purple drive calculates the optimum seek speed which lowers power consumption, noise and vibration that can damage and cause drives to wear out more quickly.
Windows and Mac Compatible
Compatible with Windows 8, 7, Vista, and XP
Compatible with Mac OS X Mountain Lion, Lion, and Snow Leopard

Please bear in mind that Windows XP does not support drives with capacities greater than 2TB. Compatibility may vary depending on user's hardware configuration and operating system

    WD WDBGKN0040HNC reviews

    4TB Purple 3.5" Surveillance Internal Retail Hard Drive (WD40PURX) is rated 4.9 out of 5 by 9.
    Rated 5 out of 5 by from Great Choice for Lorex Surveillance NVR The drive was immediately recognized by the Lorex NVR, formatting took about 4 minutes, and the drive was online a few seconds after that. I wanted to extend service life of the existing 2TB drive that came with the NVR so the recorder has two drives now (2TB+4TB, both WD). Our NVR has two drive bays and the drive arrived with mounting screws so the upgrade was a breeze. While one drive records, the other one can spin down and sleep, and this is precisely what I wanted to accomplish. This WD drive is so quiet that at first I thought it was not running, but it is. Awesome! Highly recommended.

    Rated 5 out of 5 by from BEST hard drives! I use ONLY these drives in CCTV recorders. Rated for the constant 24/7/365 use, these drives are the BEST! I ordered 10 and got them QUICK! Total cost was less than I could have gotten them locally at an electronic retailer, but of course they didn't have any in any of their 5 Los Angeles locations!!!! B&H Photo is the BEST!!!!

    Rated 4 out of 5 by from No issues I put two of these hard drives into a Raid 1 array for surveillance recording. I've had no issues at all. Durability is obviously the most important factor when looking at a drive ... and it's hard to really say since I haven't had these for too long ... but they're working great.

    Rated 5 out of 5 by from 4TB WD Purple Surveillance Hard Drives work great. Would re Replaced single 3TB drive in a Q-See NVR with four 4TB drives. Installed without a hitch and came up on the screen when I booted up the NVR. Has been working perfectly since installation and has extended my storage time dramatically.

    Rated 5 out of 5 by from Good buy Used as a secondary drive in a Lorex camera system after primary drive had filled. Installed for a couple weeks now and no issues - working great. Primary drive is full so all writes are going to this drive.

    Rated 5 out of 5 by from Works as expected replaced a 2TB to increase continuous recording time-seems to be working great so far.
