amazon WD Purple reviews
The WD Purple 3TB is designed for surveillance purposes, and is compatible with a wide variety of digital video recorders, including high-resolution CCTV cameras, in cases of high quality requirements.
Design
Unlike conventional 3.5-inch hard drives that are only suitable for a certain period of time, the WD Purple line of hard drives is developed for surveillance devices that feature essentially continuous data recording (approximately 80 %) While the read task only accounts for about 20%.
In addition, product design is also consistent with the continuous variation of the operating environment and especially the linear correction ability, high vibration resistance should be appropriate for the movement of the device.
One of the concerns of the hard disk drive for monitoring is the vibration, especially in a system that uses multiple hard drives paired with RAID or the like, for example with DVR Equipped with up to 8 hard drives and supports up to 32 standard HD camcorders.
With the Purple hard drives, the WD is equipped with exclusive AllFrame technology and ATA data transfer optimizer for optimized video playback, minimizing fragmented images, loss of video and support for up to 32 channels simultaneously. AllFrame technology offers reliability when it comes to reviewing important images recorded in the event of a malfunction, minimizing the risks of data recording of the recording system.
IntelliSeek technology optimizes the transfer path from scratch, speeds up data location search to reduce power consumption, and reduces noise and vibration of the hard drive while operating.
In addition, low power consumption is also an important criterion for 24/7 operation monitoring equipment in high temperature environments. Specifically, the WD Purple 3TB consumes only 4.4 watts at active and decreases to 4.1 watts at idling.

Test Lab tests the WD Purple 3TB (WD30PURX) hard drive data access on the Haswell platform configuration with the Gigabyte GA-Z97X-Gaming 7 motherboard, Intel Core i7-4770K processor, Corsair Force GS SSD 240GB and Windows 7 operating system sp1.
Please note that the tests below of the Test Lab only assess the hard drive’s data access capability, but not all features, especially stable, stable and continuous performance 24/7 of WD Purple dedicated hard drive. This is also different from regular desktop hard drives, which are only suitable for use in certain time periods.
With the AS SSD Benchmark test, the maximum data access speed of a 3TB Purple 3TB drive is about 145.5 MB / sec with read and 131.5 MB / sec read data.
PCMark 05 measures the hard drive access speed in the emulation environment, which shows an application launch rate of 5.5 MB per second, virus scanning of 160.8 MB / sec, write speed of 125.8 MB / Seconds while the Windows XP boot process is 6.4 MB / sec.
With the PCMark 8 reached 1,848 points and the average speed of the hard drive was 5.96 MB per second.
On the actual speed test when copying 10GB of composite samples of various formats including HD movies, lossless music, application installation sources, and text files between the 240 GB Corsair Force GS and WD Purple 3TB via SATA 3.0 interface.
The hard drive only takes about 1 minute and 20 seconds to finish copying data to the Documents folder, system partition with an average reading speed of 128.1 MB / sec. In contrast to the recording task also with 10GB of mixed data on takes 1 minute 22 seconds, average recording speed of 125.4 MB / sec.
