Western Digital Purple 6TB Surveillance 3.5 Inch SATA 6 Gb/s Hard Disk Drive with Allframe 4K Technology - 180TB/yr, 64MB Cache, 5400rpm - WD60PURZ

Product Information

WD AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications I'm using this to increase the capacity of my Swann 8580 series NVR surveillance system. It won't allow anything larger than 6 terabytes and it came with a 2 terabyte hard drive. Western Digital clasifica sus discos por colores, siendo cada color un disco pensado para cierto tipo de uso:

The drives don’t just have to be perfect for the scenario that they are to be used in, they also need to be compatible with the systems themselves. WD made sure that this was the case by working closely with industry leading chassis and chipset manufacturers. If you got an NVR system, you’ll most likely find the WD Purple on the official list of supported drives. H.265, also known as High Efficiency Video Coding (HEVC), was introduced in 2013 and is the latest video compression standard to be supported by newer NVRs, especially for 4K video support. Before selecting H.265, make sure that your DVR/NVR system supports this standard.The entire line of WD Purple drives, from 1TB up to 6TB, all feature 64MB cache and come in the same 3.5-inch form factor. WD also used their IntelliPower system that we know from such drives as the RED series, that uses variable speeds to bring the performance that is needed without excessive noise from the motors. But that is where the similarities of the drives end. The 6TB version that I’m taking a closer look at today is the best performing of them all with a sustained speed rating of 175MB/s where the 1TB model for example only is rated for 110MB/s. The drives naturally also differentiate in power consumption. The bigger the drive, the bigger the power draw, that is if the word big even applies here. The WD Purple 6TB draws 5.3W during read and write operations, 4.9W when idle, and 0.4W when in standby or sleep mode. Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations. In today’s review, I am taking a look at a mechanical hard disk, but it isn’t one that is intended for your desktop system. Western Digital created their Purple line of hard disk drives to be the perfect choice for digital video recording, network video recording, and surveillance systems. On the test bench today is the 6TB version of this WD Purple surveillance hard disk.

Next to being designed for 24/7 always-on scenarios, the WD Purple series is also designed for high-temperature environments. The temperature rating of the WD Purple, on the base casting, ranges from zero to 65 degrees Celcius when operating and -40 to 70 when non-operating. Compré el de 6TBs porque el precio por TB era el mismo que en el modelo de 4TBs y la capacidad es algo que siempre se queda corta, aunque ahora pensemos que nunca llenaremos 6TBs, en un par de años estarán llenos, pues cada vez hay mas dispositivos que graban en 4K, luego será 8K, cámaras con mas y mas megapixels... http://media.webcollage.net/rwvfp/wc/cp/18574709/module/wdc//_cp/products/1413335120504/tab-ac400f4c-4428-497b-9f34-63a3b9c75d5f/8cfae72e-fb78-49a4-accb-6f5861c122cb.mov.mp4full.mp4 With an MTBF of up to 1 million hours, this WD Purple WD64PURZ drive is engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components and support for sixteen (16) drive bays, this WD Purple drive delivers reliable operation in surveillance systems even in harsh environments. Wide Compatibility, Seamless Integration Whether you want to protect your personal assets and loved ones or monitor the business you worked hard to build, you’ll want surveillance-class storage to rely on. Not only are these drives built for 24/7 usage in environments up to 8 disks, they also come with enhanced firmware built just for this kind of operation. When it comes to surveillance, every frame counts, and every frame has to be perfect. This is especially noticeable when many cameras are using the drives simultaneously. WD’s Purple series has no trouble here and it is designed to work with up to 32 HD cameras.Este disco no es mas que un disco como cualquier otro, pero lo preferí frente a otras marcas algo mas baratas porque estos suelen tener mas fallos y por la poca diferencia de precio no merece la pena arriesgarse. Y esto no lo digo yo, podéis buscar las estadísticas de un centro de datos con miles de discos y los de marca mas barata siempre suelen fallar mas que el resto, sin entrar en modelos concretos. through 3TB (WD30PURZ) support up to eight bays; 3TB (WD33PURZ) and 4TB and above support up to 16 bays. WD Blue: son discos todo-terreno, para todo tipo de usos no específicos, su rendimiento varia en función de las RPMs que use (desde 5.400 hasta 7.200). As used for storage capacity, 1TB = WD Purple drives feature a workload rating of up to 180TB/year 2 - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems.
