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

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. 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

Western Digital Purple 6TB Surveillance 3.5 Inch SATA 6 Gb/s

Caching algorithms are tuned for write-intensive, low bit rate, high stream count applications that are typical of surveillance applications. 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. 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. WD Green: son los que consumen menos, hacen menos ruido y generan menos calor, pensados para HTPC y equipos multimedia de salón.You don't have permission to access /content/dam/doc-library/en_us/assets/public/western-digital/product/internal-drives/wd-purple-hdd/spec-sheet-wd-purple-surveillance-hdd-6tb-oem.pdf million bytes, 1GB = 1 billion bytes, and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment. 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. Western Digital clasifica sus discos por colores, siendo cada color un disco pensado para cierto tipo de uso: 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.

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).The noise level is almost identical on all the models, but there are differences. The largest drives are also the loudest with a dBA rating of 25 when idle and 26 when seeking. With a weight of 750grams, the 6TB model is also the heaviest of them all.
