Product Information

You don't have permission to access /content/dam/doc-library/en_us/assets/public/western-digital/product/internal-drives/wd-purple-hdd/technical-ref-manual-wd-purple-hdd-6tb.pdf En mi caso, compré un Purple porque su uso va a ser almacenamiento de datos y copias de seguridad en un servidor casero que está casi siempre encendido, así que es perfecto para este uso. WD Green: son los que consumen menos, hacen menos ruido y generan menos calor, pensados para HTPC y equipos multimedia de salón. 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. 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.

WD Purple HDD - Western Digital Product Brief: WD Purple HDD - Western Digital

MJPEG is an older standard for video compression. First used in the mid 1990s, it is less efficient and is likely the more common standard for lower resolution video. WD AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applicationsMTBF specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions: workload of 90TB/year and drive temperature of 40°C. Derating of MTBF will occur above these parameters, up to 65°C drive temperature. MTBF does not predict an individual drive’s reliability and does not constitute a warranty. Single stream at 3.2Mbps (1080p, H.265, 25 fps) for WD22PURZ, WD33PURZ, WD42PURZ, WD43PURZ, WD60PURZ, WD62PURZ, WD63PURZ, WD64PURZ, WD84PURZ and 2.6Mbps (720p, H.265, 25 fps) for WD10PURZ, WD20PURZ, WD30PURZ, WD40PURZ. Results may vary depending on camera resolution, file format, frames per second, software, system settings, video quality, and other factors. 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.

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... through 3TB (WD30PURZ) support up to eight bays; 3TB (WD33PURZ) and 4TB and above support up to 16 bays. With an MTBF of up to 1 million hours 3, WD Purple™ drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components 3 and support for more than eight bays 4, WD Purple drives deliver reliable operation even in harsh environments. 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. With an MTBF of up to 1 million hours 3, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components 7 and support in storage systems with more than eight drive bays 4, WD Purple drives deliver reliable operation even in harsh environments.
