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. As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.

WD WD64PURZ Purple 6TB SATA Hard Drive w/ 5400RPM 6Gb/s 256MB WD WD64PURZ Purple 6TB SATA Hard Drive w/ 5400RPM 6Gb/s 256MB

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.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. 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 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. 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. 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. million bytes, 1GB = 1 billion bytes, and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment. through 3TB (WD30PURZ) support up to eight bays; 3TB (WD33PURZ) and 4TB and above support up to 16 bays. H.264, also known as Advanced Video Coding (AVC), was introduced in 2003 and is an efficient video compression standard commonly used for HD video (720p and 1080p) and Blu-Ray discs.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. As used for storage capacity, 1TB = WD AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications 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.

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. 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.

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. The WD Purple WD64PURZ drive features a workload rating of up to 180TB/year — up to three times that of desktop drives — to handle the unique demands of mainstream video surveillance DVR and NVR systems.

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. 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. 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.
