Western Digital 8TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 128 MB Cache, 3.5" - WD84PURZ

Product Information

aucun des disques WD RED (2, 4, 8 To) intégrés dans les NAS clients n'a eu UN seul pb depuis 5 ans (+ de 20 NAS RAID 1 mini) … Darin die beiden kleinen Kartons mit den Festplatten in ihren Formteilen/Antistatik-Tüte waren aber unbeschädigt.

Allerdings wundert mich, dass beide Festplatten exakt das gleiche Störungsbild aufweisen wenn das ein Transportschaden sein soll. Wäre mehr als merkwürdig. Três vezes a carga de trabalho nominal de nossos discos rígidos para desktop. As capacidades de 8 TB, 10 TB e 12 TB apresentam carga de trabalho nominal de 360 TB/ano.Die Einstellung im Adv.Powermanagement von Hard Disk Sentinel war auch auf 254 gestanden - also deaktiviert, wie es sich gehört. TB a 3 TB (WD30PURZ) suportam até oito compartimentos; 3 TB (WD33PURZ) e 4 TB e acima suportam até 16 compartimentos. Es gibt ja in der Größe 8TB leider nur Festplatten von WD oder Seagate. Und die Seagate drehen alle mit 7200Upm (toll gemacht Seagate, will ja jeder eine kleine Turbine im Rechner / Videogerät / NAS. Naja, nur nicht ärgern... Da bleibt nicht wirklich viel Auswahl.

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. With regard to speed, I really can't comment. Since it's part of a multi-drive redundant array, I can't measure the speed of any one drive. That being said, I'm sometimes doing multiple, simultaneous read/write HD video streams and I've never had so much as a stutter. So, it's certainly good enough for my application. 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.Gravadores modernos podem suportar vários streams de vídeo por câmera. As unidades WD Purple suportam até 64 câmeras HD de um stream 5. Com tantas opções, você tem a flexibilidade de fazer o upgrade ou expandir suas aplicações de segurança no futuro. The WD Purple™ Pro HDD, with OptiNAND™ technology in 22TB 1, delivers big capacity in an enterprise-class drive for video analytics servers, AI, and deep learning systems to enable data-driven outcomes.

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. Single stream per camera @ 3.2Mbps (1080p, H.265, 25 fps). Results may vary depending on camera resolution, file format, frames per second, software, system settings, video quality, and other factors. WD Purple™ Pro drives are optimized to handle up to 64 single-stream HD cameras 2 in addition to 32 concurrent AI streams. This flexibility allows you to easily upgrade and scale your smart video solution to meet your changing needs.

Vielleicht ein thermischen Rekalibrieren der Köpfe (sowas hatte ich mal bei uralten, ewig gelaufenen Fileserver-Platten) Du coup, je vais refaire l'inventaire des disques achetés et être plus vigilant sur les dates de fabrication (origine) désormais. AllFrame AI technology supports up to 32 AI streams for deep learning analytics within the system while reducing frame drops.
