Ich denke mal du bist auch auf den Mydealz Link
gestoßen. Hier wird für unter 200EUR eine 8TB HDD angeboten. Unter anderem mit 1 per 10E15 Nonrecoverable Read Errors und 24x7 etc. "Nachteil": HDD soll nur für sog. DVR-Anwendungen/Systeme geeignet sein.
Deine Frage würden mich auch interessieren...weiss hier jemand genaueres? In den Kommentaren unter dem Deal wird davon geredet dass DVR-Platten keine/geringere Error-Correction/Detection haben um ein flüssiges Streamen/Bild zu erhalten....Andere meinen wieder dies ist nur der Fall wenn eine (DVR)-Anwendung den sog. ATA-Streaming-Command nutzt (spezielle Sata Commands).
Von den Features her sieht die Platte eigentlich TOP aus:
• 1M hour MTBF - designed for high write duty cycle across Surveillance HDD
• ATA AV Command support - streaming video command support across Surveillance HDD
• Best-in-class acoustic performance means virtually silent operation
• Built-in error recovery for non-stop video streaming
• Compliant with RoHS requirements in China and Europe
• Full-track multiple-sector transfer capability without local processor intervention
• Idle3 power mode support
• Low activity power
• Native Command Queuing with command ordering to increase performance in demanding applications
• Performance-tuned for seamless video applications
• Reliability for 24×7 video surveillance applications
• Rotational Vibration - mitigation of system level rotational vibration inside Surveillance HDD
• SeaTools® diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• State-of-the-art cache and on-the-fly error-correction algorithms
• Streaming video optimization - consistent command completion times & ERC support across Surveillance HDD
• Support for S.M.A.R.T. drive monitoring and reporting
• Supports "8+" drive bays
• Supports ATA8 streaming commands
• Supports latching SATA cables and connectors
• Supports up to 64 cameras
• TGMR recording technology provides the drives with increased areal density.
• Thermal monitoring and reporting for 24×7 operations
• Transient power on management - <=1.8A spin-up current
• Uncompromising reliability supports flexible surveillance design with case temperatures up to 70oC
• Workload ratings of 180TB/year
• Worldwide Name (WWN) capability uniquely identifies the drive
