HIKVISION WD22PURU-78 2TB Surveillance Level HDD

The WD22PURU-78 2TB  is  a variant of the Hikvision WD22PURX-78, a 2TB hard disk drive (HDD) designed for surveillance systems. Here’s a detailed description of the WD20PURX-78:

Components:

• Platters: The drive uses magnetic platters to store data. These spin at a speed (RPM) optimized for surveillance workloads (likely 5400 RPM in this case).
• Read/Write Heads: These heads travel across the platters, reading and writing data as instructed.
• Cache: A small amount of high-speed memory (64MB in this case) that acts as a buffer, storing frequently accessed data for quicker retrieval.
• Controller Board: This circuit board controls the overall functionality of the drive, including data transfer and communication with the system.
• Motor: The motor spins the platters at a constant speed.

Application Areas:

• Security Surveillance Systems: WD20PURX-78 is specifically designed for surveillance systems. It’s optimized for workloads involving frequent writes, rewrites, and streaming data – typical in security systems that record video continuously.
• Network Attached Storage (NAS) Devices: This HDD can be used in NAS devices for storing surveillance footage or other data requiring constant recording or access.
• Digital Video Recorders (DVRs): It can be used as storage for DVRs that record video from security cameras.

Additional Features (likely for WD20PURX-78):

• IntelliPower: This technology optimizes power consumption and reduces noise levels during operation.
• Workload Rating: This indicates the amount of data the drive can handle per year (likely 180TB/year for WD20PURX-78).
• High Reliability: Surveillance applications demand reliable storage, and this drive is likely designed for extended operation with minimal errors.
