7. Other features:
- Technology: AllFrame technology from Western Digital to optimize data streaming and reduce image errors in surveillance systems
- Energy consumption: Energy efficient for continuous operation
Features
- SATA III interface: The use of the SATA III interface enables a data transfer rate of up to 6 Gb/s. This ensures fast data transfers, which are required for storing and managing large amounts of data.
- 5,400 RPM speed: The relatively low speed results in lower heat and noise levels, which is beneficial for 24/7 operation in surveillance systems. However, the lower speed can limit performance somewhat compared to hard drives with 7,200 RPM or more.
- 64 MB cache: The cache acts as a fast buffer for frequently used data, which improves performance by reducing the number of direct disk accesses.
- AllFrame technology: This technology optimizes the data stream for surveillance systems by improving the transfer of data and minimizing the image errors that can arise from frequent write and read operations.
- Continuous operation reliability: The WD Purple series is specifically designed for continuous use in surveillance systems, allowing the hard drive to operate reliably under high loads.
Application area
The Western Digital WD40PURX-78AKYY0 hard drive is especially suitable for the following applications:
1. Surveillance systems:
- Video surveillance: This hard drive is ideal for use in surveillance systems as it is optimized for continuous operation and features AllFrame technology, which improves video recording performance and reduces image errors.
2. Continuous operation:
- 24/7 use: The hard drive is optimized for 24/7 operation in continuous access environments. This makes it particularly suitable for use in systems that constantly record data, such as surveillance or archiving systems.
3. Backup and storage systems:
- Data storage: The high capacity of 4 TB is suitable for storing large amounts of data, be it for backups, archiving or large data archives.
4. Expansion of existing systems:
- Additional storage: Can be used as additional storage space for existing systems to expand available storage space and improve system performance.
5. Cost-effective data storage:
- Value for money: The WD Purple hard drive offers a cost-effective solution for storing large amounts of data, especially in applications where the highest performance is not absolutely necessary, but reliability and continuous operation are important.
Summary
The Western Digital WD40PURX-78AKYY0 is a robust 4 TB hard drive from the WD Purple series designed for use in surveillance systems and other applications with continuous operation. With a SATA III interface, 5,400 rpm speed and 64 MB cache, it offers solid performance for storing large amounts of data, while at the same time being energy efficient and reliable in continuous operation. AllFrame technology optimizes the data stream for surveillance tasks and reduces image errors, making it particularly suitable for continuous video recording. The high capacity and reliability of the hard drive make it an excellent choice for surveillance and archiving solutions.
