Western Digital WD120EDAZ 12TB 3.5" SATA Internal HDD 5400RPM

The Western Digital WD120EDAZ is a 12TB 3.5-inch internal hard disk drive designed for high-capacity storage applications in desktop systems, external enclosures, and entry-level surveillance environments. Featuring a SATA III 6Gb/s interface, the drive provides reliable data transfer performance suitable for large-volume storage and backup requirements. Operating at a 5400 RPM class speed, this model prioritises reduced power consumption, lower acoustic output, and thermal efficiency, making it suitable for continuous operation in enclosed systems such as NVRs, DVRs, and NAS devices with moderate workloads. The use of Advanced Format (AF) 4K sector technology ensures improved storage efficiency and compatibility with modern operating systems and recording platforms. The WD120EDAZ is commonly deployed in systems requiring high storage density rather than high-performance write endurance. It is suitable for small to medium CCTV installations where recording demands are not intensive, as well as general-purpose data storage, archiving, and backup. This drive integrates with standard SATA-based infrastructure and supports typical RAID configurations for redundancy. It is important to note that this model is not a dedicated surveillance-grade drive and is best suited for environments with controlled workload requirements.
