Product description
Dahua DHI-SSD-S820S512G is a state-of-the-art SATA solid-state drive specially developed for mobile surveillance applications (e.g. car DVRs). High-performance controller and 3D NAND ensure data transmission stability even at high video stream flow. Support for TRIM and NCQ technologies improves write performance, and low power consumption makes the drive ideal for power-constrained environments.
Key features
- 3D NAND technology: increased durability and data writing speed.
- High vibration and shock resistance: 1500G/0.5ms (half sine wave).
- TRIM, S.M.A.R.T. and Garbage Collection support: automatic performance optimization and longer life.
- Long life: up to 1,500,000 hours MTBF (Mean Time Between Failures).
- Low power consumption: up to 2.2 watts in operation mode, 0.48 watts at rest.
