ST1000VX000, ST2000VX000, ST3000VX000 specifications

Seagate's ST3000VX000, ST2000VX000, and ST1000VX000 are part of the company's SkyHawk surveillance hard drive lineup, which is engineered specifically for video surveillance systems. These drives are designed to handle the intensive workloads associated with continuous video recording in security environments, making them ideal for both commercial and residential surveillance applications.

The primary feature of these drives is their optimized performance for 24/7 operation. Each model is geared towards handling a significant amount of data, which is crucial for high-resolution video recording. The ST3000VX000 offers a substantial 3TB capacity, while the ST2000VX000 and ST1000VX000 provide 2TB and 1TB, respectively. This range of storage options allows users to select a drive that fits their specific storage needs, regardless of the scale of their surveillance system.

Another notable technology in these drives is their AllFrame technology, which supports streaming video playback by minimizing frame loss and improving overall playback reliability. This is particularly important for security applications where video integrity is paramount. AllFrame technology enhances the drive's ability to handle multiple streams of high-definition video, ensuring smooth recording and playback without interruption.

These drives are also built with Seagate's ImagePerfect firmware, which is designed to ensure clear and uninterrupted streaming on multi-camera setups. This firmware optimizes the drives for the unique demands of surveillance environments, allowing for resilience against the challenges posed by continuous workloads.

Additionally, the ST3000VX000, ST2000VX000, and ST1000VX000 are equipped with advanced vibration tolerance features. These technologies minimize the effects of vibrations from nearby drives, extending the lifespan and reliability of the drives in multi-bay NAS and surveillance environments. The drives also feature a workload rating of up to 180TB per year, signifying their capacity to endure substantial data write workloads typically associated with recording video.

Moreover, these drives come with a range of safety features, including thermal monitoring and reliability enhancements, which contribute to their durability in diverse operating conditions. With a mean time between failures (MTBF) rating of 1 million hours, they are designed to be dependable under continuous usage.

In summary, Seagate's ST3000VX000, ST2000VX000, and ST1000VX000 models represent a robust choice for surveillance needs, combining high storage capacities, advanced technologies, and reliability features tailored for video recording. These characteristics make them an excellent option for users seeking performance and durability in their security systems.
