Toshiba S300 4TB Surveillance HDD – Always-On Storage for Security Systems
The Toshiba S300 4TB Surveillance Internal HDD (HDWT840UZSVA) is purpose-built for security and surveillance environments that require 24/7 reliability and consistent performance. With its 4TB storage capacity, this 3.5″ SATA drive offers robust support for up to 64 HD camera streams, making it ideal for both home and commercial surveillance systems.
Thanks to its 5400 RPM rotational speed and 157MB/s typical data transfer rate, you can count on smooth video recording and playback, even when multiple cameras are recording simultaneously.
Optimized for DVR and NVR Environments
Unlike regular desktop drives, the S300 is engineered to handle the demanding workloads of surveillance systems. Its SATA 6.0 Gbit/s interface and 128MB cache allow faster buffering and writing of large, continuous video files.
Furthermore, it supports continuous 24/7 operation, which is essential for always-on monitoring. Whether you’re capturing motion-triggered footage or streaming in real-time, the Toshiba S300 handles it with stability and speed.
Built to Last – Even in Multi-Camera Setups
Durability matters in video surveillance, especially in high-temperature or vibration-prone environments. That’s why the HDWT840UZSVA includes rotational vibration sensors and thermal protection technology to enhance long-term reliability.
It also supports a workload rating of up to 180TB/year, making it far more resilient than consumer-grade hard drives. This means you can install it and forget about it—knowing your data is safe and accessible at all times.
Moreover, Toshiba’s use of halogen-free components adds environmental sustainability without sacrificing performance.
Versatile Applications for Secure Environments
The Toshiba S300 4TB is ideal for:
-
Home or office security systems
-
Retail surveillance and monitoring
-
Small business DVR or NVR storage
-
AI-powered video analytics
-
Indoor and outdoor multi-camera setups
Its flexibility means it can be used in everything from small two-camera home installations to full-scale 64-channel systems.
