Toshiba S300 Pro 10TB Surveillance Hard Drive 3.5" SATA 7200RPM

The Toshiba S300 Pro 10TB (SKU: HDD-10TB-TOSHIBA-3.5-SATAIII) is a surveillance-grade internal hard drive built for DVR and NVR recorders that run around the clock.

Why this matters for a CCTV install

A standard desktop hard drive isn't built for the write-heavy, always-on job a recorder does. The S300 Pro series is engineered specifically for 24/7 video recording, so it's a safer choice for a system that never gets switched off.

Key specs

• Capacity: 10TB — enough headroom for long-term footage retention across several cameras
• Interface: 3.5-inch SATA III (6 Gb/s), fitting most modern DVR and NVR bays
• Spindle speed: 7200 RPM for consistent throughput with high-resolution streams
• Cache: 256 MB buffer to help smooth data transfer during continuous capture
• Workload: rated for multi-camera surveillance recording, not just single-stream use

Before you buy

Check your recorder's maximum supported drive capacity and confirm it has a free 3.5-inch SATA bay — most DVR/NVR units do, but older or budget models sometimes cap out below 10TB. If you're recording from many high-definition cameras simultaneously, a 7200 RPM drive with this cache size is a sensible match for sustained sequential writes rather than short bursts.

This drive suits DVR systems, NVR recorders, professional security installations and dedicated video storage servers where reliable long-term recording capacity is the priority.
