Toshiba S300 2TB 5400 RPM Surveillance Desktop Internal HDD

The Toshiba S300 (model HDWT720UZSVA) is a 3.5-inch internal hard drive engineered specifically for always-on surveillance environments. Spinning at 5400 RPM with a SATA 6.0 Gbit/s interface, it delivers a sustained maximum data transfer speed of 184 MB/s and a 128 MB buffer, making it well-suited to continuous high-definition video recording workloads across multiple camera channels simultaneously. Built for round-the-clock operation, the S300 is rated for 24×7 use and carries a workload rating of 180 TB per year. Its mean time to failure (MTTF) is rated at 1,000,000 hours, while the unrecoverable read error rate stands at 1 per 10^14 bits read, offering a high degree of data integrity for long-term surveillance footage retention. The drive supports up to 32 cameras and is compatible with enclosures housing up to 8 drive bays, making it a practical choice for small-to-medium CCTV and DVR/NVR installations. The S300 employs SMR (Shingled Magnetic Recording) technology and features an integrated shock sensor to help protect against accidental data loss. It is RoHS-compliant and halogen-free, and supports Advanced Format (AF) for compatibility with modern storage controllers. Power consumption is kept low at 4.01 W typical during operation and 2.08 W at active idle, helping to keep thermal output and electricity costs manageable in multi-drive NVR cabinets. Idle acoustics are rated at a quiet 21 dB typical. The drive is backed by a 3-year manufacturer warranty.
