TOSHIBA S300 2TB Surveillance HDD

The Toshiba S300 2TB Surveillance Hard Drive (model HDWT720UZSVA) is a purpose-built 3.5-inch internal hard drive designed to handle the continuous, write-intensive demands of modern security and surveillance systems. Unlike general-purpose desktop drives, the S300 is rated for 24 hours a day, 7 days a week operation, making it a dependable choice for DVR, NVR, and video management system deployments. The S300 connects via a SATA 6.0 Gbit/s interface and spins at 5,400 RPM, delivering a sustained data transfer speed of up to 184 MB/s (typical) with a 128 MB buffer to smooth out the bursty write patterns that characterise multi-channel surveillance recording. Average rotational latency is 5.56 ms. The drive supports simultaneous recording from up to 32 high-resolution cameras and is compatible with systems housing up to 8 drive bays, enabling scalable storage expansion as your camera count grows. Reliability is a cornerstone of the S300's design. Toshiba rates the drive for a mean time to failure (MTTF) of 1,000,000 hours and a sustained annual workload of up to 180 TB/year. The unrecoverable read error rate is 1 in 10^14 bits, and the load/unload cycle rating stands at 600,000. An integrated shock sensor helps protect data integrity in environments subject to vibration or accidental knocks, while the rated operating vibration tolerance of 4.90 m/s² (0.50 G) at 5–350 Hz further underpins stability in multi-drive enclosures. The S300 uses Shingled Magnetic Recording (SMR) technology and supports Advanced Format (AF) 4K-sector alignment. It is both RoHS compatible and halogen-free, reflecting Toshiba's commitment to environmental compliance. Operating power consumption is a modest 4.01 W (typical), dropping to 2.08 W at active idle, which helps manage thermal output across long duty cycles. Idle acoustics are rated at 21 dB (typical), keeping noise levels low in office or semi-exposed installations.
