Toshiba S300 4TB3.5-InchSurveillance

Toshiba S300 Surveillance Hard Drive — a 4TB 3.5-inch SATA III HDD purpose-built for 24/7 surveillance recording with a 180TB/year workload rating and rotational vibration compensation.

The S300 (HDKPB08Z0A02S) is optimised for the continuous-write workloads typical of CCTV and NVR systems. Most desktop drives carry far lower annual workload ratings and can fail prematurely under surveillance duty cycles. RV (Rotational Vibration) sensors maintain stable operation in multi-drive enclosures where vibration from neighbouring drives can degrade performance. The 128MB cache and ~157MB/s sustained transfer rate support smooth simultaneous recording from multiple camera streams. Backed by a 3-year warranty.
