Available in standard S300 (up to 6TB, 110-180TB/year workload) and S300 Pro (6-10TB, 7200 RPM, 300TB/year). Best value: The S300 4TB at ~$89 ($22.25/TB) for budget home systems.

Toshiba S300 4TB (HDWT140UZSVA)
4TB Capacity | 5400 RPM | 128MB Cache | CMR | 180TB/year Workload | Up to 64 Cameras | 3-Year Warranty
Budget-friendly surveillance drive with 24/7 operation support and CMR recording. Proper surveillance firmware at a lower price point than WD Purple or SkyHawk. Ideal for home systems with up to 8 cameras.
Not everyone needs the premium features of WD Purple or Seagate SkyHawk. The Toshiba S300 fills an important niche: reliable surveillance storage at a lower price point. For home security systems with 4-8 cameras where budget matters more than enterprise features, the S300 delivers the essentials.
Toshiba may not have the marketing presence of WD or Seagate in surveillance, but they’ve been making reliable hard drives for decades. The S300 series offers proper surveillance optimization — 24/7 operation, CMR technology, and multi-camera support — without the premium pricing.
