This article covers 東芝 2TB S300 監視 3.5インチ SATA 内蔵ハードドライブ 24時間365日稼働 64台のカメラをサポート 128MBキャッシュ.
Overview
Toshiba's S300 series is a 3.5-inch internal hard drive purpose-built for surveillance systems. The 2TB model (HDWT720UZSVA) is designed for 24/7 continuous operation, supporting up to 64 cameras. With a SATA 6Gbps interface and 5400rpm spindle speed, it delivers up to 160MB/s read and 150MB/s write speeds. The 128MB cache and Toshiba's Dynamic Cache technology help maintain smooth video streams. This drive carries a 180TB/year workload rating, making it suitable for constant recording environments. It uses SMR (Shingled Magnetic Recording) to achieve higher data density, which is fine for sequential write patterns typical of surveillance footage. The S300 sits in the entry-to-mid-range surveillance HDD segment, competing directly with WD Purple and Seagate SkyHawk series.
Compatibility Guide
The Toshiba S300 is a standard 3.5-inch SATA drive, compatible with any desktop PC or surveillance DVR/NVR that has a free SATA port and 3.5-inch bay. Power is supplied via a standard SATA power connector. Because this drive uses SMR technology, it is not recommended for RAID arrays or workloads involving frequent random writes. It works best with surveillance recorders that perform sequential writes; check your recorder's compatibility list before purchase.
Product Info
The Toshiba S300 2TB (HDWT720UZSVA) is positioned as a budget-friendly surveillance HDD. It has been on the market for several years and is widely available through online retailers. Key specs include 5400rpm rotation, 128MB cache, and advanced format (4K sector) support. The sustained transfer rate is 160MB/s read and 150MB/s write. Workload rate is rated at 180TB per year. Warranty is typically 2-3 years depending on the vendor. It is designed for 24/7 operation with low acoustic noise.
Best Use Cases
- Home Security Systems: With 2TB capacity, you can store several days of footage from 4-8 cameras at moderate resolution. The 24/7 reliability ensures your recordings are never interrupted. 2. Small Business Surveillance: For offices or retail stores running a few cameras, this drive offers a cost-effective solution without compromising uptime. 3. DVR/NVR Archival: If you need a secondary storage drive for bulk footage storage, the S300's sequential write performance is adequate. However, avoid using it as a primary OS or scratch drive due to SMR's poor random write performance. ## Alternatives
Direct competitors include the Western Digital Purple 2TB (WD22PURZ) and Seagate SkyHawk 2TB (ST2000VX017). The WD Purple uses CMR technology and includes AllFrame technology to reduce frame loss, while the SkyHawk supports up to 64 cameras with ImagePerfect firmware. The Toshiba S300 often undercuts them on price, but its SMR nature means lower random write performance. If you plan to run RAID or need consistent write speeds across many small files, consider a CMR surveillance drive instead.
Things to Consider
This drive uses SMR, which can cause performance degradation during heavy random write workloads. For pure surveillance recording, this is rarely an issue, but if you frequently delete and re-record over the same sectors, you may see speed drops. The 5400rpm speed is slower than 7200rpm alternatives, but for video streaming, the difference is minimal. Also note that the drive's maximum throughput (160MB/s) is far below modern SSDs, so it should not be used as a boot drive. Ensure adequate case airflow around the drive to prevent overheating, especially in 24/7 operation.
