[ IDENTIFIED SURVEILLANCE HDD // MODEL-SPECIFIC RECORD ]
Toshiba S300 AI HDWTA80EZSTA
8 TB; 3.5-inch; SATA 6.0 Gbit/s. S300 AI surveillance drive identified by its complete HDWTA80EZSTA model number. Specifications below are tied to the manufacturer’s capacity/model table; do not treat other capacities or suffixes as interchangeable.
IDENTIFICATION: The manufacturer datasheet lists this exact retail number and capacity. The maker’s product page and datasheet specify AI-surveillance recording and CMR. Verify the exact nameplate and revision before procurement, service or recovery.
Recorded specifications
| Exact manufacturer number | HDWTA80EZSTA |
|---|---|
| Capacity | 8 TB (decimal, manufacturer-rated) |
| Form factor | 3.5-inch; check chassis clearance, mounting, carrier and cooling. |
| Interface | SATA 6.0 Gbit/s (manufacturer-rated); backward link negotiation depends on the host controller. |
| Rotational speed | 7,200 rpm |
| Buffer / cache | 512 MB (manufacturer-listed buffer) |
| Recording technology | CMR (conventional magnetic recording) |
| Annual workload rating | 550 TB/year; this is a rated annualized workload, not a guarantee of performance or suitability for every RAID rebuild or write pattern. |
| Surveillance workload | 24/7 AI surveillance infrastructure; Toshiba specifies up to 64 cameras, 32 simultaneous AI streams and systems with up to 24 drive bays. The 550 TB/year rate and CMR design target continuous video plus analytics writes; verify the NVR/analytics server’s HBA and RAID qualification. |
| Host compatibility | The maker datasheet identifies SATA 6.0 Gbit/s, Advanced Format and up to 24 bays. Validate 8 TB LBA/GPT support, sector presentation, firmware qualification, power and airflow with the NVR/HBA vendor. A SATA connector alone does not establish compatibility with a given DVR, NVR, HBA, expander, RAID controller or enclosure. |
Host integration and recording notes
- Use a SATA-capable DVR/NVR, HBA or backplane that supports this capacity and the manufacturer’s documented workload; confirm drive-bay count, airflow, vibration and power requirements in the exact system’s qualification list.
- All cited Toshiba specifications identify a 3.5-inch SATA device. SAS-only hosts are not automatically compatible; verify SATA-device support for the actual controller, expander and enclosure.
- Use a GPT-aware operating system and confirm the NVR/RAID stack supports this capacity, address range and sector presentation before initializing. Preserve any system-specific provisioning or firmware procedures.
- Recording method matters: SMR can behave differently under sustained random writes, rebuilds and repeated overwrites than CMR. Use the manufacturer’s stated surveillance application and do not substitute desktop benchmarks for a workload qualification.
- If the drive contains wanted data and reports errors, avoid writes, formatting, repeated power cycles and stress tests. Capture model, firmware, host and symptom details and consult a qualified recovery specialist.
