Workload & reliability ratings
Population and workload ratings do not predict one unit's life.
| Annual workload rating | 180TB/year read, written or verified[1] Toshiba annualizes as (lifetime writes + lifetime reads) × 8760 / power-on hours when power-on ≥ 8760 h; if power-on is shorter, the rate is writes + reads. Stated under 40°C ambient. After the rating the drive may decline; this does not change the warranty. Workload is data written, read or verified by host commands. |
|---|---|
| MTTF | 1,200,000 hours[1] Population statistic, not a lifespan. Footnote 7 pairs this column’s 1,200,000 hours with AFR 0.73% under 24×7, this model’s workload rating, and average HDA surface ≤40°C. Case/HDA surface above 40°C may degrade reliability and reduce the warranty period. That is not the 5–60°C operating-surface range. |
| Unrecoverable error rate | 1 per 10^15 bits read[1] |
| Load/unload cycles | 600,000[1] |
Warranty & support
Confirm regional coverage and proof-of-purchase requirements.
| Limited warranty | 3 years[1] Standard limited warranty. Footnote 7: HDA surface above 40°C may reduce the warranty period. |
|---|
Power & spin-up planning
Size power and cooling for active work as well as idle.
| Operating power | 6.94W[1] Toshiba method: 80% random read/write and 20% performance idle. |
|---|---|
| Active Idle-A power | 3.66W[1] Do not treat Active Idle-A as identical to another vendor's idle state. |
| Supply voltage | 5 VDC +10%/-7%; 12 VDC ±10%[1] |
| Startup current | Unknown; not stated in the adopted exact-model table[1] |
| Standby / sleep power | Unknown; not stated in the adopted exact-model table[1] |
Temperature, vibration & shock
Stay within the documented installation and handling limits.
| Operating temperature | 5 to 60°C drive surface[1] Drive-surface operating range. MTTF and warranty conditions use average HDA surface ≤40°C, not this 60°C maximum. |
|---|---|
| Non-operating temperature | −40 to 70°C[1] |
| Operating vibration | 7.35 m/s², 5–300 Hz; 2.45 m/s², 300–500 Hz[1] |
| Non-operating vibration | 29.4 m/s² (3.0G), 5–500 Hz[1] |
| Operating / non-operating shock (2ms) | 490 / 1,960 m/s²[1] |

Exact product identity & open questions
- Manufacturer part number
- HDWG81GXZSTA[1]
- Product
- One 16TB internal 3.5-inch SATA HDD from the Toshiba N300 family; enclosure and additional drives sold separately.[1]
- Revision rule
- Match the complete HDWG81GXZSTA suffix on the listing and delivered label; another 16TB family member is not interchangeable evidence.[1]
- Bulk / OEM packaging MPN
- HDWG81GUZSVA[1]
- Long-term reliability: No controlled exact-MPN field failure-rate or service-life study is adopted. Workload, MTTF and warranty ratings do not predict the life of the delivered unit.
- Host compatibility: Bay-class statements (up to 12 bays) still require the NAS vendor compatibility list, firmware and capacity ceiling for the installed enclosure.
- Current US offer coverage: No exact-MPN new main offer returned a usable selected page on 2026-09-11; B&H/Amazon/Adorama/Newegg/Micro Center/Walmart/Connection attempts were blocked or incomplete. 1 older listing(s) remain historical only.
- Original exact-MPN testing and indexing: Exact-MPN searches still found no applicable original test with enough configuration and visible results to adopt. Related-family tests are retained separately. Keep the page noindex pending suitable testing and independent editorial review.
- Unpublished exact-model specifications: The adopted official column does not state startup current, standby/sleep power or seek acoustics. Those fields remain Unknown rather than being copied from another MPN.
- Video contact: YouTube candidates from prior audits and this round were not given complete ASR plus identity frames in this session. No listening or dBA inference is claimed.
