Transfer speed & response
NAS use, workload & warranty
Match your enclosure and workload; reliability ratings are not a lifespan guarantee.
| Rated bay range | 1–8[1] |
|---|---|
| Vibration and error control | RV sensor; dual-plane balance; error recovery control[1] |
| Annual workload / powered operation | 180TB/year / 8760 hours/year[1] |
| MTBF / load-unload rating | 1 million hours / 600,000 cycles[1][7] Population/design rating; not a measured lifespan for an individual drive. Manual rating assumes 8760 power-on hours/year, drive-reported HDA temperature ≤40°C, ambient wet-bulb ≤26°C, typical workload and stated contamination limits; maximum65°C operating limit is not the MTBF rating condition. |
| Unrecoverable read error rating | 1 per 10^14 bits read[1] |
| Limited warranty / Rescue service | 3 years / 3 years; Rescue availability varies by country[1] |
Power & startup requirements
Allow for both continuous operation and the power needed to spin up.
| Startup current (typical, 12V) | 1.8A[1] |
|---|---|
| Average operating | 3.7W[1] |
| Average idle | 3.2W[1] |
| Typical standby / sleep | 0.25W[1] |
| Voltage tolerance including noise | 5V ±5%; 12V ±10%[1] |
| Manual operating-power method | 40% random seeks, 40% read/write, 20% idle[7] Rev. U §2.5.1; nominal 5V/12V, 25°C; describes the manual method, not TechRadar measurements. |
Cooling & handling limits
Keep the drive within its temperature and environmental limits.
| Operating temperature | 0°C minimum ambient; 65°C maximum drive-reported[1] Seagate advises against sustained drive temperatures above 60°C. |
|---|---|
| Storage temperature | −40 to 70°C ambient[1] |
| Shock, operating / nonoperating (2ms) | 80G / 300G[1] |
| Humidity | 5–90% operating; 5–95% nonoperating[7] Rev. U Table 2; maximum gradient 30% per hour. |
| Altitude | Operating −304 to 3048m; nonoperating −304 to 12,192m[7] Rev. U Table 2. |
Sound ratings & measurement conditions
Manufacturer sound ratings do not tell you how loud your assembled NAS will be.
| Typical idle / seek (datasheet dBA) | 23 / 25[1] Manufacturer rating, not an installed NAS sound-pressure measurement; idle uses Idle 1 state. |
|---|---|
| Typical / maximum sound power | Idle 2.3 / 2.4 bel; seek 2.5 / 2.6 bel[7] Rev. U Table 2 and §2.7: A-weighted ISO 7779 sound power; cover upward over reflecting plane. Not a sound-pressure level at your seat. |
Exact product identity & open questions
- Manufacturer part number
- ST4000VN006[1]
- Long-term reliability: No controlled exact-MPN field failure-rate study is adopted. Warranty and MTBF do not establish the lifespan of the unit you receive.
- Physical revision and NAS compatibility: Merchant pages do not guarantee a complete dash suffix or firmware. No blanket compatibility claim is made.
- Acoustics and Adorama stock: No controlled sound-pressure test; Adorama exact new PDP retained without a current price because availability was not exposed.
- Review metadata: The selected TechRadar comparison does not provide the IronWolf firmware or complete PC configuration; conclusions remain limited to the reported test.
- Current US offer coverage: On 2026-09-11 Newegg’s visible primary price for ST4000VN006 was $189.99 in stock (Newegg-sold). Do not use the $369.99 related-item figure that appears earlier in the saved HTML. Older B&H and Amazon rows keep their original dates. Confirm seller, new condition and shipping at purchase.
- Memory4Less listing: https://www.memory4less.com/seagate-hard-drive-st4000vn006 was not confirmed as an exact new US PDP (Cloudflare block). No price, seller, or condition was recorded.
