Capacity, connection & physical fit
Check the drive format and usable capacity before ordering.
| Capacity | 8TB decimal[1] |
|---|---|
| Form factor / interface | 3.5-inch / SATA 6Gb/s[1] |
| Recording / enclosure fill | CMR / Air[1] |
| Height × width × depth | 26.11 × 101.85 × 146.99 mm[1] |
| Typical mass | 720g[1] |
| Sector format | 512-byte logical / 4096-byte physical[3] Manual Rev. F; 512e. |
| Heads / discs | 10 heads / 5 discs[3] |
Transfer speed & response
Rated transfer speed describes a particular operation, not every file copy.
| Spindle / cache | 7200 rpm / 256MB[1] |
|---|---|
| Rated outer-track sustained transfer | 210 MB/s[1] |
| Power-on / standby to ready | 23s typical; 30s maximum[3] Manual Rev. F, start/stop table. |
| Transfer definition | 200 MiB/s (210 MB/s)[3] Manual Rev. F; not SATA interface bandwidth or a full-disk benchmark. |
| Average latency | 4.16 ms[3] |
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] Population/design rating; not a measured lifespan for an individual drive. |
| Unrecoverable read error rating | 1 per 10^15 bits read[1] |
| Limited warranty / Rescue service | 3 years / 3 years; Rescue availability varies by country[1] |
| Annualized failure rate statement | 0.87% based on 8760 POH (manual)[3] Population statistic under stated conditions, not a life guarantee. |
Power & startup requirements
Allow for both continuous operation and the power needed to spin up.
| Startup current (typical, 12V) | 1.8A[1] |
|---|---|
| Average operating | 10.1W[1] |
| Average idle | 7.8W[1] |
| Typical standby / sleep | 1.0W[1] |
| Voltage tolerance including noise | 5V ±5%; 12V ±10%[1] |
| Manual Table 2 average idle at 25°C | 7.16 W (0.233 A @ 5 V + 0.503 A @ 12 V)[3] Not merged with the 7.8 W datasheet idle or 10.1 W average operating rows. |
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) | 70G / 300G[1] |
| Humidity / altitude | 5–95% non-condensing; operating −304.8 to 3048m[3] Manual Rev. F; maximum humidity gradient 20% per hour. |
| Manual operating shock: read / write | 70 G read / 40 G write, 2 ms[3] Rev. F §2.7.1 distinguishes read and write; datasheet combined 70 G label above is less specific. |
| Operating vibration | 5–22 Hz: 0.25 G; 22–350 Hz: 0.50 G; 350–500 Hz: 0.25 G[3] Rev. F Table 1; lower band displacement-limited, at drive mounting points. |
| Rotational / non-operating vibration | 20–1500 Hz: 12.5 rad/s² operating; 10–500 Hz: 5.0 Grms non-operating[3] Rev. F Table 1. Distinct vibration modes, not directly interchangeable. |
| Temperature gradient / wet-bulb limit | 20°C/hour operating and non-operating; 29°C maximum wet bulb[3] Rev. F Table 1 and §2.6.2; non-condensing. |
| Non-operating altitude | −304.8 to 12,192 m[3] Rev. F §2.6.3; separate from operating maximum 3048 m. |
| Manual maximum mass | 716 g[3] Rev. F Table 1 says maximum 716 g; DS1904.23 lists typical 720 g. Source-version inconsistency retained; neither value is a measured sample weight. |
Sound ratings & measurement conditions
Manufacturer sound ratings do not tell you how loud your assembled NAS will be.
| Typical idle / seek (datasheet dBA) | 28 / 32[1] Manufacturer rating, not an installed NAS sound-pressure measurement; idle uses Idle 1 state. |
|---|---|
| Typical / maximum sound power | Idle 2.8 / 3.0 bel; seek 3.2 / 3.4 bel[3] Rev. F Table 1 and §2.8: A-weighted ISO 7779 sound power, free field over reflecting plane. Do not read this as a sound-pressure level at a listener. |
Exact product identity & open questions
- Manufacturer part number
- ST8000VN004[1]
- Long-term reliability: No controlled exact-MPN field failure-rate study is adopted. Warranty and MTBF/AFR 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. IHM/HCL still need a host-specific check. Newegg uses an NE- listing prefix.
- Power definitions: Rev. F manual Table 2 has 7.16 W average idle at 25°C versus 7.8 W average idle in DS1904.23. These are not merged into a tested wattage.
- Current US offer coverage: Newegg selected primary new offer was $329.99 on September 11. Other merchant observations retain their original dates. QNAP stock and pre-order wording still conflict.
- Video: Wong video ASR/frames integrated without dBA. A1lF6okQ-No has no ASR; 5:10 frame is unreadable; owner 277 MB/s and 4-platter claim are not adopted over the official 10 heads / 5 discs.
