Key strengths
CMR recording, a rotational-vibration sensor and error recovery control are specified for 1–8 bay NAS use, with IronWolf Health Management on supported NAS systems.
Rated for 24×7 operation (8,760 power-on hours a year) with a 180 TB/year workload limit and 1 million hours MTBF.
Three years of Rescue Data Recovery Services are included alongside the three-year limited warranty, where the service is offered.
Before you buy
Seagate rates only an outer-diameter sequential maximum (210 MB/s) for this 7,200 RPM hard drive; its product manual adds a 4.16 ms average latency but gives no seek-time or random-access performance figures.
Seagate's data sheet rates it at 10.1 W average operating and 7.8 W idle power and 28–32 dBA acoustics, versus 5.3 W / 4.0 W and 25–26 dBA for the 5400 RPM ST8000VN002; the ST8000VN004 product manual lists a lower 7.16 W average idle.
The warranty is three years and the workload rating 180 TB/year, versus the five-year limited warranty and 550 TB/year workload rating Seagate states for its IronWolf Pro drives.

Source - Weight
- Conflicting sources
Seagate's data sheet (DS1904.23, ST8000VN004 column) and the product page's key specifications list a typical weight of 720 g (1.59 lb), while Seagate's ST8000VN004 product manual (Rev. F) lists a maximum weight of 716 g (1.579 lb). A typical weight above the stated maximum cannot both be right, so no single weight is recorded.

- Up to 210 MB/s maximum sustained transfer rate (outer diameter); 7200 RPM; 256 MB cache
Seagate maximum sustained transfer rate at the outer diameter (OD); Seagate states actual data rates may vary depending on operating environment and other factors. Seagate's IronWolf product page copy says 'delivering sustained data rates up to 180 MB/s' without naming a model or capacity; the data sheet's ST8000VN004 column gives 210 MB/s, which is the figure recorded here. Seagate data sheet DS1904.23 first table; ST8000VN004 is the fourth model column (16TB ST16000VN001, 12TB ST12000VN0008, 10TB ST10000VN000, 8TB ST8000VN004, 8TB ST8000VN002). Not our measurement.

- Warranty terms and endurance if applicable
- 3-year limited warranty; rated workload 180 TB/year; 3 years of Rescue Data Recovery Services included
Seagate states Rescue services are not available in all countries. Workload rate limit is a rating, not a warranty write cap stated by Seagate.
- Workload rate limit
- 180 TB/year
Seagate workload rate limit (WRL); drives are specified for 8,760 power-on hours per year (24×7).
Source - MTBF
- 1,000,000 hours
Seagate-rated mean time between failures (data sheet row 'Mean Time Between Failures (MTBF, hours)'). The product manual states an annualized failure rate of 0.87% (MTBF of 1,000,000 hours) over a 5-year service life in Enterprise Storage field conditions limited to 8760 power-on hours per year, a drive-reported HDA temperature of 40 °C or less, an ambient wet bulb of 26 °C or less and a typical workload, and calls the AFR (MTBF) a population statistic not relevant to individual units.

Power

- Power
- Data sheet: average operating 10.1 W, idle average 7.8 W; product manual: average idle 7.16 W, typical operating 9.16–10.02 W depending on workload; standby 1.0 W (both); startup current 1.8 A typical (12 V)
The two Seagate sources disagree on idle power: the data sheet (DS1904.23, ST8000VN004 column) lists 7.8 W idle average, while the ST8000VN004 product manual's Table 2 (DC power requirements, 8TB) lists 7.16 W average idle; neither figure is chosen. The data sheet gives one 10.1 W average operating figure; the manual gives only per-workload typical operating totals: 9.96 W random read 4K16Q, 9.16 W random write 4K16Q, 10.02 W sequential read 64K16Q and 9.54 W sequential write 64K16Q. Both list 1.0 W standby. The manual's typical figures are averages of drives tested under nominal conditions at 5.0 V and 12.0 V input and 25 °C ambient.
- Allowable supply voltage

- 0 °C ambient minimum to 65 °C drive-reported maximum
Seagate does not recommend sustained drive temperatures above 60 °C.

- 70 G (read) / 40 G (write); 2 ms
Seagate's ST8000VN004 product manual rates operational shock separately: 70 Gs for reads and 40 Gs for writes at a maximum pulse duration of 2 ms. The data sheet (DS1904.23, ST8000VN004 column, row 'Shock, Operating/Nonoperating: 2ms (max)': 70Gs/300Gs) gives a single 70 Gs operating figure, which matches the read rating.
