IronWolf — the non-Pro NAS line |
| Product Name |
Seagate IronWolf 4TB NAS Hard Drive |
| Part Number |
ST4000VN006 |
| MPN |
ST4000VN006 |
| EAN / GTIN |
7636490078309 — this is the value Seagate prints in its EU price lists. It does not derive from the UPC in the usual way, so some GTIN validators object to it; it is nonetheless the number Seagate publishes |
| UPC |
763649090985 |
| Drive |
| Capacity |
4TB |
| Form Factor |
3.5-inch |
| Interface |
SATA 6Gb/s — 600 MB/s maximum interface rate |
| Recording Technology |
CMR (conventional magnetic recording) — stated by Seagate; this is not an SMR drive |
| Drive Design |
Not stated by Seagate for this model — neither helium nor air is published |
| Rotational Speed |
5400 RPM. This figure comes from the datasheet only — the IronWolf product manual contains no spindle-speed row at all. Listings advertising this part at 7200 RPM are wrong; the 4 TB IronWolf that runs faster is the ST4000VN008, at 5900 RPM |
| Cache |
256 MB |
| Sustained Transfer Rate |
202 MB/s maximum in the datasheet; the product manual writes it as “193 (202MB/s)”, the lower figure being the sustained rate and the higher the peak |
| Sector Size |
512e — 512-byte logical, 4096-byte physical |
| Heads / Discs |
4 heads / 2 discs |
| Weight |
490 g |
| Height |
20.20 mm — not the 26.11 mm of the 6 and 8 TB IronWolf drives; check your caddy or tray if it is a tight fit |
| NAS Capability |
| Max Drive Bays |
Up to 8 — IronWolf Pro is the product rated for more |
| Rotational Vibration Sensors |
Yes — note these are not fitted across the whole IronWolf family; the 1 TB and 2 TB models lack them |
| Firmware |
AgileArray — dual-plane balancing, RAID-optimised and time-limited error recovery |
| IronWolf Health Management |
Yes, on supported NAS platforms |
| Reliability |
| Workload Rate Limit |
180 TB per year |
| MTBF |
1,000,000 hours |
| Annualised Failure Rate |
0.87% |
| Unrecoverable Read Errors |
1 sector per 10E14 bits read — an order of magnitude worse than the 10E15 of IronWolf Pro and Exos. This is the specification that most separates the non-Pro line |
| Power-On Hours |
8760 per year — rated for 24x7 operation |
| Power, Acoustics and Environment |
| Idle Power |
the datasheet says 3.96 W and the product manual says 3.2 W |
| Operating Power |
the datasheet says 4.8 W average and the product manual says 3.7 W — a 20 to 25% disagreement that runs through every power row on this drive |
| Standby |
0.5 W in the datasheet, 0.25 W in the product manual |
| Acoustics |
23 dBA idle, on which every document agrees. Seek is less settled: the current datasheet says 27 dBA, the newest product manual revision says 2.5 bels typical (25 dBA) and an older manual revision says 2.7 bels (27 dBA). Unusually, the newer manual is the quieter figure and the datasheet that post-dates it still says 27 |
| Operating Temperature |
0 degrees Celsius ambient to 65 degrees drive-reported |
| Services and Support |
| Rescue Data Recovery |
3 years included. This is current for IronWolf — older documentation and reseller copy state that only IronWolf Pro carried Rescue. Seagate’s footnote adds that the service is not available in all countries |
| Warranty |
1-Year Warranty (Singular) |
| Manufacturer Term |
Seagate publishes a 3-year limited warranty for IronWolf, identical in its AMER and EMEA datasheets — note this is three years, not the five that applies to IronWolf Pro. Singular’s direct warranty is 1 year; beyond that we assist you with the manufacturer’s warranty process for its full duration. |
