Seagate IronWolf 4TB — ST4000VN006 NAS Hard Drive
4TB 3.5" SATA 6Gb/sUp to 8 Drive Bays180 TB/Year, 24x7CMR with RV Sensors
The Seagate ST4000VN006 is a 4 TB 3.5-inch IronWolf NAS hard drive for small and mid-sized network storage that runs continuously — rated for a 180 TB annual workload across 8760 power-on hours, in enclosures of up to eight drive bays. Seagate lists it under part number ST4000VN006; the EAN on this listing is 7636490078309, which matches the EAN Seagate prints in its own EU price list exactly. It is a conventional-recording (CMR) drive at 5400 RPM with a 256 MB cache, rotational vibration sensors and AgileArray firmware, and it ships with three years of Rescue Data Recovery Services. This is the 5400 RPM, 256 MB member of the 4 TB IronWolf range — not to be confused with the ST4000VN008, which is a different drive at the same capacity. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
This is IronWolf, not IronWolf Pro, and the gap between them is the thing to understand before buying. IronWolf is rated at 180 TB per year with a 1,000,000-hour MTBF, a 0.87% annualised failure rate and a ceiling of eight drive bays. IronWolf Pro is rated at 550 TB per year, 2,000,000 to 2,500,000 hours depending on capacity, and unlimited bays. The warranty differs too: three years here against five on Pro. Listings that quote 300 TB per year, 1.2 million hours or "up to 24 bays" against an IronWolf part are carrying across figures from the Pro range or from its older NE generation. ST4000VN006 and ST4000VN008 are two different 4 TB IronWolf drives, one digit apart. This VN006 runs at 5400 RPM with a 256 MB cache and rotational vibration sensors. The VN008 runs at 5900 RPM with a 64 MB cache. Listings substitute them freely. A second point worth knowing: the unrecoverable read error rate on the non-Pro IronWolf line is one sector per 10E14 bits, an order of magnitude worse than the 10E15 of IronWolf Pro and Exos — that difference matters more than capacity when you are sizing a RAID rebuild. There is also a Frustration-Free Packaging version of this exact drive, the ST4000VNZ06; the Z is packaging only and the drive inside is identical. Two points of accuracy: Rescue Data Recovery is included on current IronWolf drives for three years — older reseller copy claiming non-Pro has no Rescue is out of date — but Seagate’s footnote adds it is not available in all countries. And Seagate does not state whether this drive is helium-filled or air-filled, so we do not claim either.
Best For
✓ Two- to eight-bay NAS enclosures running continuously
✓ Home and small-office file, media and backup servers
✓ RAID sets where rebuild reliability matters — 1 error per 10E15 bits
✓ Multi-drive chassis with vibration — RV sensors are fitted
✓ Media libraries that outgrew a desktop drive
✓ Anyone wanting a NAS-rated drive with data recovery included
Key Features
Rated for continuous NAS duty
IronWolf is built for 8760 power-on hours a year at a 180 TB annual workload — a genuine 24x7 rating, unlike desktop drives rated for roughly 2400 hours. AgileArray firmware adds dual-plane balancing, RAID-optimised error recovery and time-limited error recovery, so the drive does not drop out of an array while retrying a sector. IronWolf Health Management reports on prevention, intervention and recovery on supported NAS platforms.
Eight bays, with rotational vibration sensors
Seagate rates IronWolf for enclosures of one to eight bays, and this capacity has rotational vibration sensors fitted — not universal in the family, since the 1 TB and 2 TB models lack them. That combination is what makes a four- or six-bay chassis practical without the spindles interfering with each other. Beyond eight bays, IronWolf Pro is the rated product.
Three years of Rescue Data Recovery, now included on non-Pro IronWolf
Rescue Data Recovery Services are bundled for three years on this drive. This is worth stating plainly because the older claim that Rescue is an IronWolf Pro exclusive is out of date — Seagate’s current IronWolf datasheet lists three years of Rescue for every capacity in the non-Pro line. If a drive fails, Seagate’s recovery lab attempts the recovery at no charge, once, within the term.
Three years of Rescue Data Recovery included
If the drive fails, Seagate’s Rescue service applies its recovery technology and returns what it can retrieve. Current IronWolf drives include three years of it — a change from the older generation, where Rescue was a Pro-only feature, and one that a good deal of reseller copy has not caught up with. Seagate’s footnote states the service is not available in all countries, so confirm availability rather than assuming coverage.

Frequently Asked Questions
Singular Expert Insight
IronWolf is the honest choice for a small NAS, and the wrong one for a growing array. What you are buying over a desktop drive is a genuine 24x7 rating, AgileArray firmware that will not drop a drive out of a RAID set mid-recovery, and rotational vibration sensors — all of which matter from the second drive onwards. What you are not buying is headroom: 180 TB a year and an eight-bay ceiling are real specifications, and a busy eight-bay box doing constant writes will sit closer to them than most people expect. The trade-off against IronWolf Pro is concrete: 180 TB a year rather than 550, one to eight bays rather than unlimited, a 1,000,000-hour MTBF rather than 2 million, a three-year warranty rather than five, and a 10E14 error rate rather than 10E15. What you keep is CMR, rotational vibration sensors, AgileArray, IronWolf Health Management and three years of Rescue. Compare the range in our NAS hard drives, and if the destination is a rack rather than a NAS chassis, the enterprise and server hard drives range is where the 550 TB workload ratings live.
Buyer’s Guide
Buy it if
You are filling a two- to eight-bay NAS that runs continuously and you want a drive actually rated for it: 180 TB per year, 8760 power-on hours, CMR, rotational vibration sensors, AgileArray firmware and three years of Rescue Data Recovery included. This one is current in Seagate’s EU price list, which is not true of every drive in the range.
Skip it if
Your enclosure holds more than eight drives, or the array does heavy sustained writing — both are outside what Seagate rates IronWolf for, and IronWolf Pro is the correct tier at 550 TB per year with unlimited bays. Skip it too if the drive is going into a desktop that is off overnight, where a BarraCuda costs less, or into a surveillance recorder, where SkyHawk is the right family.
Also consider
ST4000VN008 is the other 4 TB IronWolf — 5900 RPM, 64 MB cache, no RV sensors. ST4000VNZ06 is this same drive in frustration-free packaging. ST4000NT001 is the IronWolf Pro at this capacity: 7200 RPM, 550 TB a year, a 10E15 error rate and a five-year warranty. For a single-drive desktop rather than a NAS, BarraCuda costs less but is not rated for continuous operation.
