ST8000VN004 Seagate IronWolf 8TB: IronWolf vs Pro vs Exos
The ST8000VN004 is a Seagate IronWolf 8TB, the standard NAS-class drive at a capacity where it competes with enterprise drives on price. This covers what it is, IronWolf versus IronWolf Pro versus Exos at 8TB, and what to check.
What is the Seagate ST8000VN004?
A 3.5 inch, 8TB, SATA 6Gb/s drive from the IronWolf family. 7200 RPM class, conventional magnetic recording, rated for NAS operation in enclosures up to a stated bay count, with NAS-oriented firmware and health monitoring.
VN identifies standard IronWolf. Our part numbers guide covers Seagate suffixes.
Is the ST8000VN004 CMR?
Yes. This specific part is conventional recording. Worth stating clearly because some NAS-class drives at nearby capacities from various manufacturers shipped as SMR without clear labelling, and the ST8000VN004 is not one of them. Our SMR vs CMR guide covers why to check every part number.
IronWolf vs IronWolf Pro vs Exos at 8TB
Three classes, three price points.
IronWolf (VN) — for small to mid-size NAS units, moderate workload rating, standard warranty. The ST8000VN004.
IronWolf Pro (NT) — higher workload rating, more bays supported, longer warranty. For busy or many-bay NAS units.
Exos (NM) — enterprise nearline, highest workload rating, SAS option, for rack servers and arrays.
For a home or small office NAS with a few bays and moderate use, standard IronWolf is the right class and the cheapest. For a busy NAS or many bays, Pro. For a server, Exos. Our drive class guide covers the differences in detail.
Where the ST8000VN004 fits
Small and mid-size NAS units on the vendor compatibility list.
Home and small office backup targets.
Matching an existing IronWolf array.
Where it does not: rack servers behind enterprise RAID controllers, where the workload rating is below what the platform expects and a vendor controller may flag it. Our OEM guide covers what happens with non-coded drives.
What to check before buying
NAS compatibility list for your model. Bay count against the IronWolf rating for your enclosure size. Whether the workload justifies Pro instead. And backup, because RAID is not backup. Our backup guide covers the principle.
Frequently asked questions
Is the ST8000VN004 CMR or SMR?
CMR. Suitable for NAS and RAID.
IronWolf or IronWolf Pro for my NAS?
IronWolf for small to mid-size NAS units with moderate use. Pro for busy units or many bays, where the higher workload rating and longer warranty are worth the premium.
Can I use the ST8000VN004 in a server?
Behind an HBA in a small server, yes. Behind an enterprise RAID controller, the workload rating is below what the platform expects and the controller may flag it. Exos is the right class there.
Is it on the Synology compatibility list?
Check the list for your exact model. IronWolf drives are widely listed, but the list is per model and per firmware.
What does VN mean in the part number?
Standard IronWolf. NT is IronWolf Pro; NM is Exos.
Is the IronWolf 8TB helium filled?
Check the datasheet for the exact revision. 8TB sits at the boundary where both air and helium designs exist.
