ST3000VN000 Seagate NAS HDD 3TB: What Replaces It
The ST3000VN000 is a Seagate NAS HDD 3TB from the generation before the IronWolf name, and it is still searched for because the small NAS units it shipped in are still running. This covers what it is and what replaces it.
What is the Seagate ST3000VN000?
A 3.5 inch, 3TB, SATA 6Gb/s NAS-class drive from Seagate’s original NAS HDD line, the predecessor to IronWolf. 5900 RPM class, conventional magnetic recording, rated for small NAS enclosures.
It has not been manufactured for years. Supply is refurbished and used. Our availability guide covers why that matters.
Why is it still searched for?
Because two-bay and four-bay NAS units from that era are still in service, and when a drive fails, owners search for the exact part.
The good news: you do not need the exact part. A NAS array tolerates a replacement of the same class at equal or larger capacity, and modern IronWolf drives are the direct successor. The bad news: a used ST3000VN000 is old stock with unknown hours. Our hours guide covers judging it.
What replaces the ST3000VN000?
A current IronWolf at 3TB or larger. Two things to confirm.
It is CMR. Some NAS-class drives at small capacities shipped as SMR without clear labelling. Check the exact replacement part number. Our SMR vs CMR guide covers why.
Your NAS supports the replacement capacity if going larger. Older NAS units have limits.
Our IronWolf 8TB guide covers a current successor.
Is the ST3000VN000 CMR?
Yes. This part is conventional recording and was suitable for NAS RAID in its era.
Should I replace one drive or the whole array?
Honestly, if one drive from a set installed together has failed, the others are the same age. Drives installed together age together. Replacing one and waiting for the next failure is a plan for repeated rebuilds on ageing drives.
For a small NAS holding data that matters, migrating to a new set of current drives is frequently the better answer than sourcing old stock one at a time. Our drive lifespan guide covers the decision, and our backup guide covers why a backup must exist before any of this.
Frequently asked questions
Is the ST3000VN000 still available?
As used and refurbished stock only. It has not been manufactured for years. A current IronWolf is the direct successor and usually the better buy.
What replaces the ST3000VN000?
A current IronWolf at 3TB or larger, confirmed CMR, at a capacity your NAS supports.
Is the ST3000VN000 CMR?
Yes.
Can I mix a new IronWolf with old ST3000VN000 drives?
Technically yes at equal or larger capacity. But the old drives are the same age as the one that failed, so expect further failures. Migrating the whole set is frequently the better answer.
Can I put a larger drive in place of the 3TB?
If the NAS supports the capacity. Older units have limits. Check the compatibility list for your model.
Should I buy a used ST3000VN000?
Only with hours and health data checked, and only if a current IronWolf is not an option. Old stock with unknown hours is rarely the better buy.
