The Seagate IronWolf Pro 30TB, model ST30000NT011, is the middle capacity in Seagate's newest high-capacity IronWolf Pro NAS generation. It is close enough to 28TB and 32TB that the right answer is rarely about capacity alone.
The useful question is whether 30TB gives your NAS a better balance of density, current availability and price per usable terabyte than the adjacent models. This page treats ST30000NT011 as a specific buying decision, not another broad 30TB hard-drive catalogue page.
The IronWolf Pro 30TB is the balanced pick when ST30000NT011 is meaningfully cheaper per TB than the 32TB model but gives enough extra density over 28TB or 24TB to reduce bay pressure. If the 32TB listing is close on $/TB, buy the 32TB instead; if 28TB is discounted, the 30TB middle slot can lose its purpose.

Workload rating is recorded per part number from Seagate's datasheet for that exact model, not blanketed across the line — two drives of the same capacity can differ because they are different generations. A dash means the figure is not stated for that listing. Recording technology comes from the manufacturer's published CMR/SMR list; a model absent from that list is shown as UNVERIFIED rather than guessed. Rows priced above 3× this line's in-stock median are flagged and excluded from the winner callout and from every median we compute.
This table is computed from live DatacenterDisk rows when an exact in-stock match exists. It is intentionally blank for unavailable models rather than filled with stale prices.

Raw capacity is not usable capacity. This table shows the slot-level math before filesystem overhead, snapshots, reserved space and vendor-specific parity layouts.
| Drive count | Raw capacity | Single-parity usable | Dual-parity usable |
|---|---|---|---|
| 4 bays | 120TB | 90TB | 60TB |
| 6 bays | 180TB | 150TB | 120TB |
| 8 bays | 240TB | 210TB | 180TB |
| 12 bays | 360TB | 330TB | 300TB |
Middle capacities are easy to misbuy. A 30TB drive looks like a simple upgrade from 28TB, but it only adds 2TB per bay. In a four-bay single-parity layout, that is 6TB usable before overhead. In a 12-bay dual-parity layout, it is 20TB usable. The larger the array, the more the middle slot matters.
ST30000NT011 keeps the NAS-focused IronWolf Pro traits: CMR, SATA, 7200 RPM, 512MB cache, RV sensors, IronWolf Health Management, 550TB/year workload rating and a five-year warranty. The purchase case is therefore not about a different workload class. It is about slot efficiency and price.
If you are replacing a mature 24TB array, 30TB produces a 25 percent raw capacity lift with the same drive count. That can delay a chassis migration, which is often worth more than a small drive-price premium. If you still have open bays, the math changes and lower capacities often win.
Against 28TB, the 30TB model is a finer decision. The extra capacity is useful for 8-bay and 12-bay arrays, but a launch premium can erase it quickly. Watch the live $/TB table and compute at the array level rather than per single drive.
Because ST30000NT011 is CMR, TrueNAS and ZFS users do not face the host-managed SMR restrictions that apply to WD HC680 and HC690. That does not make rebuilds short. A full resilver at 30TB capacity remains a long window of elevated risk, especially in same-age arrays.
Plan dual parity for large vdevs, avoid mixing several new and old capacities without knowing the layout consequences, and check the enclosure's maximum supported capacity. A NAS that recognizes older IronWolf Pro drives is not guaranteed to have firmware validation for this exact model.
The IronWolf Pro 30TB is a strong buy only when the market gives it a clear role between 28TB and 32TB. Its specs are credible and NAS-appropriate, but the deciding number is live usable cost at your bay count.
For procurement, treat ST30000NT011 as an exact model. Do not accept a generic 30TB Seagate listing unless the full model number is visible.
The current 30TB IronWolf Pro model covered here is ST30000NT011.
Yes. Seagate's current IronWolf Pro data sheet lists the 30TB ST30000NT011 as CMR.
Buy 30TB when it is materially cheaper per usable TB. If 32TB is close on live $/TB, the 32TB model gives more slot value.
No. Price per TB is the first screen, not the whole decision. Match recording method, interface, bay count, firmware support, warranty position and rebuild risk before accepting the cheapest row.
