Current high-capacity IronWolf Pro database
Seagate IronWolf Pro Model List: 12TB to 32TB
Look up current Seagate IronWolf Pro model numbers from 12TB through 32TB, including the newest 28TB, 30TB and 32TB drives. Compare capacity, transfer specification, workload rating, MTBF, warranty and likely buying role.
Quick answer
The current high-capacity IronWolf Pro ladder includes ST12000NT001, ST14000NT001, ST16000NT001, ST18000NT001, ST20000NT001, ST22000NT001, ST24000NT002, ST28000NT000, ST30000NT011 and ST32000NT000. The 28TB, 30TB and 32TB models use Seagate’s newer high-capacity platform, with the 32TB ST32000NT000 listed up to 285MB/s. Verify the complete suffix because capacity alone does not identify a model.

Current IronWolf Pro offers across capacities
Verified exact-model identity remains eligible for at least 336 hours after successful confirmation. Amazon prices and images refresh separately on 24-hour clocks. If Amazon exposes buying options without one featured numeric price, the card shows Price Options. Generation, interface, capacity, security class and exact model are enforced.

Why an exact Pro model database is necessary
IronWolf Pro spans several platform generations, and marketplace pages often combine capacities or reuse specification blocks. A buyer can easily read the transfer rate, cache or power figure for a neighboring variation instead of the selected drive. The model number is the reliable key that connects a listing to the correct Seagate data sheet.
Cloudzat keeps model-level fields separate. A 16TB specification is not copied onto 20TB or 32TB merely because all three are called IronWolf Pro. When a current offer lacks a clear model, the price may still appear as a family offer, but the page does not invent missing technical values.
12TB through 24TB current models
The current high-capacity Pro ladder includes ST12000NT001 at 12TB, ST14000NT001 at 14TB, ST16000NT001 at 16TB, ST18000NT001 at 18TB, ST20000NT001 at 20TB, ST22000NT001 at 22TB and ST24000NT002 at 24TB. These drives are positioned at a 550TB-per-year workload tier and carry five-year limited warranties with three years of Rescue coverage where available.
Transfer ceilings vary. The 16TB air model is listed at 255MB/s, while several helium models are listed at 270MB/s or 285MB/s. This variation is one reason to avoid describing the entire family with one speed.
The 28TB, 30TB and 32TB generation
Seagate’s current high-capacity data sheet lists ST28000NT000 at 28TB, ST30000NT011 at 30TB and ST32000NT000 at 32TB. All are 7,200 RPM, CMR, helium sealed and equipped with 512MB cache. Listed maximum sustained transfer rates are 270MB/s, 275MB/s and 285MB/s respectively.
These capacities are aimed at dense NAS deployments where every bay is valuable. A four-bay system populated with 32TB drives reaches 128TB raw, but usable capacity, rebuild exposure and total cost still depend on RAID choice.
Workload, MTBF and warranty interpretation
Current IronWolf Pro models carry a 550TB-per-year workload rating. Most high-capacity models are listed at 2.5-million-hour MTBF, while the current 16TB profile lists two million hours. MTBF is a population-level reliability metric under specified conditions; it is not a forecast that one drive will operate for centuries.
The five-year limited warranty is easier to apply to ownership planning. Confirm serial eligibility, seller status and regional terms when the drive arrives. Three years of Rescue Data Recovery Services adds another recovery path but does not eliminate the need for independent backup.
How capacity changes array economics
A larger Pro drive can reduce spindle count, preserve bays and lower the number of components that consume power. It can also concentrate more data on each disk and raise replacement cost. The optimum depends on enclosure price, RAID overhead, expected growth and whether downtime can be tolerated during expansion.
Compare cost per usable terabyte rather than only price per drive. Four 24TB disks and three 32TB disks both provide 96TB raw, but their RAID choices, fault tolerance, throughput and future expansion are different. The cheapest raw capacity is not automatically the safest architecture.
Compatibility with current NAS systems
High-capacity support must be checked against the exact NAS. A system may physically accept SATA drives but have a tested-capacity ceiling, firmware requirement or compatibility warning. New 28TB to 32TB models may take time to appear on vendor lists even when the SATA interface is familiar.
Check the NAS model, operating-system version, drive model and firmware. Update the NAS before installation when the vendor recommends it. For production use, test the drive and confirm temperature, SMART visibility and alerting before migrating important data.
Performance, network and rebuild planning
A 270MB/s to 285MB/s drive can exceed one-gigabit networking by a wide margin. Multi-drive arrays on 10GbE or faster links can use more of the sequential capability, but random workload remains limited by mechanical latency. CPU, memory, encryption and protocol overhead can also constrain results.
Rebuild time grows with capacity and workload. Larger drives do not automatically mean proportionally longer real rebuilds because speed and used space matter, but the amount of data at risk is substantial. Maintain backup, avoid running drives hot and choose RAID protection appropriate to the number and size of disks.
Buying and documenting IronWolf Pro correctly
Record the model, serial number, firmware, seller, purchase date and warranty result for every drive. Keep the packaging until the initial test period passes. Do not buy a mixed lot under one broad product title without checking each variation, particularly when older and newer model suffixes are combined.
For a business array, consider purchasing a tested spare or documenting a compatible replacement. Availability can change over a five-year system life. A model database is valuable because it lets the replacement plan use exact technical identity rather than a vague “same capacity” rule.
How Cloudzat evaluates IronWolf drives
Cloudzat attaches capacity, family, interface, recording class, transfer rate and warranty only to an exact model. Standard IronWolf, IronWolf Pro, WD Red Plus and the SATA-only Exos comparison set remain separate so one family never inherits another family’s specifications.
Live offers are screened for new single internal 3.5-inch drives and matched to an exact model. Standard IronWolf never collapses into IronWolf Pro, WD Red Plus stays separate, and the Exos comparison set is SATA-only. SSDs, SAS listings, external drives, accessories, enclosures, multipacks and non-new listings are rejected.
