One 32TB ST32000NT000 · 3.5-inch SATA · CMR / HAMR
This guide combines Seagate DS2129.7 and Seagate’s CMR/SMR classification with original ST32000NT000 tests from ComputerBase and StorageReview. 32TB IronWolf Pro is Mozaic HAMR CMR: HAMR is the write method, CMR is the track layout, not SMR. Long writes still needed extra airflow in ComputerBase’s lab. ChooseCompute has not tested this drive. See the review evidence ↓
32TB raw capacity in one bay, if the exact model is supported.[1]
Full-drive writing benefited from direct airflow.[3]
Small random I/O is a different strength from sequential transfers.[4]
Manufacturer drive ratings do not describe your finished enclosure.[1]
Follow any specification for its full conditions and sources.
Living with it
A 32TB drive puts more data in each bay. It makes sense when replacing the enclosure would be difficult, but check the exact model against the NAS compatibility list before ordering. RAID and formatting leave less usable space than the capacity printed on the label.[1][2]
ComputerBase’s full-drive write improved from 201.1 MB/s to 218.5 MB/s with a fan in front of the drive, and the collapse below 100 MB/s after ~22 TB went away. A milder lasting write slowdown still appeared and was not explained by temperature, so extra airflow is necessary planning, not a promise that write speed stays flat. Startup stayed under 25 W; average CDM power was 7.6 W.[3]
The direct tests support large-file storage. Small random requests remain a different workload, so do not expect the responsiveness of an SSD for virtual machines or busy databases.[4]

A manufacturer-loaned ST32000NT000 averaged 201.1 MB/s on a full-surface write and 218.5 MB/s with a fan in front of the drive. The severe drop after ~22 TB went away with that fan, but a milder lasting write dip remained and is not a temperature story. CrystalDiskMark 8 SEQ1M was 294.1/286.7 MB/s at Q8T1 and 292.5/290.9 MB/s at Q1T1. Access times were 11.9 ms read and 7.3 ms write. Average CDM power was 7.6 W; startup stayed below 25 W.

Tested: ST32000NT000; full-drive write test, repeated with a fan directly in front of the drive. Firmware and full host configuration not stated.
Applies to: Exact 32TB model; long writes rather than NAS-network throughput.

FIO sequential 284/283 MB/s used a 10 GB footprint, not a full-surface pass. BlackMagic was 253.4/228.3 MB/s and PCMark 10 Data Drive 609. Optional extras: LLM 10-run mean load times 48.7773 / 73.2398 / 73.8927 s and 3DMark Storage 175. Capacity and NAS features are the buying point, not winning these desktop synthetics.

Before you buy
On 2026-09-11 DiscTech listed ST32000NT000 new at $1,379 in stock. The same day’s Newegg pane showed TechnoDealsUSA at $1,699 in stock as the visible primary, and a separate Newegg-sold alternative at $1,159.99 out of stock. Older Amazon/B&H/Adorama rows keep their 2026-09-08 times.[10][12][11]
Choose the array layout first, then compare the required number of drives. A 32TB label is raw decimal capacity, not the final usable capacity of a protected array.[1]

No. This exact model uses HAMR to assist writing and is specified as CMR. It should not be confused with an SMR model.[1][2]
SATA and physical fit are only part of the check. Confirm the exact drive model, 32TB capacity and firmware support with your NAS vendor. The unlimited-bay rating is not universal compatibility approval.[1][2]
That is the manufacturer’s maximum at the outer diameter. Network speed, disk position, workload, cooling and the array change actual transfer rates.[1][3][4]
We have no controlled enclosure-noise result for this exact drive. The manufacturer gives idle and seek ratings, but the case, mounts, fans and number of drives change what you hear.[1]
The five-year limited warranty and three-year Rescue service do not replace an independent backup. Service availability and warranty eligibility depend on the purchased drive and region.[1]
No. CrystalDiskMark 8 reached about 294/287 MB/s on short sequential tests. Full-surface writes averaged 201.1 MB/s, or 218.5 MB/s with a fan, and a milder lasting dip remained even when cooled.[3]
