IronWolf Pro 28TB: specifications and dated store comparison →28 TB per bay when enclosure space is running out
One 28 TB ST28000NT000 drive · 3.5-inch SATA · CMR · 7200 RPM
This guide combines Seagate DS2129.7 and Seagate’s CMR/SMR list for ST28000NT000 with dated US listings and two sets of owner reports. StephaneL (Materiel.net) copied a few files at 200–250 Mo/s on a USB dock under Windows 11. Best Buy’s eight 28TB reviews include damaged arrivals and a six-disk RAID 6 that was fine so far; those reviews carry incentivized and verified-purchaser badges and are not a failure rate. No professional laboratory of this exact 28TB MPN was found. 32TB ComputerBase numbers stay related. ChooseCompute has not tested this drive. See the review evidence ↓
CMR recording and the annual workload class suit always-on NAS storage.[1]
28 TB per bay provides substantial raw capacity; usable space depends on redundancy.[1]
Enclosure vibration and seek noise need separate consideration; no room-noise guarantee follows from the specification.[1][2]
A 7200 RPM mechanical drive has rotational delay; capacity-focused NAS storage is its main role.[2]
Follow any specification for its full conditions and sources.
Living with it
A pair of 28 TB drives in a simple mirror provides roughly 28 TB before formatting and filesystem overhead. Four equal drives with one drive of parity provide roughly 84 TB before overhead. These are capacity calculations, not measurements; snapshots and reserved space reduce what remains.[1]
The 550 TB/year workload class, RV sensors and RAID-oriented error recovery suit frequent shared storage use. They do not make a single drive redundant or make an unsupported NAS configuration approved.[1]
The 270 MB/s outer-track rating describes the drive under manufacturer conditions. Network speed, parity, small files and the NAS processor can all limit transfers. Buy the capacity and workload class you need; do not equate SATA link speed with file-copy speed.[1]
This model is useful when a nearly full enclosure needs more space per bay. Confirm that the enclosure, controller and firmware recognize this exact capacity before buying several drives. A higher-capacity disk still needs enough backup capacity and time for full-drive recovery.[1][2]
Seagate lists 28TB IronWolf Pro as Mozaic HAMR CMR, the same recording class as 32TB. DS2129.7 still gives ST28000NT000 270 MB/s OD versus 285 MB/s for ST32000NT000, with shared 512 MB, 6.8/8.3 W and 28/32 dBA rows. ComputerBase’s uncooled 32TB sequential-write drop is a cooling caution for dense 10-platter drives, not a measured 28TB curve.[1][5][6][8]
StephaneL’s 200–250 Mo/s figure is a few-file copy on a USB dock. Best Buy reviewers describe damaged cartons, mixed working units and a RAID 6 that had been fine so far. Those pages carry incentivized and verified-purchaser badges. Check the drive you receive for damage and know the return window. Do not copy ComputerBase’s 32TB full-surface write collapse onto ST28000NT000.[9][10][5]

Tested: Purchase 2026-04-14. Header ST28000NT000; review variant 28 To / 512 Mo. Windows 11, NTFS-GPT. File copy via INOVU Dual Dock QS Station USB dock bought years earlier.
Applies to: Exact 28TB IronWolf Pro owner report. 200–250 Mo/s is a few-file copy on a USB dock, not a laboratory average or RAID result.

Limits to keep in mind
Eight reviews on the 28TB page, all incentivized and verified. Useful cautions: inspect for shipping damage, RMA/return windows, and mixed working/damaged units. GaryR’s six-disk RAID 6 was fine so far. None of this is a measured failure rate.

Limits to keep in mind
Before you buy
On 2026-09-11 Newegg’s visible primary price for ST28000NT000 was $1,019.99 in stock (Newegg-sold). Older B&H and Adorama rows keep their 2026-09-08 times.[7]
Multiply the dated per-drive price by the number of drives you need, then allow for backup storage, a replacement plan and any network upgrade. Compare usable capacity after redundancy rather than adding raw TB alone.[1]
The datasheet lists 6.8 W average idle and 8.3 W average operating power per drive. Actual energy depends on workload, sleep settings and background tasks; include the NAS enclosure itself separately.[1][2]
Check ST28000NT000, 28 TB, one-drive quantity, new condition and the actual seller before paying. A standard retail listing can also display separate used offers or a different default marketplace seller.[1]

Yes. Seagate lists ST28000NT000 as CMR in its model-specific datasheet column.[1]
No. The drive is designed for NAS use, but controller support, maximum capacity and vendor firmware qualification still matter. Check the exact enclosure and drive model together.[1][2]
No. It is an annualized transfer workload that includes reads and writes. It is not an SSD-style lifetime TBW figure.[1][2]
No. Warranty and recovery services have conditions and do not guarantee recovery. Keep an independent copy of important data.[1][2]
No. StephaneL reported copying a few files at 200–250 Mo/s on a USB dock under Windows 11, without a screenshot or elapsed time.[9]
No. Several incentivized, verified-purchaser reviews describe damage or DOA units and return-window trouble. That is a reason to inspect packaging, not a failure-rate statistic.[10]
