28 TB CMR NAS drive

The Seagate IronWolf Pro ST28000NT000 is a 28 TB internal hard drive built for 24×7 operation in multi-bay commercial and enterprise NAS systems. It uses CMR recording technology at 7200 RPM with a 512 MB cache to deliver sustained performance under RAID workloads. Media professionals, SMBs and teams running on-prem AI model training gain massive capacity without compromising reliability.

Standard 3.5-inch SATA installation

The drive fits a standard 3.5-inch bay and connects through a SATA 6.0 Gb/s interface with no special cables or adapters required. AgileArray firmware handles dual-plane balancing and time-limited error recovery automatically, reducing the RAID rebuild issues that often appear with desktop drives in multi-bay enclosures. Physical dimensions are 146.99 mm long, 101.85 mm wide and 26.11 mm high.

Verify bay count and vendor list

Confirm that your NAS chassis has enough 3.5-inch bays and that its power supply can support the additional drive. Check the NAS vendor compatibility list for the ST28000NT000 before ordering, as approved firmware revisions vary by manufacturer. Systems limited to smaller capacities or desktop-class drives will not support this 28 TB enterprise model.

Questions about this item

How can I confirm the 7200 RPM drive is performing correctly after installation?

Use your NAS vendor's built-in SMART monitoring or Seagate's IronWolf Health Management tool to verify drive temperature, error counts, and RAID sync status during the first 24 hours of operation.

What comes in the box and what must I purchase separately?

The drive ships in retail or OEM packaging; you will need to supply your own SATA data cable, SATA power cable, and 3.5-inch drive bay mounting screws for installation.

Which capacity version should I choose for a multi-bay NAS RAID array?

This model provides 28TB of CMR storage; select it when you need maximum raw capacity per bay for 24×7 enterprise workloads such as video production or on-prem AI model training.
