Capacity and interface

The Seagate IronWolf Pro is a 20TB 3.5-inch internal hard drive that uses the SATA 6.0Gb/s interface. It spins at 7200 RPM and provides a 256MB cache with CMR recording technology. The drive is built for always-on operation in multi-bay NAS enclosures.

Who it suits and who it does not

This drive suits users who need 20TB of storage in a single bay and whose NAS supports SATA drives with AgileArray firmware. It is not for systems that only accept 2.5-inch drives or for workloads that exceed the 300TB per year rating. Buyers needing more than 24 bays per enclosure should also look elsewhere.

Deciding specification

The SATA 6.0Gb/s interface is the single specification that decides compatibility. The drive fits a standard 3.5-inch bay with maximum dimensions of 146.99mm length, 101.85mm width and 26.11mm height. Verify that the NAS controller and backplane support SATA before purchase.

Spørgsmål om denne vare

What does the SATA 6.0Gb/s interface limit in practice?

The SATA 6.0Gb/s link sets the maximum data rate for the drive, capping sequential transfer speeds at the interface ceiling.

What physical clearance does the 3.5" 26.11mm high drive require?

The drive measures 146.99mm long, 101.85mm wide and 26.11mm high, so the bay must accommodate those maximum dimensions.

How is the drive installed in a NAS and what step is often missed?

Mount the drive in a 3.5" bay using four screws, connect SATA data and power cables, then enable the IronWolf Health Management feature in the NAS OS for monitoring.
