Seagate IronWolf Pro 16TB 3.5" 7200RPM SATA III Internal NAS HDD

The Seagate ST16000NT001 is a 16TB 3.5-inch hard drive built for network attached storage systems that need to stay online around the clock. It connects through a SATA III 6 Gb/s interface and uses conventional magnetic recording, delivering sustained transfer rates up to 270 MB/s. A 7200 rpm motor and a 256 MB cache keep active files moving quickly, so multiple users in a multi-bay NAS or RAID array can open and save large projects without wait.

IronWolf Pro drives are engineered for heavy workloads, and this model is no exception. A workload rating of 550 TB per year and a projected mean time between failures of 2.5 million hours make it a strong fit for small offices, creative studios, and home labs that rely on uninterrupted access to data. Every copy, stream, or backup can run day and night with confidence.

Seagate backs the drive with IronWolf Health Management, a monitoring layer that works with compatible NAS operating systems to track drive conditions and suggest preventive actions before issues appear. If the unexpected happens, the included three-year Rescue Data Recovery Service offers a safety net, helping you recover critical files and keep downtime to a minimum.
