Seagate IronWolf Pro 3.5" 12TB, 7200 RPM, 256MB, 550 WRL, SATA III Hard Drive for NAS

The Seagate IronWolf Pro ST12000NT001 is a 12 TB internal hard drive with a 3.5-inch form factor, engineered for multi-user NAS systems that require continuous operation. It is built to function 24/7 and supports a workload rate of up to 550 TB per year, making it a suitable component for demanding business environments. The drive integrates rotational vibration (RV) sensors to mitigate vibration in multi-bay enclosures, which helps maintain consistent performance. Its design focuses on long-term reliability for collaborative workflows and data archiving.

Performance is delivered through a 7200 RPM spindle speed, a SATA 6Gb/s interface, and a 256 MB cache. This combination facilitates sustained data transfer speeds of up to 270 MB/s for both read and write operations, enabling efficient handling of large files. The drive is compatible with IronWolf Health Management, a feature in select NAS systems that offers proactive system monitoring and data recovery options. This function provides an additional layer of data protection by analyzing drive parameters to suggest preventative actions.
