Seagate IronWolf Pro 3.5" 18TB, 7200 RPM, 256MB, SATA III Hard Drive for NAS

The Seagate IronWolf Pro ST18000NE000 is an 18 TB internal hard drive engineered for network-attached storage (NAS) systems. Its 3.5-inch form factor is standard for multi-bay enclosures in demanding multi-user environments. A rotational speed of 7200 RPM, combined with a 256 MB cache, facilitates efficient data retrieval and transfer for continuous operations. This design is intended to handle the high-volume data access and persistent workloads common in creative professional and small business settings.

This drive is rated for a workload of 300 TB per year and is built for 24/7 operation, ensuring consistent data availability. It incorporates Rotational Vibration (RV) sensors to mitigate vibration in multi-drive systems, which helps maintain stable performance and data integrity. The drive supports S.M.A.R.T. technology for monitoring drive health and predicting potential issues. Hot-swap compatibility also allows for drive replacement without system downtime in supported NAS configurations.
