Seagate ST4000NM0023-cr 4TB SAS Enterprise HDD Renewed

The Seagate Enterprise Capacity 3.5 HDD, part of the Constellation ES series, is designed for the demanding requirements of enterprise data centers, servers, and network-attached storage systems. With a 4TB capacity and 7200 RPM spindle speed, it delivers dependable sequential and sustained throughput for applications such as bulk data storage, backup repositories, and always-on file serving. The 128MB cache helps smooth data transfers and improve responsiveness during mixed workloads, while the SAS interface provides the reliability, error-handling, and multi-initiator support that enterprise environments demand.

This particular unit is certified refurbished, meaning it has undergone functionality testing, inspection, and cleaning to meet performance standards comparable to new drives. It ships with a minimum 90-day warranty, offering a cost-effective solution for expanding storage capacity in professional environments. However, potential buyers should be aware that the SAS interface is not interchangeable with SATA — a compatible SAS controller or host bus adapter is required. The 3.5-inch form factor fits standard server chassis and storage enclosures, making it a straightforward addition to existing enterprise infrastructure.
