Seagate IronWolf 3.5" 4TB, 5400 RPM, 256MB, SATA 6 Gb/s Hard Drive for NAS

This 3.5-inch internal hard disk drive is specifically engineered for Network Attached Storage (NAS) environments, offering 4 TB of storage capacity. The drive utilizes a SATA III interface, supporting transfer speeds up to 6 Gbit/s. Operating at 5400 RPM and integrated with a 256 MB buffer, the hardware provides sustained data throughput necessary for file sharing, backup, and media streaming applications in home and small office setups.

The architecture supports continuous 24/7 operation, meeting the reliability requirements of always-on storage solutions. Critical reliability specifications include an MTBF of 1,000,000 hours and a yearly workload rating limit of 180 TB. Rotational Vibration (RV) sensors stabilize the drive within multi-bay enclosures, ensuring consistent performance. The drive delivers a maximum sustained data rate of 202 MB/s during sequential read and write operations.
