NAS internal hard drive designed for reliable, high-capacity storage in network-attached and RAID environments. Peace of mind for home and small business users who need consistent performance and data safety. Can Seagate IronWolf Pro NAS Hard Drive handle the demands of a busy NAS and RAID array?
⚡ At a Glance
- • Storage Performance: Sustained throughput from a 7,200 RPM spindle and 256 MB cache, with SATA 6 Gb/s interface
- • Best for: Home and small business NAS users running RAID and network-attached storage arrays
- • Not ideal for: Environments that require 2.5-inch drives or ultra-portable external storage
4 TB, 3.5-inch NAS drive with 7,200 RPM and 256 MB cache. CMR recording, SATA 6 Gb/s interface, and three years Rescue Services included.
Faster file transfers, with 7,200 RPM rotational speed
Higher rotational speed reduces average latency and raises sustained transfer rates compared with slower-spinning drives. The combination of physical throughput and SATA 6 Gb/s helps maintain steady sequential performance.
Improved responsiveness for large file copies, backups and media streaming, and quicker RAID rebuilds when drives are replaced.
Generous capacity for multi-drive arrays, with 4 TB storage
Each 4 TB drive increases total array capacity without adding more drives, simplifying array management and reducing the number of spindles needed for a given storage target.
Hands-free expansion of media libraries and backup pools, meaning fewer drives required to reach multi-terabyte storage goals.
Smoother mixed workloads, with 256 MB cache and CMR recording
Large cache buffers read and write bursts, while CMR (Conventional Magnetic Recording) preserves consistent sequential write behaviour that suits RAID configurations.
Reduced risk of performance drops under sustained or mixed transfers, keeping NAS services responsive during heavy use.
