Product Features
Built for NAS Use in 1-24 Bays: Designed for NAS environments, this drive supports setups from 1 to 24 bays so you can scale from a simple home system to a larger multi-drive enclosure. That flexibility makes it easier to grow your storage without changing your drive class. With 4TB capacity, it fits well for shared files, backups, and always-on storage needs. Support for business and personal use helps it match both work and home workflows.
7200RPM Performance with SATA 6Gb/s: Running at 7200RPM, the drive is made to keep data moving smoothly when multiple users or tasks hit the NAS at once. SATA 6Gb/s connectivity helps maintain strong throughput in compatible systems. A stated data transfer rate of 750.0 megabits_per_second supports responsive access for common NAS activities. With 256MB cache, frequently accessed data can be handled more efficiently during everyday use.
CMR Recording for Consistent Operation: Using CMR recording, the drive is built for predictable behavior in NAS workloads where steady performance matters. This can be especially helpful when your system is handling ongoing file transfers, backups, or multi-user access. CMR also aligns well with environments where reliability and consistency are priorities. It is a practical choice for users who want stable storage behavior over time.
Reliability and Protection Technologies: Enhanced reliability is supported through 3D Active Balance Plus technology and error recovery controls with NASware 3.0 technology. Extended drive testing helps ensure each drive is tested for extended reliable operation, giving added confidence for always-on usage. Vibration and shock protection is included to help the drive handle the physical conditions common in multi-bay enclosures. Together, these features are aimed at keeping your NAS running smoothly day after day.
