Why this product
Built for 24/7 NAS operation
Rated for 180TB of data throughput per year and 8760 continuous hours annually, this drive is engineered to run without pause in networked storage environments.
RAID-optimized with AgileArray
Dual-plane balancing and Time-Limited Error Recovery make this drive work efficiently in multi-bay arrays, minimizing rebuild times and improving overall system stability.
3 years of data recovery included
Comes with three years of complimentary Rescue Data Recovery Services with an industry-leading 95% recovery rate, eliminating out-of-pocket recovery costs.
Vibration tolerance for multi-bay systems
Built-in RV sensors detect and compensate for vibration in crowded enclosures, maintaining consistent performance even when other drives are operating nearby.

- Form factor3.5"
- InterfaceSATA III 6 Gb/s
- Sequential readUp to 202 MB/s
- Rotational speed5400 RPM
- Warranty3-year limited
- SKUSEA-1708
- EAN7636490078309
- Works in any 1-8 bay NAS system using SATA III 6 Gb/s connections.
- Supports RAID configurations with optimized error recovery for multi-bay arrays.
- Not designed for standalone desktop or laptop use; it is a NAS-specific drive.
- Cannot be used in systems requiring more than 8 bays.
Best for
- Small offices and SOHO environments needing reliable shared storage that runs 24/7 without supervision.
- Home users building a multi-bay NAS to back up family photos, videos and documents with built-in redundancy.
- RAID arrays where vibration from multiple spinning drives can impact performance; RV sensors keep this drive stable in crowded bays.
Trade-offs
- Desktop computers or external USB enclosures; this is a NAS drive and lacks optimization for single-drive use.
- Users requiring faster sequential performance; at 202 MB/s sustained transfer, it is slower than enterprise-class or high-speed alternatives.
- Systems running longer than 3 years without replacement; the warranty covers only three years.
- Installations with more than 8 bays; it is not rated or optimized for larger arrays.
