Frequently asked questions

What interface speed does the Toshiba HDEPF02DAA51 support?

The drive features a SAS 12.0 Gbps interface, providing high-speed connectivity suitable for modern enterprise servers. This speed supports parallel multi-drive configurations and enables efficient data transfer in RAID arrays without creating performance bottlenecks in datacenter environments.

What is the storage capacity and form factor?

The HDEPF02DAA51 provides 4TB of storage in a standard 3.5-inch LFF form factor. This size is compatible with enterprise server bays and reduces the total number of drives required for typical datacenter deployments, lowering power and cooling requirements.

How does the 128MB cache improve performance?

The 128MB cache reduces latency by buffering frequently accessed data, improving throughput during sequential operations and reducing seek overhead. Combined with the 7200 RPM spindle speed and 8.5ms average seek time, the cache enables consistent performance for both transactional and analytical workloads.

Is this drive suitable for RAID configurations?

Yes, the SAS 12.0 Gbps interface and enterprise-class design make this drive suitable for RAID arrays. The 8.5ms average seek time and 128MB cache support the rapid access patterns typical of RAID operations, and the drive is compatible with standard 3.5-inch LFF server bays.

What is the average seek time and why does it matter?

The drive has an 8.5 millisecond average seek time, enabling rapid random access to data. This specification is critical for transactional databases and real-time applications where quick response times are essential for maintaining system performance and meeting service level agreements.

What spindle speed does this drive operate at?

The drive operates at 7200 RPM, balancing performance and power efficiency for sustained datacenter operations. This speed, combined with the 128MB cache and 8.5ms seek time, provides reliable throughput suitable for enterprise workloads across multiple concurrent operations.
