What are the performance specs?

7200 RPM spindle speed, 256MB cache, and sustained transfer rates up to 255MB/s. These deliver reliable throughput for bulk data applications, with average latency around 4.16ms, suiting 24x7 workloads in cloud and HPC environments.

What is the operating temperature range?

5°C to 60°C, allowing deployment in varied datacenter conditions. This wide range reduces cooling requirements and ensures stability during high ambient temperatures common in dense server racks.

What power does it require?

+12V and +5V supplies, optimized via PowerBalance technology for efficiency. This supports scalable power budgets in large enterprise deployments without excessive consumption.

Is it suitable for 24x7 operation?

Yes, designed for 24x7 enterprise use in bulk data storage, hyperscale, and RAID. Features like CMR recording and robust vibration tolerance ensure reliability over 8760 hours/year.

What form factor and technology does it use?

3.5-inch form factor with Conventional Magnetic Recording (CMR). This standard size fits rackmount servers, while CMR provides predictable performance unlike SMR drives.
