[Key Features & Benefits]

Ultimate Cost-Effectiveness & Lower Cost per TB

This drive fits groups that watch costs and handle bulk HDD procurement. It provides 16TB of thick storage space. Yet, it comes at a low wholesale price. Groups can cut their Total Cost of Ownership (TCO) and cost per TB a lot. They do this without losing server speed.

Industrial-Grade Reliability & High MTBF

Engineers made it for round-the-clock heavy business tasks (up to 550TB/year). It uses Western Digital’s helium fill plan. This gives it a solid 2.5 million hours MTBF (Mean Time Between Failures). It also has strong Rotational Vibration Safeguard (RVS). Thus, it keeps a top low failure rate. This holds even in busy, packed server setups with many drives.

Robust Read/Write Performance for Big Data

A fast 7200 RPM motor powers it. A big cache buffer helps too. These ensure good sustained data transfer rates and small wait times. The drive works well for big, shared data tasks. It handles tough business apps with ease.

Rigorous Testing & Energy Efficiency

Each drive goes through tough check tests. Workers verify every part before shipping worldwide. This makes it ready to use right away. Also, the helium seal cuts air pull. As a result, it lowers power use and cool needs. This boosts energy savings in tight rack setups.

Comprehensive Data Protection & Integrity

It has several built-in safety tools for data. These include strong fix for errors and guard against power cuts. The drive keeps data safe and whole during sudden stops or hard settings. It protects key business info.
