Product Features
Technical Overview
This 3.5" internal hard drive utilizes a SATA interface with SATA/600 (6 Gb/s) signaling for optimal burst performance in NAS configurations. The 7200 RPM spindle speed reduces latency compared to lower-RPM drives, making it suitable for applications requiring quicker access to large files.
The 512 MB cache buffer acts as a high-speed data reservoir, temporarily storing frequently accessed information to accelerate read operations and smooth write performance during sustained transfers.
Relevant factors for this section include Storage Capacity, Spindle Speed (rpm), Buffer. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.

FAQ
What is the storage capacity of this Western Digital hard drive?
This Western Digital Red Pro drive offers 12 terabytes (12TB) of storage capacity. This substantial space can accommodate millions of high-resolution images, hundreds of hours of HD video content, or extensive music libraries, making it suitable for business data storage, media archives, and NAS deployments requiring high-capacity solutions.
What form factor does this hard drive use?
The drive utilizes a 3.5-inch form factor, which is the standard size for desktop hard drives and many NAS enclosures. This physical dimension ensures compatibility with most multi-bay NAS systems, desktop computer drive bays, and storage arrays designed for 3.5-inch drives.
What is the spindle speed (RPM) of this hard drive?
This Western Digital Red Pro drive operates at 7200 revolutions per minute (RPM). This higher spindle speed compared to 5400 RPM drives reduces latency and improves data access times, making it better suited for applications requiring responsive performance in NAS environments with multiple simultaneous users.
What interface does this hard drive use for connectivity?
The drive features a SATA interface with SATA/600 (6 Gb/s) signaling standard. This interface provides maximum compatibility with modern NAS enclosures, motherboards, and storage controllers while delivering the bandwidth needed for optimal burst performance during data transfers.
How much cache does this hard drive have?
This drive includes a 512 megabyte (MB) cache buffer. This substantial cache acts as high-speed temporary storage for frequently accessed data, accelerating read operations and helping to maintain consistent write performance during sustained file transfers in NAS environments.
Is this hard drive suitable for NAS deployments?
Yes, the Western Digital Red Pro series is specifically engineered for network-attached storage environments. These drives include features like vibration compensation technology for stability in multi-drive systems and are designed for 24/7 operation, making them ideal for NAS deployments in business, creative, and home office settings.
