Western Digital Data Center Drives: What Do You Really Need to Know?

Data centers face rising demands forData centers face rising demands for secure storage. Western Digital¹⁵⁰, a leader in hard drives, often gets chosen—but is it always the best fit?

Western Digital data center drives include Ultrastar and Gold series HDDs and SSDs. Ultrastar drives are widely used for their reliability, endurance, and cost efficiency, making them suitable for enterprise workloads and cloud scale environments.

Many companies rely on Western Digital for storage solutions. Yet deciding which drive fits your unique application can be confusing. Data center operations are complex. I went through this process while choosing drives for a new project last year. Let me show you how to make sense of it.

What drives do data centers use?

Data centers must avoid downtime and data loss—that’s why only the most reliable drives get picked.

Most modern data centers use enterprise-grade HDDs and SSDs. Western Digital’sMost modern data centers use enterprise-grade HDDs and SSDs. Western Digital’s Ultrastar series is a popular choice, designed for 24/7 operation, high capacity, and better mean time between failure (MTBF)¹⁵⁰.

When I first started working on storage for a client’s data center, I realized that consumer drives just don’t last. They lack features like vibration tolerance and advanced error correction. Enterprise drives—like WD’s—offer SAS and SATA interfaces built for consistent, heavy workloads. Plus, their firmware focuses on maintaining data integrity.

Product comparison can be tricky. Here’s a quick breakdown:

Using enterprise drives like WD Ultrastar means fewer catastrophes and easier scaling. If reliability is your top goal, I suggest skipping consumer and NAS drives for data centers. I always check for advanced features like rotational vibration sensors, and end-to-end data protection, especially for mission-critical configs.

What is the Western Digital hard drive controversy?

Controversies disrupt trust. Western Digital faced backlash for shipping drives with misleading features.

The most visible controversy involved WD’s use of SMR (Shingled Magnetic Recording) in some drives marketed for NAS and RAID. Users discovered these drives The most visible controversy involved WD’s use of SMR (Shingled Magnetic Recording)¹⁵⁰ in some drives marketed for NAS and RAID. Users discovered these drives performed poorly for tasks with frequent rewrites, causing slowdowns and data risks.

I remember reading horror stories on forums from admins whose RAID rebuilds dragged on painfully. WD originally did not clearly label these SMR drives—especially in WD Red models—making it hard for buyers to know the risks. This led to drive dropouts in multi-drive arrays.

To help you understand why this matters, here’s how SMR and CMR (Conventional Magnetic Recording) stack up:

WD later fixed its product labeling and released drive lists clarifying SMR or CMR. If you’re buying for a data center where reliability matters, always check the recording type. When I select drives for critical applications, I use only CMR-based drives for performance and consistency.

Where does Western Digital manufacture hard drives?

Supply chain matters in reliability. WD makes drives in several countries, with facilities in Asia, North America, and Europe.

Most WD hard drive manufacturing happens in Thailand, Malaysia, and China. The company also has significantMost WD hard drive manufacturing¹⁵⁰ happens in Thailand, Malaysia, and China. The company also has significant R&D and assembly operations in the United States and other global locations to support design and logistics.

I once faced a shortage due to flooding in Thailand in 2011. That event triggered huge delays in the global supply of WD drives. Since then, I always check if a drive’s origin might affect availability or long-term service. WD’s global approach means better supply resilience, but regional events can disrupt things.

If you run a large project, source drives from suppliers who track their origin. Sometimes, firmware variations and support coverage hinge on where the drive was made. WD’s multi-country production helps meet demand, but always look up your batch’s details, especially if firmware and data security policies matter.

Here’s a summary table:

I always look for transparent documentation about the drive’s journey from factory to rack.
