Western Digital Red (WD30EFRX) 3 TB NAS Hard Disk Drive

The popularity of Network-Attached Storage (NAS) devices is rapidly ramping up in both small businesses and homes, fueled by their usefulness and their increasing affordability. This surge in interest has led Western Digital to add a new family of hard disk drives - the WD Red family of NAS hard disk drives, even as Seagate drops production of 5,400 RPM desktop hard disk drives.

Of course, this begs the question - why choose a WD Red when the WD Green (formerly known as the WD Caviar Green) hard disk drive is also a low-powered, slower-spinning hard disk drive? It mainly lies in the WD NASware firmware, its comprehensive compatibility testing with common NAS systems and a dedicated WD Red 24x7 support line.

Today, we are going to take a look at Western Digital's top Red drive - the WD30EFRX with 3 TB of storage capacity. Here are its key features :

  • Exclusive NASware Technology - WD's exclusive NASware technology improves NAS storage performance by reducing common hard drive concerns in NAS systems including concerns for things like compatibility, integration, upgrade ability, reliability and cost of ownership that are experienced with a hard drive designed for desktop computers.

  • NAS Compatibility - Advanced firmware technology built into every WD Red drive, enables seamless integration, robust data protection and optimal performance for systems operating in NAS and RAID environments.

  • 3D Active Balance Plus - This enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multidrive system, reduce the hard drive life span, and degrade the performance over time.

  • Enhanced Reliability - With a 35% MTBF improvement over standard desktop drives, the WD Red drive is designed and manufactured to be a more reliable and robust solution.

  • Energy Efficient - Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on 24x7 NAS environments.

  • Premium Support - Exclusively for WD Red drive customers, a free dedicated 24/7 support line is available in English. Other regional support hours vary.

  • Longer Warranty Coverage - The WD Red drive is backed by a 3-year limited warranty for greater peace of mind.

Now, let's take a closer look at this big daddy of the new WD Red family of hard disk drives!

Our Review System

Tech ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a multi-tier review system.

This review system is designed to allow you to quickly receive information on the latest hardware or software. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
