WD Blue vs Black

As one of the most trusted hard drive brands, Western Digital has launched various kinds of hard drives. Many computer users prefer purchasing this brand to replace the old and falling hard drive. But the upset thing is that more choices lead to rising hesitation.

Further reading:

Western Digital Corporation is a leading manufacturer of computer hardware equipment. This company not only sells hardware to computer manufacturers, but also serves consumer markets directly through its product replacement items and add-on data storage products.

In the late 1990s, WD ranked 3rd in terms of drive shipped and market share. In 2019, this brand is also at the head of the market.

Since many users are bothered by choosing WD Black or WD Blue, this post shows the comparison between these two kinds of hard drives to help you select a proper hard drive for your deceives.

Note: It is hard to say which hard drive is best, because the valuation depends on the intended use. It is imperative to keep this in mind before buying. 

WD Blue Drive

WD Blue is a kind of hard drive with the blue cover as the following image shows. It looks pretty.

Designed for use as primary drives in notebooks and external enclosures, this drive hands the stuff that requires a lot of storage in a snap, including high-resolution photos, 4K videos, music collections, cutting edge-edge games, and other important files.

This hard drive also features data density, which indicates that the travel requirement on the header is minimized and the seek time also is reduced.

Now, let’s see some essential specifications of the WD Blue Drive:

  • Capacity range: 500GB – 6TB;
  • Interface: SATA 6GB/s;
  • Form factor: 2.5-inch and 3.5-inch;
  • Sustained transfer speed: 147MB/s to 180 MB/s;
  • Cache: 64MB (it is more than enough for higher-speed burst operations);
  • RPM class: 5,400 RPM and 7,200 RPM;
  • Target consumer: general users;
  • Warranty: 2 years;
  • Price: $43.99 - $138.99 (on Amazon);

The above information about this hard drive maybe not enough, and you can see the following picture from WD to get more detailed information:

Wrapping up the features of WD Blue, we conclude that this drive is the best cost-to-performance ratio and it is wise to be used for basic purposes. To seek an ideal combination of speed and capacity, you can pair the WD Blue hard drive with a WD SSD.

Note: Storing and accessing important files frequently on this hard drive will cause it not to deliver the reliability that you would expect.

WD Black Drive

The WD Black hard drive also looks pretty as the following image shows. This drive is designed to enhance the PC experience, for example, it is perfect for high-performance applications like photo or video editing and gaming.

WD Black Drive

As the best consumer HDD on the market, this drive is intended to be the top of the WD consumer-grade drives. The WD Black is aimed at a high capacity with the fastest throughput.

As the above content says that WD Blue boasts high speed due to data density, and this made it be a bit faster sequentially than the Blck in passing days. But the newest 6TB WD Black changes the situation.

The 6TB WD Black features 5x 1.2TB platters and 10 read/write heads. This design maximizes data density per platter and helps minimize the travel of the heads.

Now, let’s see some essential specifications related to WD Black:

  • Capacity range: 500GB to 6TB;
  • Interface: SATA 6GB/s;
  • Form factor: 2.5 inches and 3.5 inches;
  • Sustained transfer speed: 202MB/s to 227MB/s (this speed offered with the WD Black will ensure that you will receive the best performance while using a standard HDD drive);
  • Cache: 64MB to 256MB;
  • RPM class: 7,200 RMP;
  • Target consumer: graphic designers, gamers, and other resource-intensive users.
  • Warranty: 5 years (this makes for a more tempting option for production rigs and performance computing);
  • Price: $54.99 – $257.99 (on Amazon)

There is also a sheet of the information of WD Black hard drive and you can learn it more.

Wrapping up all the above information about WD Black, we conclude that the WD Black boasts higher performance but it is more expensive than the WD Blue. But note there is the price drop on the WD Black drive over the last couple years and the current price of this drive is quite attracting.

Another comparison between these WD drives you need to learn about is that the WD Black adopts a beefier chassis than WD Blue as a part of its vibration control. As we know, an HDD uses its header to help us find the data we want. With the beefier chassis handing high-speed fan vibration and odd mounting orientation, the WD Black will bring fewer chances of read errors.

Furthermore, the WD Black also forgoes the energy and sound louder. In other words, this drive consumes more power and sounds nosier when working than the WD Blue.

According to Western Digital, there is not any real technological difference between the two drives in terms of the processing and caching architecture while the differences are platter density, platter count, and the chassis.

After seeing Western Digital Blue vs Black, have you decided to pick the Blue or the Black? Whether you decide to buy the Black or Blue, one thing that needs to be noted is that failing to use the proper hard drive can lead to data loss or hard drive failure.
