Connectivity and Compatibility

These two PC hard drives come with a SATA 6.0Gb/s interface, which is now known as SATA III. The WD Blue and the WD Black are compatible with all in one PCs and desktops. They will run with Windows and Mac, but you might have to format the hard drive for Mac. You will need to make sure your computer has a 3.5” unused hard drive bay or use a SATA adapter.

RoHS Compliant

The WD Blue and the WD Black are both RoHS compliant, meaning they comply with the Restriction of Hazardous Substances in electrical and electronic products.

Apart from this, and the fact that they both have 4TB of storage space, the WD Blue and the WD Black have nothing else in common. So, let’s see how they are different.

Differences Between WD Blue and WD Black

Appearance

These hard drives are amazing because they look like SSD cards, but they have the storage space of hard drives.

WD Blue

As the name implies, this 4TB PC hard drive is blue. It is just 5.79 x 4 x 1.03 inches and it weighs 1.52 pounds.

We do like how Western Digital keeps things simple. The black 4TB PC hard drive measures the same as the WD Blue but it weighs a fraction more 1.66 pounds.

WD Blue Comparison

For those that don’t know, inside a hard drive there, is a small disk that spins around. The RPM is the number of revolutions or spins the disk makes in a minute. The more spins, the faster your hard drive.

WD Blue

WD Black

This has a faster hard drive, with 7,200RPM. This means it will deliver data approximately 33% faster than the WD Blue.

The Cache

WD Black Review

Imagine the cache of a hard drive as the temporary storage place while data is being written into the permanent storage location.

WD Blue

With this PC hard drive, you have a cache of 64MB, which is fairly average although it would be nice to see a little more.

WD Black

Now you can experience a 2X DRAM 256MB cache. The increased cache means your loading time will be faster.

Unique Features

WD Blue Review

While the WD Blue and the WD Black are both 4TB PC hard drives, they still have a few features that are incomparable.

WD Blue

It comes with Acronis True Image WD Edition cloning software. This will allow you to easily crop your old data onto the new hard drive. It also has IntelliSeek. This calculates the optimum seek speeds to lower the power consumption, noise levels, and vibrations.

WD Black

The dual-core processing allows for twice the processing capacity which means you can enjoy maximum drive experience. This is ideal, especially for loading games. It also has StableTrac, which secures the motor shaft and increases its reliability. It does this by reducing the impact of the vibrations of the components.

Value for Money

Western Digital Blue

It’s hard to say what a good price is without comparing each brand individually and seeing what its 4TB PC hard drive has to offer. Prices will range from $70 to $150. Most hard drives will come with at least a 1-year warranty.

WD Blue

This comes at an excellent price for such a well-known brand at the lower end of average. The hard drive has undergone strict quality control testing in WD’s FIT lab and comes with a 2-year limited warranty.

WD Black

It is quite a bit more expensive considering it is still a 4TB hard drive. WD has also put this hard drive through strenuous and aggressive internal testing and it comes with an impressive 5-year limited warranty.

Pros and Cons

Before we offer our final verdict on the WD Blue and the WD Black, we will look at a few pros and cons.

WD Blue

WD Blue

Pros:

  • You won’t hear any noise or experience overheating
  • It is incredibly reliable; you will be able to run it for years without any issues
  • The installation takes no time and isn’t complicated

Cons:

  • There is no documentation with the hard drive, you will have to do a little online research

WD Black

WD Black

  • It is incredibly fast at transferring files, photos and videos
  • It is great for gaming and professional use
  • A good option for Mac users and takes very little formatting

Cons:

  • Again, no documentation and it is very loud

The Final Verdict

The one negative that we want to get out of the way is the lack of documentation, cables, screws, and clips. You will need to buy a SATA cable and depending on your PC, either screws or clips. You could almost understand this for the WD Blue, but for the additional cost of the WD Black, it should come with at least a SATA cable.

There are a lot of things that we considered a tie. First, we had the appearance. They are the same size; the weight is practically the same and you won’t see it, so the color is irrelevant. The unique features were also a tie. This is because it will often depend on what your intentions are. The dual-core processing is definitely an advantage for speed. The StableTrac technology looks great on paper, but when using the WD Black, there was a very noticeable noise. The features of the WD Blue are good but if you are looking for speed, it’s no match for the dual-core processing of the WD Black. Then, there is the value for money. While the WD Black is more expensive, it is a lot faster and the warranty is for much longer.

The WD Blue is a great high performing hard drive for PCs and if you are on a budget, you can’t go wrong with it. It is reliable, durable, easy to install and is still fast enough for normal use.

In the end, and after great deliberation, we chose the WD Black. The faster RPM and the larger cache combined with the dual-core processing makes this PC hard drive amazingly fast. This is a great benefit for everyone, particularly for those who want a hard drive for professional use. Although it is more expensive, it will last for an incredibly long time and a 5-year warranty is industry-leading. For the quality on the WD Black, the speed, and reliability, we felt that it was very much worth the price tag it comes with.
