Pros and Cons

Your decision today may come down to the pros and cons of the Seagate Barracuda and the WD Blue.

Seagate Barracuda

Seagate BarraCuda

Pros:

  • We felt the price was good for the storage capacity when looking at $ per GB
  • The read/write speeds are generally excellent for both Windows and Mac
  • The installation is easy and certainly helped with the instructions on the Seagate website

Cons:

  • There is a lot of inconsistency with the quality of the product, some being dead on arrival, others only lasting a short period of time

WD Blue

WD Blue

Pros:

  • Better value for money when looking at the storage capacity and the $ per GB
  • Good transfer speeds considering the smaller cache
  • It’s really easy to use and overall quieter than the Seagate Barracuda

Cons:

  • There are no documents with it, nor screws or clips, so if you haven’t installed one before, you will need the website to help you

The Final Verdict

First of all, let’s recap on the similarities. The size and appearance of both are normal and didn’t affect our decision, although the Seagate Barracuda comes in two form factors which means it can be used in more PCs. The uses and compatibility are also the same, which makes both of these internal hard drives very versatile. It’s also nice that Seagate and Western Digital make the effort to follow RoHS compliancy.

In terms of speed, we were expecting the Seagate Barracuda to outshine the WD Blue because of the multi-tier caching technology and the larger cache. When actually using them, there was a slight difference but not a massive amount.

The software that comes with the WD Blue is good and it made transferring various files and apps an easy experience. At the same time, transferring data onto the Seagate Barracuda wasn’t complicated.

So, it was a very difficult decision. When we received the hard drives and considered the specifications, our initial thoughts were that the Seagate Barracuda was going to be the better internal hard drive, despite being more expensive. The main problem we have is that feedback we had from others was less than positive. There are always going to be the odd bad product but from Seagate, there were too many and the pros aren’t relevant when you receive a defective product.

With all of this in mind, we decided that the WD Blue was the better 4TB internal hard drive. It is an excellent value for money, and it was easy to install and use. It was quieter than the Seagate Barracuda, especially when the hard drive started to fill up. For the price, the transfer of data was very good. Overall, the WD is an excellent internal hard drive and above all, it is far more reliable.
