The Final Verdict

We really do want the Seagate to win. It has some fantastic technology two different form factors and a great price, especially when you think of the 5-year limited warranty. Seagate still has a significant number of problems with quality control and we are not sure if it’s worth it for a few dollars less.

The WD Black is not much more expensive than the Seagate Firecuda, but as you know that the brand name is more reliable. The speed of transferring data was brilliant and for that, we could forgive the slight noise. Between the cache, the RPM, and the dual-core processing, it isn’t just fast, but it really improves the speed of your PC and your games. Overall, we found the WD Black to have the right amount of everything for a good price making it the superior storage solution.
