4 tb = 7200 rpm, nice cache size too, 4 heads on the platter means that the i/o is always flashing

Great value for the overall cost




Very quiet Runs cool 64MB cache Plenty fast SATA 3.0 interface 3 year warranty

I had a problem with an order but this seller worked with me to address the issue appropriately and in a fast manner. I was very pleased with their customer service and will definitely do more business with them in the future. I had a great experience.

Easy to plug in and format. I have had many WD drives over the years and they have all been reliable. Never had one fail. I like the 256MB of ram, but would prefer 512MB for this size of a drive.

- got what I ordered - These guys really walk the walk and talk the talk. - I would order from them again without any hesitation

- Extremely Reliable - Extremely Durable - Fast for HDDs

So far so good



The best feature of this drive is how quiet it is. In my personal testing the performance is equal to or better than the x20 and it is a little bit less expensive. Going forward this will be my goto 20 tb hard drive. Hopefully its reliable as the x20 going forward.

I bought one months ago and just got another. They work great as NAS storage. Although not as fast as the WD-BLACK line, they are faster than cheaper drives. They are also quieter than my other 4TB drives.



Been fast and reliable for me. Have not had one die yet here. Out if the gold.

It Works. no bad sectors
