Design and Build:

WD is well known for their capable, and long lasting drives. This only got better and better as technology advanced. Today WD sports numerous HDD types, each specializing in unique storage environments.

WD Blue; the perfect storage device to store and house all those important and not so important files. Whether they are pictures or photos, music, or memorable video clips. The WD Blue was made to take care of these.

The actual drive does not sport any fancy features or visuals, It looks pretty much the same as any other standard HDD, except for the technical details and WD Blue Logo on it. There is absolutely nothing wrong with this. It will be tucked into your tower, invisible to the eye. After all, it is what’s on the inside that matters here.

WD has always used high quality components to make their drives. The longevity of these drives attests to that fact.
