What are the differences between the Western Digital drive colors?

When it comes to getting the job done right, it starts by having the right tool. Be sure to choose the right WD hard drive color for your needs.

Do you know the main differences between these drives? The primary uses of each drive is explained below.

WD Green

Green seems to be falling by the wayside more and more. Low energy-consuming, lower carbon footprint drives that can be left powered on for longer periods. Green is better in a RAID environment than WD black.

WD Black

The enterprise-level hard drive for reliable and long-term storage. It comes with a higher warranty which at last inspection was 5 years. 

WD Blue

This is a good all-around basic desktop storage drive but not good in RAID systems. It is best practice to boot from an SSD but use blue to store the general data files. Blue comes at a lower cost, lower 5,400 RPM speed, and a shorter 2-year warranty. This drive should not be used for highly critical data storage. There is a WD Blue Pro series as well. Blue is available in a hybrid variety. This will have an SSD that can be used to boot the system.

WD Purple

Designed as a surveillance drive for Closed-Circuit Television Systems (CCTV) and can be left on continually 24-7. It has a priority of its writing ability over its reading ability. Because of this, the write speed is higher than the read. The recording in this environment is ongoing but when there is a need to recall the data, you only need a small sample from a very specific time when a security incident occurred. There is a WD Purple Pro series having higher speeds and a better warranty.

WD Gold

This is the data center drive with good read and write speeds. 

WD Red

This is the most common of the WD drives. Can be in a RAID and is the choice for a NAS. Good all-around read and write speeds. There is a WD Red Pro series as well.
