Overview of WD Red and WD Blue

WD Red Hard Drive

WD Red hard drives are designed for NAS solutions and come with large storage sizes and a red cover, as shown in the image.

Western Digital Red vs Blue: What Are the Differences and Which One Is better?

WD Red vs Blue What Are the Differences and Which One Is better

Form Factor & Interface

When it comes to form factor, both of them provide the same choices with SATA 6 Gb/s interface and 2.5-inch, 3.5-inch, and M.2 2280 form factor.


Hard drive capacity is a key factor when selecting a hard drive. So, the second difference between WD Red and WD Blue is the hard drive capacity. Both WD Red and WD Blue come with large hard drive capacity, but there are also some differences due to different form factors. You can look at the following chart to know the hard drive capacity differences.

From the above chart, you can learn that both of them provide large storage sizes, allowing you to save a lot of files, high-resolution photos, 4k videos, etc. But the WD Blue hard drive provides more hard drive capacity ranges, which will satisfy more different demands of different people and can be used in more situations. In particular, with small sizes such as 500GB or 1TB, it would be more suitable for common PC users.


The transfer rate is the third distinction we want to make between WD Red and WD Blue. Western Digital’s official website states that the WD Red can transmit data at a rate of up to 180MB/s (6TB model). WD Blue can transport data at a rate of up to 175 MB/s (6TB model).

Since the magnetic heads move in the radial directions of the platters and the platters rotate at a high speed of several thousand revolutions per minute, RPM (Revolutions per minute) will also have an impact on the hard drive’s performance. The magnetic heads can then be placed on the platter at a specific location for reading and writing data as a consequence.

However, the RPM of WD Red and WD Blue hard drives varies. All 2.5-inch WD Blue and WD Red models have hard drives with a 5400 rpm class. There is a little difference with the 3.5-inch WD Blue hard disk. The WD Blue 500GB and 1TB variants have 7200 rpm classes, whereas the left model has 5400 rpm classes.

Therefore, it is clear from the facts above that there are no significant variations between the transfer rates of WD Red and WD Blue hard drives. Using MiniTool Partition Wizard, you can also evaluate the hard drive’s performance.

Reliability and Warranty

WD Red hard drive comes with a limited warranty of 3 years, unlike Blue which comes with 5 years warranty. In another case, it can monitor the health of the drive, which comes in a free downloadable WD SSD dashboard.


You can find the WD Red here where there seems to always be consistent availability.

For the features and capabilities, the WD Blue has, we think the price is fantastic value for money!
