2. WD Blue
This is one is kind of interesting. I remember WD Blue sort of being like the de facto standard internal hard drive for a very long time. The newer WD Blue comes with a built-in SSD, it’s kind of a hybrid. This is going to give you enhanced speed on regularly accessed stuff. They are general purpose all-rounders. But they are intended for average users who are a little bit less intense.
3. WD Red
These are optimized for network-attached storage (NAS) as the intended use case. You attach this drive to your NAS system and it allows you to access data locally on the network, as well as share it with other people. You can also access that data not just locally, but also via the web. Also, they support raid configurations.
The Red family excels more in the read operations than write operations. Exactly what is expected for NAS storage, because data is stored on a network and multiple users will connect at the same time to read it. WD Red has two versions; WD Red Pro and WD Red Standard.

On the front, it says “24/7 reliability”, Intended for everything up to HD video. WD Purple has high write speeds which is the opposite of WD Red. Also, these have the all frame technology which ensures minimal errors in video storage.
