**Q: Whats the difference between this and the red plus?**
A: WD Blue HDDs are mainly used for general purpose storage, they are great all-rounders, and an average user can’t go wrong with Blue.

WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap.

WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs.

WD Red is a NAS drive. It’s optimized for NAS systems.

WD Purple is for surveillance. Advised for 24/7 operation.

WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications.
