Western Digital’s HDD series currently has six colors: Blue, Green, Red, Purple, Black, and Gold. At first glance, all of these colors could be confusing. That’s why we have created this article to explain you the difference.
All of these HDDs are made for different purposes, so it’s important to choose the best fit for your needs. Imagine footwear – you can walk with both sandals and winter boots, that’s true. But it may be wiser and more efficient to use sandals when you’re in beach and boots when there is snow. The same thing goes with HDDs.
Of course, you can use what ever hard drive you want on your computer and it will run fine. For example, WD gold as your primary drive. However, this would be an overkill as you probably wouldn’t use its full potential, just spend some extra cash. Getting WD Black or Blue instead would be much wiser. Therefore, spend a minute or two and research which hard drive is the best choice for you.
WD Blue offers reliability and performance for everyday users. Blues are great all-rounders made for general use. Price on these things is also great making them a good deal. You can get a WD blue with capacities ranging from 250 GB to 6 TB. RPMs vary – there are models with 5400 RPM and 7200 RPM.
WD Blue is a good drive for storing anything you need, whether it’s gaming or just some music and pictures. It also sits in the sweet spot of performance and price, making it great. If you can’t decide which Hard Drive to get, just buy WD Blue, you can’t go wrong with this.

We won’t get too detailed with WD Green as WD Blue has taken Greens place. Everyone chooses WD Blue instead of green. WD Green is slightly more power efficient than WD Blue. However, this difference is hardly noticeable. WD Green also lacks some performance compared with WD Blue. It’s just not worth it. Get Blue instead.
Nowadays Western Digital has stopped manufacturing WD Green hard drives. And now under the name “WD Green” they manufacture SATA and M.2 SSDs.[amazon_link asins=’B06XR3DDCB,B00DXOJJQQ,B00165RLL4′ template=’MyCopyOf-ProductGrid’ store=’ishddmag-20′ marketplace=’US’ link_id=’e08093b7-7350-11e7-8d5c-319e67a1c0d8′]
For Max performance, WD Black is the best choice. These drives feature a storage capacity ranging from 1TB to 6TB. These HDDs are great for gamers and workstation PCs as they offer performance and reliability.
WD Black 6TB has a 128MB cache, which is way more than Blue series 64MB. All WD Black versions come with standard RPM of 7200rpm and have a 5-year warranty. However, because of higher performance, these drives may heat up a bit more than other series and are a bit louder. To make it simple, WD Black is a performance drive.

WD Red AND Red Pro
The WD Red is built to be slotted inside a NAS (Network Assisted Storage). WD Red is compatible all most popular NAS systems. Others members of WD family can’t do this. WD Red capacity ranges from a minimum of 750 GB capacity model up to the 8 TB version. RAID configuration is also supported.
One thing that you should know – Red family excels more into the read performance than write. That’s only normal for NAS Hard drive. All data is stored through a network, so multiple users connect at the same time and read some data.
Note: There are two versions of WD RED – Pro and standard.

One word that characterizes WD Purple family the best is “surveillance.” This means that WD Purple is capable of withstanding operation of 24/7. Mostly these drives will be used for storing and recording videos. For example, in security systems.
If WD Red excels at read speed, then the Purple does exactly opposite – it has high write speeds. These drives feature a technology called AllFrame that minimizes errors in saving videos. You can get the WD Purple in a wide range of capacities starting from 500 GB up to 8 TB.
