What is the difference between the WD Colours? Understanding the WD HDD Rainbow

WD Colours Hard Drives

Why are some Hard Drives better than others for NAS, PCs, Surveillance and DataCenters?

Which Hard Drive Shall I buy which Drive do I need Hard Drive media has been around a long time – I mean a REALLY long time. Once it was deemed only for Desktop Computers but those days seem almost alien to us now that there are both Hard Drives and SSD‘s found almost every form of technology in the home, at work and around the world. With Hard Disk based media being found in some many different industries and vocations, it is easy to wonder why there isn’t just one really good kind of Hard Drive that can;t just be duplicated a million times, used everywhere and then we can all go home! The answer of course is that many, many tasks are so different that it would be impossible to create one kind of data storage media that was perfect for, say, recording video footage from a CCTV camera outside a shopping centre 24 hours a data and 7 days a week, and the same hard drive be suitable for a home based PC. Not withstanding that the Read and Writing performed in these too storage environments are drastically different, but how would you price these items? You would have to produce a rugged, heavy write Surveillance drive and sell it massively under-cost or be forced to make the poor student with his PC pay a whopping premium jsut to keep his Operating System afloat…

Ok, I understand why different drives exist. But what is with WD and all these colours?

WD Colours Hard Drives Many Hard Drive manufacturers have tried to simplify their HDD range for public and business consumption and the majority of them have fallen flat. Either because they find it hard to create simplistic tags for their range or because doing so could make the public aware that they may not need to spend the extra for a Enterprise Class Hard Drive, when they could get away with a basic PC HDD. The Western Digital came along and blew the market out of the water with it’s WD Colours (or WD Colors, there you go Americans… I care!) Range.

What is the WD Colours Range and how does it work?

Glad you asked. WD started reclassifying it’s hard drives a while back into coloured groups or Blue, Green, Black, Red, and more and have since prospered by ensuring that when a consumer or business needs to buy new HDD media, all they need do is find the colour that befits the storage environment they intend to use it in. Below is breakdown of the WD Colours and what market each applies to. I hope you find it useful and if you have any further questions about the WD Colours of HDD, please don’t hesitate to let me know in the comments.
