At one time, WD wisely divided its range of drives, using a colour scheme that was understandable to all people. According to WD, the "black" hard drives are designed with gamers and fast laptop owners in mind, the "purple" hard drives are designed for use in video surveillance systems, and the "red" and "gold" hard drives were created with an eye on data centers and server rooms. whose work never stops. Well, the classic hard drives from the Blue line are best suited for the consumer segment,


WD Blue is one of the most affordable 3.5 format consumer SATA HDDs. They are designed for use as part of multi-purpose home and office configurations at the most affordable cost. A good alternative would be to use an inexpensive WD Blue as the primary game library storage in an inexpensive gaming PC. With low power consumption and the use of the industry standard SATA3 port, which is backwards compatible with the first and second generations of this interface, WD Blue hard drives are suitable for installation in modern workstations and older PCs or laptops.

The WD Blue series range offers several popular models from 320 GB to 6 TB to choose from. Most of them run at 7,200 rpm. Options with a spindle speed of 5,600 revolutions are quite rare on sale. The amount of cache memory can be in the range from 32 to 128 MB. It depends on the model of a particular drive and its volume. It is also worth noting that later WD5000AZLX caliber drives introduced NoTouch contactless reading technology, which increases the degree of data protection due to the safe location of the write head relative to the surface of the drive.
