Western Digital, also known as WD, develops hard drives, SSDs, and NAS. The WD range includes both internal and external hard drives. Their external hard drives are available in 2.5 inches for on the go and 3.5 inches for your desk. You can use them as soon as you take them out of the box. Internal hard drives are also available in 2.5 and 3.5 inches, but are designed for different usage situations. SSDs are a lot faster than hard drives, both internal and external. Some SSDs, such as M.2 NVMe SSDs, are up to 20 times faster. Do you prefer a wireless storage space that you can access via your network? Choose a WD NAS to create your own private cloud.
