Hard Drives

The hard drive is the trusty component used to store a lot of content. Available in sizes that can go all the way up to 16 TB (that's 16,000 GB) and different models are available from various vendors. Western Digital is one such company that offers both mechanical and solid-state storage but it can be a little confusing as to which one you should go with. Western Digital has the Blue, Black, Red, and Gold for mechanical drives. Here are all the specifications.

It's always recommended you go with an SSD for Windows 10 and other software to be installed on, leaving a mechanical drive free for storing games and files. The Western Digital Blue is the HDD built for the desktop, while the Black takes things to the next level for professionals and gamers. Enterprise and server owners have the Gold series to look through and the Red series of drives are specifically designed for NAS use.
