Recently, consumer NAS servers are gaining more and more popularity. A modern NAS is a self-sufficient "smart" device, a kind of mini-server that stores tens of gigabytes on pre-installed hard drives and is ready to provide access to them at any time. Using a dedicated processor, RAM and its own highly specialized operating system, a home NAS server can connect directly to a local network, supports smartphone control, and can work as a dedicated media server or a reliable database for a photographer, designer, artist or videographer.


As a basis for the red line, WD used models from the WD Blue consumer series. For example, the Red SA500 model is the twin brother of the WD Blue 3D drive: it has the same connection interface, the same 2.5 form factor, and the same Marvell 88SS1074 memory controller. But at the same time, the TWB indicator, which indicates the time between failures, is much higher in Red drives. For example, the 500 GB WD Red model boasts a 350 TB rewrite resource, which is the best indicator among all the company's consumer models. It's not for nothing that WD claims that such a device is ready for loading 24/7.

Also in this series, the technology of turning off the power when there is no activity is used, which allows you to save a little on power and slightly extend the life cycle of the drive. Well, given the relationship with the WD Blue series, the Red models can be useful outside of the server rooms. Given WD Red's focus on increased reliability and durability, it makes sense to use this SSD in desktop PCs and laptops for professional work.
