Network attached storage (NAS) is the best way to keep your data backed up. Through this, you can also stream and access content from all the devices connected to the network. But common NAS systems are based around PCs, which can draw a large amount of current, especially as they’re powered on all the time.

In this tutorial I'm going to show you how you can convert your Raspberry Pi into an NAS. A Raspberry Pi is a low-powered device that draws only a fraction of power used by an actual NAS, and it’s also much cheaper. You lose some performance when you use a Raspberry Pi, but unless you want to stream very large files and want to stack up your hard drives in a raid configuration, the Raspberry Pi should work just fine.
