Raspberry Pi enthusiasts looking for extra storage may be interested in this excellent Raspberry Pi NAS storage solution created by Paul-Louis Ageneau. Constructed using a Raspberry Pi 2 model B with two hard disks connected with USB adapters all enclosed in a 3D printed case.
Functions of the Raspberry Pi NAS include the ability to use it as a file server for (FTP, NFS, SMB/CIFS…), streaming server for audio or video over your local network, personal web server to host a website, synchronise contacts or send files to people, local seedbox to download torrent files or a domotic hub for instance by adding a Zigbee USB dongle.
Paul-Louis explains more about the configuration of the Raspberry Pi mini PC to create the NAS desktop storage system. “The Raspberry Pi is actually not able to power the two drives over USB, since we would need 500mA per drive, so 1000mA overall, and the Pi can only supply 600mA over USB. There is a possible boot setting in /boot/config.txt called max_usb_current, which when set to 1 raises the maximum current intensity over USB to 1.2A, but since it is applied only during boot, our disks will still prevent the Pi to actually start properly. For this reason, we need a USB hub with a 2A adapter to power everything and connect the drives to the Pi. Backfeeding would be quite a bad idea, so the Pi needs to be connected to the hub twice, once as a device for power and once as the host.”
