Attaching external storage to create a wireless NAS and using it for media-sharing as a DLNA server is one of the most popular DIY project for Raspberry Pi - the cheap mini-computer which has created a niche of it's own.

Renowned storage solution provider Western Digital has now came up with a USB powered hard-disk, specially designed for efficient and low power usage requirement of the Raspberry Pi. The custom-engineered WD PiDrive offers 314GB of storage space and is compatible with WD PiDrive accessories available at the WD Store.
