Network-attached storage (NAS) devices have grown in popularity for both businesses and home users. In the business setting it has allowed a cheaper method of shared storage than a dedicated file server. For home users it has allowed a convenient place for multiple users to share files securely.
Many of these NAS devices contain multiple hard disk drives. They start from the two disk RAID-0 found in many home user NAS devices, like the the Netgear ReadyNAS Duo and range to the 4+ disk arrays found in NAS devices like the Buffalo TeraStation or the Lacie 5Big Network.
Most NAS units are based on a Linux operating system and file system. These include ext2/3/4, XFS, and Resier FS. Rebuilding each of these filesystems varies in complexity.
Typical failures seen in NAS storage devices:
| Lost ‘Shares’ | Multiple HDD failure |
| RAID controller failure | Bad rebuild |
| Corrupt filesystem | Damaged RAID configuration |
| Intermittent drive failure | Failed firmware upgrade |
