Network attached storage (NAS) comes in a variety of configurations from: single drive, RAID 0, RAID 1, JBOD and RAID 5. In addition to a variety of configurations manufacturers may use a variety of files systems configurations and may use software and or hardware to control RAID functions. NAS devices use a stripped down version of file systems. NAS devices will typically use an “Open Source Linux” based file system as there are a variety of them to choose from including: Free BSD, EXT 2 EXT3, EXT4, ReiserFS and XFS.
Hard drives in RAID NAS devices operate the same as a standalone hard drive but may have firmware, vibration tolerances, limitation of extended read retries and other tuning suited for use in a RAID or more specifically a RAID 5 environment. Extended read retries on slow or failing sectors in a RAID 5 NAS can be more quickly and efficiently recovered from redundant RAID 5 recourse and are therefore disabled.
Through two decades servicing our customer’s data recovery needs, we have encountered and successfully recovered data from almost every possible scenario pertaining to NAS failures. Many failures in RAID configurations or RAID 5 NAS devices are due to excessive heat. In many cases we have found the drive(s) in the middle of the RAID are the first to fail. Although, NAS devices can be used as a backup they are not a backup unless another set of redundant data is stored elsewhere. While a NAS device configured as a RAID 5 or RAID 1 can lose one drive and continue operations in a degraded state, should another drive become problematic or fail, the entire array will then fail as well. In some cases a NAS running in a degraded RAID 5 or RAID 1 may go unnoticed until a second drive fails.
