New RAID5 option for embedded systems
RAID5 divides the storage device into several partitions, one of which to hold parity information, which allows data recovery in case of a partition fail. It can be used on any storage medium and the parity information can be stored on the same storage device (in a separate partition) or on a separate device. The new add-on has a tiny memory footprint, typically using about 1kB of RAM and 3kB of Flash.
RAID5 is available as an additional option and as an alternative to RAID1. RAID1 uses 50% of the raw storage capacity for data security, whereas RAID5 is configurable, typically using 5% or less.
Being part of the emFile storage layer, the new add-on can also be used for USB mass storage as well as other applications.
