The Go programming language defines simple I/O interfaces that any data type may implement. In this paper we introduce a Go package that allows arbitrary implementations of these interfaces to be composed into RAID-like redundant (and/or) high-performance striped arrays. The package also allows spares to be added for fail-over functionality. The package is focused on providing a highly available write setting that tolerates multiple failures but can always receive data as long as a single redundant path exists. This is achieved by allowing reads to become unavailable in the presence of failures that cannot be solved while the array is operating.

The package is highly concurrent and parallelized and exploits the Go programming language's built-in light-weight concurrency features.
