A technique for achieving consistent read latency from an array of non-volatile solid-state memories involves an external entity determining the “busy” or “not busy” status of non-volatile solid-state memory elements in a RAID group. An external data layout engine then uses parity based RAID data reconstruction to avoid having to read from any memory element that is busy in a RAID group, along with careful scheduling of writes and erasures.
