Abstract
The method begins with a processing unit receiving an encoded slice for storage. The method continues with the processing unit determining whether to store the encoded slice in one of a first set of memory devices or in one of a second set of memory devices based on metadata associated with the encoded slice, wherein the first set of memory devices are continually active and the second set of memory devices are selectively active. The method continues with the processing unit stores the encoded slice in the one of the second set of memory devices when the encoded slice is to be stored in the one of the second set of memory devices. The method continues with the processing unit de-activating the one of the second set of memory devices, in accordance with a deactivation protocol, after storing the encoded slice.
