Compressed data is maintained in a plurality of strides of a redundant array of independent disks, wherein a stride is configurable to store a plurality of tracks. A request is received to write one or more tracks, and a determination is made as to whether all of the one or more tracks can be stored in one selected stride of the plurality of strides. In response to determining that all of the one or more tracks can be stored in the one selected stride, the one or more tracks are written in the one selected stride of the plurality of strides.
