Abstract
For performing efficient full-stride copy source-to-target operations in a computing storage environment by a processor device, pursuant to a destage operation, a determination is made whether to destage a full stride or one track of data on a target volume by comparing a counted number of modified tracks for the full stride against a predetermined threshold.
