Providing I/O operations to a storage device includes selecting a portion of original I/O operations based on a first set of criteria, determining whether to subdivide each of the portion of original I/O operations that are selected according to a second set of criteria different than the first set of criteria, and converting each of the original I/O operations selected for subdivision into a plurality of subdivided I/O operations for different portions of data for a corresponding one of the original I/O operations, where at least two of the different portions are from a single track of data on the storage device. The first set of criteria may include whether the I/O operations are for multiple tracks of data and whether the storage device supports subdividing a single track. The second set of criteria may include determining a measured amount of performance improvement for previous subdivision operations.
