Abstract
The described technology is generally directed towards allocating adjacent file parts to different virtual cylinder groups mapped to storage devices in a storage array system. According to an embodiment, a system can comprise a processor and computer executable components that can comprise a file allocating component that can allocate a first part of a file to a first logical data block mapped to a first physical data block on a first storage device, and allocate a second part of the file to a second logical data block mapped to a second physical data block on a second storage device, the allocating being based on the second physical data block being on a different storage device than the first physical data block. The components can also comprise a storage device controller that can write the first and second parts of the file to the first and second physical data blocks.
