Abstract:
A storage apparatus manages collectively, as a group, a predetermined number of contiguous units of storage in the storage medium, selects a group, the number of the units of storage in a free state in the group satisfying an access performance set condition, when securing a storage region for storing write data, and sets a group in which the units of storage in a free state are distributed non-contiguously as a group to be selected, associates an address specified by a write access request and an address of the unit of storage in a free state in the selected group, and sequentially write the write data to the unit of storage in a free state included in the group.
