1. A computer-implemented method comprising:
determining, in response to a request to delete a first data slice managed by a storage system, that a record for the first data slice exists in a catalog of the object-based storage system;
obtaining a pointer for the first data slice, the pointer referencing a location on a physical storage device as containing the first data slice;
determining that the pointer exclusively references a single data slice stored at the location on the physical storage device; and
performing a no-seek delete of the first data slice in response to the determining that the record for the first data slice exists in the catalog of the storage system and the determining that the pointer exclusively references the single data slice stored at the location on the physical storage device.
