- and
- a second fingerprint table configured to store entries corresponding to data stored in the storage device which has been deemed less likely to be successfully deduplicated than other data stored in the storage device;
- and
- a storage controller coupled to the storage device, the storage controller configured to:
- at least one of update or maintain one or more attributes corresponding to usage of one or more data objects stored in the storage device;
