APPARATUS AND METHOD COMBINING LOWER-ENDURANCE/PERFORMANCE AND HIGHER-ENDURANCE/PERFORMANCE INFORMATION STORAGE TO SUPPORT DATA PROCESSING

摘要

An information storage arrangement that combines higher-endurance (or performance) storage with lower-endurance (or performance) storage is managed in a manner that makes judicious use of the lower-endurance (or performance) storage. It is therefore possible to exploit the economic advantage associated with lower- endurance (or performance) storage, while also avoiding storage capacity losses that would otherwise be associated with lower-endurance (or performance) storage.
