Techniques for data storage using disk drives. To conserve power and reduce heat generation so that higher packaging density is possible, only some of the disk drives in an array may be powered on at any one time. Disk accesses may then be scheduled so that appropriate drives are powered on and off at appropriate times. In addition, various levels of storage services may be provided depending, for example, upon how accessible the drives are to individual clients and upon a level of data redundancy provided. Another advantage includes off-loading of tasks to a controller or processor included within the disk drives themselves. For example, the disk drives themselves may compute error detection or error correction representations and perform data integrity checks based on those representations. Failure simulation may also be performed to verify the ability to recover lost data and the disk drives may be used to convert the data into general formats that may be expected to be more easily read in the future.
