A data storage device includes storage media with multiple media zone attributes of storage performance. The storage device includes a data channel that is connectable to a host system. The data channel receives an object from the host system that has a requested storage attribute attached to the object. The storage device comprises an object-based storage interface that couples between the data channel and the storage media. The object-based storage interface schedules the object for storage in a selected zone of the multiple media zones based on the attributes and requested attributes.

Object-based data storage device

A data storage device comprises storage media including physical data blocks. The data storage device comprises a storage circuit. The storage circuit compresses a user data block into a compressed user data block before storing the compressed user data in one of the physical data blocks, leaving an unused block portion of the physical data block. The data storage device comprises a remapping circuit that remaps the unused block portion to an opportunistic block address. The data storage device comprises a circuit that stores data in the unused block portion.

Storage device with opportunistic address space

A data storage device includes a cumulative data histogram of lengths of idle times between foreground user service requests. The cumulative data histogram is updated with measured lengths of current idle times between successive user service requests. Background service request are scheduled following a user service request after a time delay that is controlled as a function of the cumulative data histogram and a calculated length of a busy time of the background service request.

Data storage device with histogram of idle time and scheduling of background and foreground jobs

An apparatus having a storage medium that includes a first region having a first characteristic and a second region having a second characteristic for storage of a plurality of data objects is disclosed. Each of the objects has an attribute that is determinative of the object being stored in either the first region or the second region.

Object based storage device with storage medium having varying media characteristics

A carrier and associated methodology for removably supporting a plurality of data storage devices as a multiple disc array in a distributed storage system. The carrier defines attachment features for fixing each of the data storage devices to the carrier preventing movement of the data storage devices in relation to the carrier in response to a vibration stimulus. This reduction in vibration stimulus allows the individual data storage devices in the multiple disc array to increase the number of track per storage area. This benefit can be used to increase capacity, increase performance and increase reliability of the multiple disc array.

Storage array with enhanced RVI suppression

A data storage array is provided such as for a distributed storage system or a consumer electronics device wherein increased data storage capacity is provided at the cost of increased power consumption in relation to industry standard power consumption rates. The array has a plurality of data storage devices, each having an actuator operably disposed in a data storing and retrieving relationship with a data storage medium. The data storage medium is rotated at a speed of substantially greater than 10,000 revolutions per minute, and each of the data storage mediums has a data storage capacity of substantially greater than 100 gigabytes. The increased heat created by the relatively faster rotation speed is handled through improved airflow made possible by a multiple device array constructed in accordance with embodiments of the present invention.

High speed and high capacity data storage array

A method for processing requests for information from a disc drive comprising: (a) receiving a plurality of requests, wherein each of the requests has application level information associated with it; (b) identifying a first group of the requests that fit within a time interval; (c) using a scheduling algorithm with disc information to schedule one of the requests in the first group; (d) adjusting the length of the time interval; (e) identifying another group of the requests that fit within the adjusted time interval; (f) using the scheduling algorithm to schedule one of the requests in the other group; and (g) repeating steps (d), (e) and (f). An apparatus that processes requests for information in accordance with the method is also provided.
