Abstract (en)

[origin: WO0067250A2] The present invention is related to methods and systems for providing different stripe sizes for different zones for at least a first of a plurality of mirrored drives to improve data rates. The first drive has a plurality of zones. In one embodiment, a first stripe size is selected for a first zone, and a second stripe is selected for a second zone. The said second stripe size is different than said first stripe size.

[origin: WO0067250A2] A method and system for providing different stripe sizes for different zones for at least a first of a plurality of mirrored drives (122, 124, 126) to improve data rates. The first drive has a plurality of zones. In one embodiment, a first stripe size is selected for a first zone, and a second stripe is selected for a second zone. The second stripe size is different from that of the first stripe.
