Abstract
A method and apparatus for deferring media writes for emulation drives are provided. By deferring media writes using non-volatile storage, the performance penalty associated with RMW operations may be minimized. Deferring writes may allow the RMW operations to be done while the disk drive is idle. Further, deferring writes may also allow data blocks to be accumulated over time, allowing a full (4K) disk drive block size to be written with a simple write operation, thus making a RMW unnecessary.
