摘要： A disk is divided into K angular regions. A log write request is replicated K times and K number of identical log writes are issued to the disk to be written to each of the angular regions of the log. Upon completion of the first write, the application requesting the log write is informed of its completion resulting in a reduction of rotational latency by a factor of K.
摘要翻译： 磁盘分为K个角度区域。 日志写入请求被复制K次，K个相同的日志写入被发送到要写入日志的每个角度区域的磁盘。 在完成第一次写入之后，向应用程序请求日志写入通知其完成，导致旋转等待时间减少K倍。

摘要： A method and apparatus for preserving contents of a volatile memory when a main (e.g., AC) power source is disconnected. The apparatus comprises flash memory, a controller for writing to the flash memory and a temporary power source. The temporary power source may be a relatively low power battery or supercapacitor. The apparatus is removably attached to a computing device (e.g., via a USB port). When main power of the device is disconnected, the temporary power source provides power for the apparatus, the volatile memory containing data to be safeguarded, and sufficient processing resources to transfer the data. For example, an auxiliary processor may be powered (instead of a relatively high-power processor) or just one core of a multi-core processor. Data are written to the apparatus and can be recovered when main power is reconnected. Or, the apparatus may be detached and attached to a different device for data recovery.
