Data allocation method and device capable of rapid allocation and better exploitation of storage space

Abstract

The present invention discloses a data allocation method. An embodiment of this method comprises: preparing a storage space; allocating some of the storage space as a first current page, a second current page, a first next page, and a second next page; comparing a first data amount with a first spare space of the first current page, and comparing a second data amount with a second spare space of the second current page; storing first data in the first current page if the first spare space is enough for the first data amount, or else storing the first data in the first next page; and storing second data in the second current page if the second spare space is enough for the second data amount, or else storing the second data in the second next page, wherein the storage processes for the first and second data are executed simultaneously.
