簇和簇的大小 Clusters And Clusters Sizes 蒋峻岭 1997-01-01   A cluster is the smallest amount of disk space that can be allocated within a FAT partition (or logical volume).The size of a cluster can range from 2K to 32K depending on the partition size.The larger the parti-tion,the larger the cluster size.   簇是一个FAT分区(或称逻辑卷)内所能分配的最小的磁盘空间,根据分区的容量,簇的大小可以从2K到32K。分区越大,簇就越大。   Since the operating system must allocate whole clusters,if the size of a file is not an even multiple of the cluster size there will be unused space within the last cluster.This space can not be used by another file and is,in effet,lost.If a partition  has a large number of files smaller than the cluster size,a significant percentage of  storage space can be lost.   由于操作系统必须整簇整簇地分配,因此,若某个文件的大小不是簇大小的整数倍,在最后一个簇中就会有未被使用的空间。该空间不能被另一个文件使用,实际上,被浪费了。如果某个分区存在许多比簇还小的文件,大量的磁盘空间就可能会被浪费。   If you expect to be storing a large number of small files,you may wish to consider dividing your hard drive into two  or more partitions. The smaller partitions  will have smaller cluster sizes.   如果预计要存储大量小文件,你可能会考虑将硬盘划分为两个或更多的分区,分区越小则簇也越小。
