标题簇和簇的大小——Clusters And Clusters Sizes

　　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。
