由此可见,对于物理扇区大小与逻辑扇区大小不一致的磁盘,分区4K对齐才能充分发挥磁盘的读写性能。而不对齐就会造成磁盘读写性能的下降

对齐到多少个扇区才正确

知道了“扇区大小”和“物理扇区大小”,用“物理扇区大小”除以“扇区大小”就能得到每个物理扇区所包含的逻辑扇区个数。这个数值就是我们要对齐的扇区个数的最小值。只要将分区起始位置对齐到这个数值的整数倍就可以了。举个例子,比如物理扇区大小是4096字节,逻辑扇区大小是512字节,那么4096除以512,等于8。我们只要将分区起始位置对齐到8的整数倍扇区就能满足分区对齐的要求。比如对齐到8、16、24、32、... 1024、2048等等。只要这个起始扇区号能够被8整除就都可以。并不是这个除数数值越大越好。Windows系统默认对齐的扇区数是2048。这个数值基本上能满足几乎所有磁盘的4K对齐要求了。


为什么大家都说4K对齐

习惯而已。因为开始出现物理扇区的概念时,多数磁盘的物理扇区大小都是4096即4K字节,习惯了就俗称4K对齐了。实际划分分区时还是要检测一下物理扇区大小,因为有些磁盘的物理扇区可能包含4个、8个、16个或者更多个逻辑扇区(总是2的n次方)。知道物理扇区大小后,再按照刚才说的计算方法,以物理扇区包含的逻辑扇区个数为基准,对齐到实际的物理扇区大小才是正确的八度棋牌信誉怎么样。如果物理扇区大小是8192字节,那就要按照8192字节来对齐,严格来讲,这就不能叫4K对齐了。


划分分区时如何具体操作分区对齐

软件在“扇区数目”下拉框中列出了很多的选项,从中选择任意一个大于物理扇区大小的扇区数都是可以的,都能满足对齐要求八度棋牌信誉怎么样。软件列出那么多的扇区数选项只是增加了选择的自由度,并不是数值越大越好。使用过大的数值可能会造成磁盘空间的浪费。软件默认的设置已经能够满足几乎所有磁盘的 4K对齐要求。

除了“建立新分区”对话框,DiskGenius软件还有一个“快速分区”功能,其中也有相同的对齐设置。如下图所示:

如何检测是否对齐

作为一款强大的分区管理软件,DiskGenius同样提供了分区4K对齐检测的功能。你可以用它检测一下自己硬盘的分区是否对齐了。使用方法很简单,打开软件后,首先在软件左侧选中要检测的磁盘,然后选择“工具”菜单中的“分区4KB扇区对齐检测”,软件立即显示检测结果,如下图所示:

1、用“备份分区”的功能将未对齐的分区备份到镜像文件中。

2、shanchuweiduiqidefenqu,ranhouzhongxinjianli,jianlishixuanze4kduiqi。

3、用“从镜像文件还原分区”的功能通过第一步备份的镜像文件还原分区数据。
