Because these blocks are contiguous on the disk, there's better read and write performance for them.
由于这些块在磁盘上是连续的，其读取和写入的性能就会更好。
In particular, if a bunch of new data is being appended to a single file, XFS can allocate a single, contiguous region on disk to store this data.
尤其是，如果要将一批新数据添加到单一文件，XFS可以在磁盘上分配一个单一、相邻区域来储存这些数据。
Partitions are containers that consist of contiguous sectors on the disk; partitions are defined by simple data structures.
分区是由磁盘上相邻扇区组成的容器，分区是由简单数据结构定义的。
The key to this optimization is that by delaying the allocation of physical blocks until they need to be written to the disk, more blocks are present to allocate and write in contiguous blocks.
这种优化的关键是延迟物理块的分配，直到需要在磁盘上写这些物理块时才对其进行分配并写到相邻的块。
When data are contiguous, the time used to access data on the disk is minimized and the database server can read data faster.
当数据连续时，用于访问磁盘上数据的时间最少，数据库服务器可以更快地读取数据。
Journaling is the process of logging changes to the file system through a journal (which is a dedicated circular log on a contiguous region of the disk).
日志记录就是通过日记(磁盘上相邻区域的专门循环记录)记录文件系统的变更的过程。
In a virtual storage system, a fixed-length block of contiguous virtual addresses copied as a unit from memory to disk and back during paging operations.
在虚拟存储系统中，一个固定长度的连续虚拟地址块，在分页操作过程中它作为一个单位在内存和磁盘之间来回复制。
Ext4 fixes this with a block allocator that allocates multiple blocks at a time, likely contiguous on disk.
ext4使用块分配器修复了这个问题，它能够在磁盘上一次分配多个块。
Because extents are allocated as needed, the extents of a segment may or may not be contiguous on disk.
由于段中区的分配是按需进行的，所以段中的区在磁盘上可能不是连续的。
Data is written to a hard disk drive using shingled writing principles, i. e., each data track is partially overwritten when an immediately contiguous data track is written.
使用重叠写入原理将数据写入硬盘驱动器中，也就是说，当紧邻的数据轨道被写入时，每个数据轨道被部分地覆写。
