You'll even examine some file system attributes, such as sequential and random access, which can affect performance.
甚至还将研究一些可能影响性能的文件系统属性，比如顺序访问和随机访问。
By looking at the read and write sequence counts in detail, you can further determine if the access is sequential or random.
通过仔细地观察读写序列计数，可以进一步确定访问是顺序的还是随机的。
As a result, the disk access time is much longer when reading data in random order than when reading in sequential order.
因此，与按顺序读取相比，按随机顺序读取数据时的磁盘访问时间要长得多。
Sequential access, as exhibited by data warehouse activities, does not produce as great a performance improvement with SSDs as does random access.
在数据仓库活动所用到的顺序存取中，SSD的性能提升没有随机访问那么大。
Batch and query applications typically do a lot of sequential processing, while data access for OLTP tends to be more random in nature.
批处理和查询应用程序通常要进行大量的顺序处理，而用于OLTP的数据访问往往更具有随机性。
For example, with typical page sizes of 8 KB or 16 KB, in-page processing is inherently sequential and less CPU-efficient than random data access.
例如，对于典型的8KB或16 KB的页面，页内处理天性是连续的，CPU效率低于随机数据访问。
Tape persisted as the storage medium of choice, even though it suffered from poor performance and the need for sequential, not random, access to stored data.
即便磁带的性能不佳、只能顺序而不是随机存取储存的数据，但磁带作为存储介质一直未变。
The time it took was irrespective to their address sequence. Magnetic disc is a form of storage which provides the convenience of random access. See Sequential access.
所需的时间与数据所在的地址次序无关。磁碟便是一种提供即时存取方便的贮记器。参阅顺序存取。
Since it is not using high speed spinning disks as storage media like traditional hard disks, SSD obtains much higher sequential and random access speed than traditional hard disks.
由于它不是以高速旋转的磁盘作为存储介质，数据读写时不需要寻道时间，因此它有着传统硬盘不可比拟的顺序和随机存储速度。
It allows you to use low-level routines, high-level ISAM routines, or the ODBC layer for high-speed random or sequential data access.
它允许你使用低水平程序，高水平ISAM程序，或者用于高速随机或者连续数据访问的ODBC层。
It allows you to use low-level routines, high-level ISAM routines, or the ODBC layer for high-speed random or sequential data access.
它允许你使用低水平程序，高水平ISAM程序，或者用于高速随机或者连续数据访问的ODBC层。
