当从硬盘驱动器读写表和索引数据时，DB 2使用缓冲池来缓存它们。
DB2 USES buffer pools to cache the table and index data as they are being read or written to the hard disk drive.
这指的是驱动器上可用的缓存数，以及用于读写数据的算法集。
This is the amount of cache available on the drive, as well as the set of algorithms that are used to read and write data.
JungleDisk的备份功能很强，还可以与其它读写网络驱动器的应用程序同时协作。
Jungle Disk is great at backup, but you can also use it with any application you'd like that can write to a network drive.
索引不要与存储库放在同一个驱动器上，也不要与其他频繁的读写活动（如日志记录）在同一驱动器上。
Your indexes should not be on the same drive as the repository, or other high read or write activities, such as logging.
这成功提高了文件的读写速度，特别是在有经常性改动的驱动器下，比如你用来暂存或交换文件的驱动器，或者，对数据文件有频繁修改的驱动器。
This enables faster file reads and writes, especially on drives with frequent changes, such as the drive you use for temporary or swap files or drives with frequent modifications to data files.
当你要计算机读写软盘时，你要把它放入软盘驱动器（亦称软驱）中。
When you want the computer to read information from a floppy disk or write information on it, you insert the disk in your floppy disk drive.
当你要计算机读写软盘时，你要把它放入软盘驱动器（亦称软驱）中。
