By allowing fast access to frequently used data, software can run much faster than if it had accessed the data from the main memory.

由于允许对频繁使用的数据进行快速存取，软件运行要比从主存储器中存取数据快得多。

Compression is especially valuable for read-intensive applications, on systems with enough RAM to keep frequently used data in memory.

压缩对于以读为主的应用程序更有价值，因为这样能够使得系统有足够的内存把频繁使用的数据都保持在内存里。

It allocates the most frequently used variables into the most readily accessible RAM and puts less frequently used data into XDATA RAM.

它将最为常用的变量分配到了最容易读取的RAM中，并将使用频率较低的数据分配到XDATA RAM。

The flash memory in the Fusion Drive moves data and applications frequently accessed by the user to the flash memory and move less frequently used data to the hard disk drive as the flash memory becomes full.

FORBES: Will A Fusion Drive Approach Become Widespread in Computers?

The company has introduced products for this industry before but it appears that the time is right for these products as well as hybrid HDDs (HDDs that contain some cache flash memory for frequently used data) to become wide-spread in computer architectures.

FORBES: New Technology and Investment Opportunities at the 2011 Intel Developers Forum

Using a combination of HDD and flash memory in either a hybrid HDD or a dual storage notebook computer, where frequently used data (and possibly the operating system and application software) is kept in the flash memory, while the bulk of user content is kept on the HDD, has been shown to provide about 80% of the performance improvements of a pure SSD-based computer.
