Win 7 system using SSD solid state drive data

  

On SSD, Windows 7 will automatically disable the disk defragmentation function, due to the excellent random read /write performance of SSD, similar to the function of disk defragmentation is not much Acted. Vista will perform automatic defragmentation. This is not only an unnecessary feature for SSDs, but, even worse, it can make SSD wear faster.

The Trim command can dominate a block of SSD and is no longer used. The SSD takes its space back into the next "loss-loss" operation. The Trim engine is specifically supported in Windows 7, and the utilization of each storage unit in the SSD can be detected and balanced.

Disk defragmentation is disabled in Windows 7 and is not required when using SSD drivers. At the same time, Superfetch and ReadyBoost functions are disabled. It is mainly to improve the performance of traditional hard disks in random reads and avoid serious bottlenecks. Perhaps the most important thing is that it supports Trim technology, which can greatly improve the performance of writing. The driver uses Intel's latest 34nm technology to improve the write performance of the previous generation, and reduce the delay by 25%, largely optimized for SSD.

Superfetch, bootprefetching, application launch prefetching, readyboost and ReadDriv are turned off when SSD is used with WIN7.

superfetch/prefetch: In win7 and vista, superfetch is used to find and copy the most frequently used program content into system memory to reduce read time. Superfetch is based on similar prefetch features in winxp. Intel's ssd does not need to use superfetch/prefetch. In order to achieve the best performance (note the word optimal performance), it should be closed.

The above information comes from the network, use SSD in WINDOWS 7, please don't worry too much, as long as your WIN7 is newly installed, the system will automatically optimize.

However, when the SSD is used with a traditional mechanical hard disk (non-USB interface, as a second hard disk), it is not tested whether it is optimized at the same time.
