전체 문서는 17쪽이며, 그 중 관심가는 몇 가지를 해석합니다.


수퍼페치.. 윈도우 파일 사용 패턴을 분석해 메모리에 읽어들일 데이터를 최적화

레디부트.. 윈도우 부팅할 때 디스크에서 읽는 파일들 위치 정보 등을 미리 읽어 저장. 다음 부팅에 사용.

레디부스트.. usb메모리 등을 윈도 성능향상용 보조메모리로 사용

레디드라이브.. 하이브리드 하드디스크 지원



레디부스트


    To monitor the effectiveness of ReadyBoost, use the Windows Performance Monitor (PerfMon) tool that is included with Windows. Monitor the ReadyBoostCache performance counters. Bytes Cached is the amount of data stored in the cache. More bytes in the cache improve the chances for a higher hit-rate. However, more data cached does not guarantee that the cache is effective. The effectiveness of the cache is measured by the hit-rate, which you can obtain from the counters Cache Read Bytes/sec and Total Read Bytes/sec.


    To determine the WinSAT score of a device, run the following command from an elevated command prompt:

    WinSat disk –read –ran –ransize 4096 –drive E
    
    The above command displays the WinSAT score for drive 1E.



If the system drive is a fast SSD, SuperFetch turns off the ReadyBoot feature.
