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.
