Intel RST與Win軟體raid相比的優勢 - 儲存設備

當時發文完後想了一想，還是決定買兩顆硬碟來做測試，如果真的沒有加速那再說
不過組電腦的時候遇到了一些問題…所以直到現在才實測
另外主機板拿的不是B360也不是B365，是Z390
只能說一切都是意外…

CPU：Intel i5-9600KF
硬碟：TOSHIBA DT01ACA200 2TB * 2
測試軟體：CrystalDiskMark 7.0.0g

嗯…看起來的確讀取有變快，代價就是寫入變慢一點點
加速的目的是達到了，不過我實際上不懂這些測試是在測甚麼的
還是把結果PO上來給大家參考～

之後會用Intel RST再作一次，不知道在這之前各位板友還覺得我要測什麼？
比如說CPU的使用率？

編輯：忘了提到檔案系統是NTFS。
