[理工] 計組 MTTF最低的RAID
最近唸到io跟周邊
有兩個問題
一個是有一題她問
describe a technigue in disk arrays that may result in very low MTTR.
為什麼是RAID5不是RAID1直接一份copy的用不是最快嗎
然後還有一個小問題書上範例答案看不太懂，它是寫
MTTR => 0 is not a realistic situation since replacing file systems and other
data can take significant time
我不太懂replace是什麼動作會嚴重花費時間
謝謝各位><
