用四隻 peak transfer rate : 70MB/s ge HDD
假設行 RAID 0 = 4x70MB/s = 280MB/s peak
RAID 0+1 = 140MB/s peak

(((我知道冇可能真係幾個個 HDD 就乘幾多...but anyway...to make it easier to understand  ...

咁多問題, 最多逐條答

理論上raid 5都好快, 但係個XOR processor做唔做到咁快係1個問題...

咁即係最好 = RAID 0+1?

Raid 0+1個可用空間少嘛......
同埋無記錯, random read raid 5都幾好...
