X58平台+LSI9260-4I+Vertex3 240gb 4kb效能未如理想...請c兄幫助(有圖)
小弟平台,intel 980x,asus r3e,6gb ram,

岩岩第1次買番來使用Marvell9123_Controller sata3 / 6gbs 來行隻vertex3 240gb表現如下

之後覺得有d 浪費了隻vertex3 240gb,之後決定重本買多張lsi raid card

點知出來第1次既效果係....


之後覺得4kb 都係強差人意...之後也證實了raid 卡係行緊pci-ex16 插槽,之後再係raid card setting 度set 左個類似1mb cahce定係stike cahce之後..效能就變左咁4kb都係偏差....本人都raid card入面 enable achi \ncq 之類function,問題都係咁...由於改動一次setting..ssd內既data都會完全清除,所以希望有ching能幫忙解答到小弟既問題or 研究一下

這個是最新測試出來的數據..
