時間Thu May 19 20:53:21 2011
平台:
GA-H67MA-UD2H-B3
Intel 6系列內建USB 2.0
Renesas USB 3.0 Host controller
USB 2.0:
因為懶得找地方插, 直接接在外部的Belkin hub上,速度似乎略低

評: 讀取小勝上面的TDK, 4K寫入QD32就整個弱了.
USB 3.0:
接在銀欣垃圾桶拉出來的port上, Renesas Host controller on GA-H67MA-UD2H-B3

評: 4K/512K寫入比usb 2.0的dongle還爛是啥鬼, 只有讀取能看而已...
那個個位數的4K寫入IOPS..只能科科了..

評: 性能平衡,比樓上那隻好很多.不過價格也遙遙領先就是了..=_=
