[心得] U3碟測試:Sandisk Extreme USB 3.0
今天要測的是Sandisk 剛出的Extreme USB 3.0 Flash drive 64GB
照大陸拆解看來是Fujitsu的USB 3.0 to sata bridge配上sandisk自家ssd控制器.
照慣例沒開箱..直接上機測試.

也照慣例4K QD32又測到當機了...OTL
其他成績算很不錯, 循序讀取更是當今最速之一.

這個就很屌了...測到破表去了..XD
不過小檔案也跟之前的測試類似, 4k在intel的usb 3.0上略輸nec舊款.
但是循序非常強大...230/200的暴力性能.
應該是當今最速(沒有之一)..
性能非常強悍, 不過請記住這是64GB的速度, 32/16的版本速度都有打折.
dongle本身質感普普, 但雖然是常見的伸縮設計, 這隻的伸縮使用起來感覺
相當穩固, 應該會比一般兩光伸縮設計更耐用.以上~
