昨天買了新手機(J7 2016),順便也買了記憶卡(Sony 64UY3A)
裝上去之後用程式(A1SDBench)去測,對結果有點疑問
Sony這張卡包裝上是寫90MB/s讀取
當然這是理想值,但是照理說實際結果不應該差太多
但是反覆測試的結果,讀取都一直在46附近徘徊 (寫入則是19左右)
想說會不會是卡有問題?所以拿了E8雙卡版來測試
同一張卡,裝在E8上的結果是:讀取80 寫入19
最後又把本來裝在E8上的記憶卡(廣穎64GU1)格式化,拿來測試
E8:讀取60 寫入17
J72016:讀取44 寫入16
想請問的是;不同手機,對記憶卡的讀取速度會影響到這麼大嗎?
有點怕是剛買的手機出問題 = ="
