![]() 平常買記憶卡 都看品牌。很少注意他的標示如 microSDXC UHS-I...A1 Class10 (U3) 之類的。
MicroSDXC UHS-II 這類的價格比較高 高很多... microSDXC UHS-I(V30)(A2) 特別 不一樣人家是A1 他就寫A2 有比較快嗎?!答案是很多人測試 都沒有。 只有MicroSDXC UHS-II U3 V90 背面晶片金手指雙排 才有比較快。 而且要找到大容量 幾乎很少見。我也沒看過手機,有支援到MicroSDXC UHS-II Application Performance Class A1 A2 怎麼測試差異。 https://www.sdcard.org/consumers/ab...martphone-apps/ 協會說的...有講跟沒講 好像就不是很重要。而高級一點的錄影機GoPro相機配合使用的SD卡...

協會標示應是低標吧,
但近年經驗,SD(uSD)讀寫速度標示常是"笑果". 我是參考下列網站實測再決定, 即使同品牌,型號前後期產品也不一樣. https://www.cameramemoryspeed.com/reviews/sd-cards/ |

印象市售的讀卡機幾乎沒有支援A2的,所以測不出來甚至低於A1。。。A1/A2影響就是4K小檔隨機讀寫。UHS-II這方面是很差的,因為連A1都沒有,大多1-2MB/s。
