近日發薪,在網家逛MicroSD卡已久
本人雖是鐵金信仰,但放眼望去,SanDisk似乎產品廣又猛
於是在各種比較下,決定買Extreme Pro A2那張黑底金字的小卡
收到貨後第一件事就是跑分
測試平台1
筆電內建PCIe讀卡機 (L牌 IP320S-13IKB),高效能模式
CrystalDiskMark 6.0.1
測試平台2
Samsung Galaxy S8 SM-G950FD
Disk Speed / Performence Test

並非所有裝置都支援micorSDXC記憶卡格式,若需詳情請洽詢您的裝置製造商。
1.讀取速度高達170MB/s,寫入速度高達90MB/s。根據內部測試;視主機裝置、介面、
使用情況和其他因素而定。
7.4000讀取IOPS,2000寫入IOPS。結果可能會因為主機裝置、應用程式類型和其他因素
而有所不同。

R77/W67 MB/s
然後4K Q32T1
R: 8.177M / 4K = 2093.31 IOPS
W: 2.654M / 4K = 679.42 IOPS
Disk Speed / Performence Test 測試
https://i.imgur.com/uGhxpzv.png
R74/W57 MB/s
手機讀卡機效能約打九折
Windows Explorer 檔案傳輸

https://i.imgur.com/XelaAT4.png
R81/W70.6 MB/s
小結:
不論是連續讀寫,或是隨機存取,大致符合A1等級,然而皆與標示落差甚大
直到上網Google這張卡的身家,原來要發揮這張卡的實力,得要使用SanDisk自家讀卡機
而且就在我每天逛的儲存版......
本人臆測應該是自家讀卡機能對主控超頻
使得4K與連續讀取翻倍,真是黑科技
那標示行動裝置的A2意義就不明了
這一點跟9900K的Up to 5GHz,TDP 95W有87%像XD
直到退貨前,看了下外包裝,似乎有鬼
背面的標示只有A1,右上角多一個2,不確定是否是相同意思
https://i.imgur.com/ge43gx6.png
友人曾說是沿用舊包裝,但正面標示明確的速度反駁這點
https://i.imgur.com/mnjmn97.png
於是趁網家12/12特價
我又買了另一張記憶卡
https://i.imgur.com/28Amvtq.png
剩下轉接卡,小卡拿去插了
CrystalDiskMark
https://i.imgur.com/qF778uQ.png
讀取快了一點,但Random Access慢了一點 1874 / 626 IOPS
價錢1499對上799,終身保vs十年保
說實在10年前的記憶卡,我現在連灰塵都懶得擦
完
金金表示流淚
我是大韓台北人
