我想問記憶卡的 speed 倍速(x) 和 data transfer rate (mb/sec） 兩者是如果轉換 ?
如60x .. 即是幾多 mb/sec ?

Please correct if wrong,

1X = 150kb/s
.
.
.
.
60x = 9mb/s

have a nice shoot !

1x = 150 KB/s (Kilo-Byte per second)
1024KB = 1MB

60x = 60 x 150 KB/s = 9000 KB/s

9000 KB/s / 1024 = 8.789 MB/s (Mega-Byte per second)

Usually the reading speed is faster than the writing speed, some brands of memory card had written both of the reading and writing speed on the packing.

But some cheaper brands had only written the reading speed on the packing, and the customer found out the writing speed is very slow when using it.

奇實睇Memory Card指標唔一定係幾多X,

仲要留意張咭o既Process Rate!!!

即係指令寫入/讀取執行速度...

thx a lot ......

但可唔可以講多d俾我知咩係Process Rate ? 我完全未聽過 ~
同read & write speed 有咩分別 ?
