SD speeds on your Oppo A9

These speeds are recorded in the same way as CD-ROM speeds, where 1 × equals 150 Kb / s. Standard SD cards go up to 6 × (900 Kb / s).

In addition, there are SD cards with a higher available data transfer, such as 600 × (almost 88 MB / s). Note that there is a difference in reading and writing speed, where the maximum write speed will always be slightly lower than the maximum read speed. Some cameras, especially with burst shots or (Full-) HD video cameras, need high speed cards to make it run smoothly.

These classes represent the minimum guaranteed data transfer rate that a card can achieve.

This means that when read and write operations are performed on the memory card at the same time, the manufacturer gives the guarantee that this minimum speed is maintained.

A Class 2 memory card can guarantee a speed of 2 megabytes per second, while a Class 4 memory card guarantees a transfer of at least 4 megabytes per second.

This can cause confusion when buyers of memory cards only read the specifications for the maximum speed of a memory card (80 ×, 120 × or 300 × …, UDMA, Ultra II, Extreme IV or even 45 MB / s), and not the specifications of the minimum speed displayed for your Oppo A9.

Cards With Sound

UHS could be available on your Oppo A9

Ultra High Speed is the new definition for even faster SD cards. What is new is that, in addition to a minimum speed (class), a maximum speed (roman sign) is also indicated.

In addition, UHS-II must always be faster than the maximum of UHS-I. For a classification UHS-I, the speed must be at least 50 MB / s and at most 104 MB / s., A classification UHS-II must have a minimum speed of 156 MB / s and a maximum of 312 MB / s.

A UHS card therefore always has two indications, a number within a U (the class) and a Roman number.
