Memory Card Performance

Memory cards from SanDisk are known for their great performance. It has been to the preferred brand for ordinary camera users and most professional photographers.

On the technical side, Let us see how the SanDisk Ultra’s read and write speeds perform.

Write Speed

Memory write speed identifies the ability of an SD Card to store information from the camera at a given speed. For instance, a GoPro camera with a 4k 60 FPS video setting needs to transfer data to the SD Card at a rate of 7.5 MB per second. So, if you try recording 4k videos on an SD Card with write speeds lower than 7.5 MB per second you are going to encounter SD Card errors and the camera would crash.

You don’t want to be the person with a camera but misses every moment on an event because their SD Card keeps on failing. In this case, you should consider the memory card’s write speed before buying one.

The SanDisk Ultra has a write speed of up to 10 MB per second which is a bit slow. But, considering the price you can’t complain more.

Read Speed

After using your camera to record videos and capture photos, you are probably going to transfer those files to your computer. This is where memory read speeds are important. Read speeds identify the file transfer speed that an SD Card can handle while copying files to a computer or another storage device.

Large file transfer can take some time especially if you are about to transfer files with sizes of 20 GB or more. You would find your self staring on the computer for hours just waiting for the file transfer to finish.

SanDisk Ultra has a read speed of up to 80 MB per second which is decent considering its price. This is also the reason why SanDisk memory cards are awesome. They offer all-around performance on all their cards at a decent price. Some brands can be cheaper compared to SanDisk models but when you take a  look at the technical specifications, those cards would often have slow read speeds.
