SD cards are mostly used for camera devices, they are small in size but have a sizeable storage configuration that allows many large RAW images captured by the camera to be stored on them. An SD card will still eventually end up connected to the desktop computer to save, process, or backup images on it.
SD cards have fairly fast transfer speeds and some are faster than others. Speed really depends on the type and manufacturer of the card you buy.
SD card speed test
An SD card is a storage device that is connected to a computer via a card reader. This is usually an internal device although external devices can also be connected to it.
Since the SD card is not connected to the computer via a USB port or internal port, the transfer speed will not be the same as what you get when reading/writing files to a device connected to that port.
To test SD card speed, you need an app. We recommend using the AJA System Test. Here’s how to test SD card speed in Windows 10 using AJA System Test:
1. Download AJA System Test from hereand install on your PC/laptop.
2. Run the application.
3. From the column on the left, click on Target Disk.
4.Select discie SD card.
5. Click Start.
6. Let the test read and write run to completion.
The speed of each will tell you how fast the data can be read and written to the SD card. AJA System Test clearly displays current test results as well as configuration information in an easy-to-use graphical interface.
The pull-down menu lets you quickly select the type of test to run, which drive to evaluate, the video size and frame rate, as well as the overall file size and any connected video devices.
SD card speed is slow
SD card speed may be much lower than advertised. This has to do with several things like the speed of the SD card reader you are using, the file system on which the SD card is formatted, and the size of the file being transferred.
In general, you can get a fast card reader for better/faster transfer speed. This may, or may not work. As for file systems, all file systems tend to have the same transfer speed, but if you are transferring large amounts of small files, SD card is better to use NTFS.
You may often find that the SD card gives slower speed on the computer. The speeds are generally advertised for the type of device the SD card uses, namely the camera. With cameras, you will again notice some differences in speed because not all cameras are the same. Older cameras will most likely not be able to take advantage of an SD card that supports faster transfer speeds.
