SD cards are a familiar storage device for digital cameras, and I buy the ones with good specs at the time for around 2,000 yen. SD cards have a speed to write and read data, and the faster this speed is, the faster the camera will be able to record the photo if it was taken, or display the contents on the monitor faster if you want to see them. In particular, the faster the writing is done, the less time the camera has to wait after pressing the shutter release button because it means it is ready for the next shot. This increases the response time of the shot, so you don’t miss the next shot that comes along after you press the shutter (not exactly the same thing as high-speed continuous shooting). However, speed is proportional to price, so it is important to balance speed and price with your wallet. It is also important not to make the mistake of choosing an expensive SD card just because it is fast, but that does not mean it will be dramatically faster. Because of this, I try to look for SD cards around 2,000 yen, and I decided it was about time for a new SD card, so I went to Akihabara to look for one.
