How to check your SD card’s health?

Sandisk does not have any tools to check the SD card’s health. However, you can use tools like H2testw which allows you to verify the actual data writing and reading capacity of the storage device. It works with hard disks, network drives, SD cards, and USB sticks.

Tips for using an SD card

If you have intensive demands, it is advisable to select a high-endurance SD card. Instead of randomly choosing an SD card and being concerned about its capacity or read-write speed, it is recommended to prioritise an SD card with high endurance from the beginning, such as the Sandisk brand.

Format the SD card

Before using any SD card you should always format it first. It is advisable to format all external storage media before usage. this is important because formatting not only removes any testing data left by manufacturers on the car but also ensures that the SD has a correct and compatible file system.

To prolong the lifespan of your Dash Cam SD card, it is recommended to format it on a monthly basis. The wear-leveling efficiency of the SD card in Dash Cams is generally poor. Some blocks may become overused while others remain underutilized when only a few pieces of data are stored. By performing a complete erase of the entire memory card through formatting, you provide an opportunity for all those idle blocks to be utilized once again.
