Many photographers are interested in the question of how many pictures can 32GB hold. Compact and standard DSLR cameras commonly produce JPEG images. Further, you will see a table that contains approximate calculations so that you can imagine the possible number of pictures on your memory card.
This chart includes information on the approximate number of images on the SD card. All calculations were given for images shot in uncompressed RAW format.
The first chart shows the number of images that a memory card of different sizes can hold. So if you need to know how many pics does 16GB hold, look down.

The most reliable manufactures are SanDisk, Lexar, and Sony.
Typically, it can last 10 to 15 years. If you keep the chip package in a very dry environment, you can use it even longer.
As a rule, modern SD cards have data management in the controller chip. Thanks to this, you may not worry about data loss from the memory card as long as the chip is powered or it is not worn out.
There are three main types of SD cards available in the market: SD (Secure Digital), SDHC (Secure Digital High Capacity), and SDXC (Secure Digital eXtended Capacity). These types differ in terms of their storage capacity, with SD cards having a maximum capacity of 2GB, SDHC cards ranging from 4GB to 32GB, and SDXC cards offering capacities starting from 64GB up to several terabytes.
The speed class rating of an SD card indicates its minimum sustained write speed, which is crucial for tasks like recording high-resolution video or capturing burst shots. Higher speed class ratings, such as Class 10, UHS-I, or UHS-II, generally offer faster data transfer rates and ensure smoother performance, particularly in devices that require quick data writing and reading capabilities.
To safely eject an SD card from a device and prevent data loss or corruption, it is important to follow these steps:
First, ensure that any ongoing read/write operations involving the SD card have been completed or terminated. Then, use the appropriate software or system feature to safely eject or unmount the SD card before physically removing it from the device to ensure all data has been properly saved and written.
