Why do you want to format your M.2 SSD? For example, if you're planning to sell or give it away, you'll want to format it first to erase all of your data from the drive. You should also format your M.2 SSD if it needs to be fixed - this can sometimes fix performance issues. Finally, if upgrading the firmware on your M.2 SSD, you'll need to format it first. 

In summary, there are several reasons why you might need to format an M.2 SSD: 

- To choose a file system (NTFS or FAT32) 

- To make the drive compatible with a specific operating system 

- To erase personal data before selling or giving away the drive 

- To fix performance issues 

- To upgrade the firmware

🎯Which format to choose?

When you format an M.2 SSD, you choose a file system format that tells the computer how to store and organize files on the drive. The most common file systems are NTFS and FAT32. If you format your drive with NTFS, you'll be able to store and access files larger than 4 GB. However, NTFS is not compatible with all operating systems. If you format your drive with FAT32, it will be compatible with all operating systems, but you'll only be able to store files up to 4 GB. It would help if you formatted your M.2 SSD using the file system compatible with the operating system you plan to use.
