How to Format an SD Card and Reveal Its True Potential

When it comes to formatting an SD card, there are several options available. In this article, we will explore three file systems: FAT32, exFAT, and NTFS. Each has its own set of advantages and disadvantages, which we will discuss in detail.

The Advantages of NTFS

One of the biggest advantages of using NTFS is that it overcomes the limitations of the FAT32 file system regarding maximum file size and partition size. Additionally, NTFS adds features like support for setting permissions and other useful tools for modern computers. However, its biggest downside is the lack of a journaling feature, which can make it difficult to recover from data corruption.

The Speed Comparison

To compare the speed of each file system, we used three different flash drives: the Kingston DataTraveler Elite G2, the Kingston DataTraveler microDuo 3C, and the IronKey D300. We formatted each drive using FAT32, exFAT, and NTFS, and then ran CrystalDiskMark to measure their speed.

The Results

Our results showed that exFAT was consistently faster than FAT32, while NTFS tended to be faster too, sometimes by a more significant margin. However, it's worth noting that not all measurements were consistent across all three file systems.

In conclusion, formatting an SD card can be a complex task, but by understanding the advantages and disadvantages of each file system, you can make an informed decision about which one to use. Whether you choose FAT32, exFAT, or NTFS, we hope this article has provided you with the information you need to reveal your SD card's true potential.
