Capacity of folder on extreme portable ssd 500GB

Hello, I have bought a Sandisk Extreme Portable SSD 500GB recently and found an issue. I copied a 28,05GB folder on it but when I checked Disk Utility on my Mac it showed that my portable ssd was used 54,66GB. Can someone help me with this? (Sorry for bad English, I’m a Vietnamese)
