Note: USB flash drive speed is influenced by a variety of factors, such as,

• The interface type of your device should also be USB 3.2 to achieve the maximum speed of 550MB/s. If it's USB 3.0 or USB 2.0, the speed will be slower.
• The cache size of the host device: If the file being transferred is larger than the computer's (or phone's) cache, when the cache is full, the speed will slow down.
• The size of the files being transferred: The speed of transferring complete large files will be faster than that of scattered small files.
• Other specifications of the host device you’re using.

So the actual transmission speed will not always remain at the maximum speed.
