I managed to transfer about 3 gigabytes from the Samsung Galaxy Note20 Ultra's internal storage in less than 10 seconds. I then transferred about 30GB of data from the SanDisk 512GB Extreme microSDXC that was in my Samsung Note20 in about 6 minutes. The case heats up during data transfer. Transfer speed is high for most apps to quickly backup your smartphone in minutes and play videos stored on external drive for watching on the go without overloading your phone's storage. The case is very small and made of plastic. It has no indicator lights for reading or writing. There is a USB-C port that can be directly connected to Windows OS, Apple OS or Android. After connecting to my Samsung Note20, it formats the drive to make it ready to use. Overall, this is amazing value for money. Sterling W
