This is simple, and that is for assurance. The system has a minimum of 5 drives on the computer. There is an SD Card reader, and a microSD Card reader. The micro-SD Card reader might be an option for holding files you want to remain, but may not use them everyday. You could also use this drive as a downloads drive, so all of the files you download from the network will come to this drive. The options up to the owner. What might seem like a gimmick is the inclusion of a 64GB? card. 64GB doesn’t store a lot these days, and the only thing smaller is free storage provide by Senitrus Computers. If you are on a tight budget, then the 64GB micro-SD card will be beneficial, and will likely use it until the upgrade. You will have options to upgrade your microSD card to a maximum of 2TB?. This will allow you to not have to worry about having cards that you would never use.
