The Flexi-Drive XC+ is a variable USB stick and card reader combination device and has now an even more practical design and a faster data transfer rate. The Flexi-Drive XC+ functions simultaneously as a card reader and as a USB stick. The two-in-one data medium reads and writes in Secure Digital and Multi Media Card formats as well as miniSD, microSD, MMCmicro, and MMCmobile formats with the use of an additional adapter. When connected to the PC as a card reader, the Flexi-Drive XC+ allows different cards to be inserted and used without having to reboot. By inserting a memory card, it is transformed into a USB stick with read and write access. The memory capacity can be varied arbitrarily according to which flash card is used.
