#4	The device card is used for transfer between PCIE and PCIE
#5	But even with USB 30 the theoretical bandwidth is only 5 Gbps 625 MBs and the loss is only 150 MBs in four minutes and even the single channel bandwidth of PCIE 1x is 250 MB s so this can give you the most slots but not enough bandwidth onl
