Do you know the reason why the cost of SD card is more expensive than usb drive based on the same capacity ?

As a supplier in gift industry , have you been asked the same question ? Today ,let`s explain that more clearly.

We all know ,the key part of any storage device is wafer.

Usually, good quality of wafer is used for SSD firstly ,then SD,TF ,chipset for usb drive is the last.In other words,cut the core region to make SSD,then,TF, the edge of wafer plate is used for usb flash drive,why do they devide by that way ?

The answer is usage.

SSD plays an important role in computer , once there is something wrong with ssd,your PC stops work; the same way,if TF card inserted in your cellphone or SD card in your camera stops working ....besides,that is another proof why PC usually costs more comparing with cellphone or camera.

Hope above info would work out for you,
