I remember my first flash drive was 256MB in volume, and it was just awesome. Five years have passed and now please, DataTraveler 300 with a capacity of 256GB is a record today. Moreover, the previous record holder of 128GB, appeared only a few months ago. If you believe the approval of the company Kingston, data can be written at a speed of 10 megabytes per second, and read no faster than 20 megabytes. The superflash is slightly larger than the usual 70.68 x 22.37 x 16.45mm and is very expensive, almost 1000 dollars.
