Don't buy USB keys or 2.0 hard drives anymore!!! Why ? First of all, you should know that the #USB 2.0 supports date from 2005 and ceased to be in production in 2008. These dying to give way to 3.0 and with evolution we are today at 3.1 you 3.2 How to differentiate them? You should know that, all USB media having a black color or rarely red or other color interface as for certain brands such as #Sandisk at the entrance, all around the opening of this one: generally correspond to 2.0 going down . As for the 3.0 and above the color of their male or female inlet port have a blue color. So Black = 2.0 and lower / Blue = 3.0 and higher (today we are at 3.0) Nb: these colors are standards regulated by OSI. This one is for those who buy new equipment in store in their packaging. All information about the data transfer speed will be written there. For those who buy their USB keys second hand, the first thing to know is that you have to • Check the color of the orifice • Test the transmission speed, approximately: 112 Mbit/s for 2.0 and nearly 5 Gbit/s. You see the difference between the 2 technologies. It's huge 😳 😎 • Then claim a guarantee even if it is a week. You never know😅 😅 😅 • And also note that the market value of a USB 2.0 support will always be lower than that in 3.0🤷🏽♂ Finally, you should know that: the transfer speed will only be respected when the input technologies (usb keys) and outputs (usb pc or laptop port) are identical and of the same generation. These technologies are evolving so quickly that we are now using USB type C models. Chao chao 😉 😎 😎 😎 #SONA!!!!! By the way if you need a USB key or an external hard drive.
