This means that the data can only be transmitted in one direction at a time.<br \/>\nHowever, the USB 3.x standard knows the transfer of data in both directions. 3.x also offers a significant advantage in terms of speed. Those who take a closer look at USB 2.0 vs. 3.x,<br \/>\nwill notice that the transfer speed of the technically more modern USB 3.x is ten times higher than that of USB 2.0.<\/p>\n<p><strong>USB 2.0:<\/strong><\/p>\n<p>Devices with 2.0 can be connected to a USB 3.x port and increase the transfer speed at least slightly.<\/p>\n<p>The USB 2.0 specification was introduced in 2000 and is now the most widely used in modern computer systems.<br \/>\nThe transfer rate is in the range of 3~10 MB\/s for write speed and 10~25 MB\/s for read speed.<\/p>\n<p><strong>USB 3.x:<\/strong><\/p>\n<p>Devices with USB 3.x also work on a USB 2.0 port, but the advantages of USB 3.x cannot be used here.<\/p>\n<p>If the USB port inside is blue, it is a USB 3.x port. there are two wires for the signal and the power line as well as two further signal wire pairs and one<br \/>\nAdditional ground connection. Cable length max. 3 meters.<br \/>\nThere is often a small mark next to the connectors. The designation &#8220;SS&#8221; (Superspeed) or &#8220;3.x&#8221; indicates a USB 3.x port.<br \/>\nOpen the Device Manager, you will find all USB ports under the category &#8220;USB controllers&#8221;. If you see the term &#8220;USB 3.x&#8221; here, such a port is definitely present.<\/p>\n<p>The transfer rate is in the range of 10~45 MB\/s for write speed and 60~150 MB\/s for read speed.<\/p>\n<p><strong>USB 2.0:<\/strong><br \/>\nSequential write speed in the range of 3~10 MB\/s<br \/>\nSequential read speed in the range of 10~25 MB\/s<\/p>\n<p><strong>USB 3.x:<\/strong><br \/>\nSequential write speed in the range of 10~45 MB\/s<br \/>\nSequential read speed in the range of 60~150 MB\/s<\/p>\n<p>These read and write speeds are a guideline.<\/p>\n<\/div><\/section>\n<section class=\"av_textblock_section \"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock  '   itemprop=\"text\" ><input type=\"button\" value=\"Back\" class=\"alg_back_button_input \" style=\"\" onclick=\"window.history.back()\" \/>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-26731","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/pages\/26731","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/comments?post=26731"}],"version-history":[{"count":12,"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/pages\/26731\/revisions"}],"predecessor-version":[{"id":159613,"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/pages\/26731\/revisions\/159613"}],"wp:attachment":[{"href":"https:\/\/hikitec.de\/en\/wp-json\/wp\/v2\/media?parent=26731"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
