Bem uma delas é quanto a velocidade: 10x mais rápido que o anterior. A versão atual possui uma velocidade máxima de 480 megabits por segundo o que nos daria em média 60mb/s de taxa de tranferência, na maioria das vezes sub-utilizado, pois a maioria dos dispositivos operam a 30mb/s. Já a nova versão poderá atingir incríveis 4.8 gigabits por segundo.Com uma taxa de trasnferência de até 395 Megabytes por segundo, o padrão USB 3.0 pode se tornar ideal para dispositivos de armazenamento, mp3 player, transferência de arquivos, entre outros.<!--[if gte mso 9]>     Normal   0         21         false   false   false      PT-BR   X-NONE   X-NONE                                                     MicrosoftInternetExplorer4                                                   <![endif]--><!--[if gte mso 9]>                                                                                                                                                                                                                                                                                                                                                                                                                                <![endif]--> <!--  /* Font Definitions */  @font-face 	{font-family:"Cambria Math"; 	panose-1:2 4 5 3 5 4 6 3 2 4; 	mso-font-charset:1; 	mso-generic-font-family:roman; 	mso-font-format:other; 	mso-font-pitch:variable; 	mso-font-signature:0 0 0 0 0 0;} @font-face 	{font-family:Calibri; 	panose-1:2 15 5 2 2 2 4 3 2 4; 	mso-font-charset:0; 	mso-generic-font-family:swiss; 	mso-font-pitch:variable; 	mso-font-signature:-1610611985 1073750139 0 0 159 0;}  /* Style Definitions */  p.MsoNormal, li.MsoNormal, div.MsoNormal 	{mso-style-unhide:no; 	mso-style-qformat:yes; 	mso-style-parent:""; 	margin-top:0cm; 	margin-right:0cm; 	margin-bottom:10.0pt; 	margin-left:0cm; 	line-height:115%; 	mso-pagination:widow-orphan; 	font-size:11.0pt; 	font-family:"Calibri","sans-serif"; 	mso-ascii-font-family:Calibri; 	mso-ascii-theme-font:minor-latin; 	mso-fareast-font-family:Calibri; 	mso-fareast-theme-font:minor-latin; 	mso-hansi-font-family:Calibri; 	mso-hansi-theme-font:minor-latin; 	mso-bidi-font-family:"Times New Roman"; 	mso-bidi-theme-font:minor-bidi; 	mso-fareast-language:EN-US;} p.MsoNoSpacing, li.MsoNoSpacing, div.MsoNoSpacing 	{mso-style-priority:1; 	mso-style-unhide:no; 	mso-style-qformat:yes; 	mso-style-parent:""; 	margin:0cm; 	margin-bottom:.0001pt; 	mso-pagination:widow-orphan; 	font-size:11.0pt; 	font-family:"Calibri","sans-serif"; 	mso-ascii-font-family:Calibri; 	mso-ascii-theme-font:minor-latin; 	mso-fareast-font-family:Calibri; 	mso-fareast-theme-font:minor-latin; 	mso-hansi-font-family:Calibri; 	mso-hansi-theme-font:minor-latin; 	mso-bidi-font-family:"Times New Roman"; 	mso-bidi-theme-font:minor-bidi; 	mso-fareast-language:EN-US;} .MsoChpDefault 	{mso-style-type:export-only; 	mso-default-props:yes; 	mso-ascii-font-family:Calibri; 	mso-ascii-theme-font:minor-latin; 	mso-fareast-font-family:Calibri; 	mso-fareast-theme-font:minor-latin; 	mso-hansi-font-family:Calibri; 	mso-hansi-theme-font:minor-latin; 	mso-bidi-font-family:"Times New Roman"; 	mso-bidi-theme-font:minor-bidi; 	mso-fareast-language:EN-US;} .MsoPapDefault 	{mso-style-type:export-only; 	margin-bottom:10.0pt; 	line-height:115%;} @page Section1 	{size:612.0pt 792.0pt; 	margin:70.85pt 3.0cm 70.85pt 3.0cm; 	mso-header-margin:36.0pt; 	mso-footer-margin:36.0pt; 	mso-paper-source:0;} div.Section1 	{page:Section1;} --> <!--[if gte mso 10]>   /* Style Definitions */  table.MsoNormalTable 	{mso-style-name:"Tabela normal"; 	mso-tstyle-rowband-size:0; 	mso-tstyle-colband-size:0; 	mso-style-noshow:yes; 	mso-style-priority:99; 	mso-style-qformat:yes; 	mso-style-parent:""; 	mso-padding-alt:0cm 5.4pt 0cm 5.4pt; 	mso-para-margin-top:0cm; 	mso-para-margin-right:0cm; 	mso-para-margin-bottom:10.0pt; 	mso-para-margin-left:0cm; 	line-height:115%; 	mso-pagination:widow-orphan; 	font-size:11.0pt; 	font-family:"Calibri","sans-serif"; 	mso-ascii-font-family:Calibri; 	mso-ascii-theme-font:minor-latin; 	mso-fareast-font-family:"Times New Roman"; 	mso-fareast-theme-font:minor-fareast; 	mso-hansi-font-family:Calibri; 	mso-hansi-theme-font:minor-latin;}  <![endif]-->  O USB 3.0 também vai manter a mesma arquitetura e a facilidade de uso características do USB 2.0. As melhorias viriam com otimizações relacionadas ao consumo de energia e à eficiência do protocolo. Tudo sem perder a compatibilidade com os dispositivos atuais.  A previsão do USB 3.0 Promoter Group, grupo responsável pelo desenvolvimento da nova especificação, formado por Intel, HP, Microsoft, NEC, NXP e Texas Instruments, é que o USB 3.0 chegue às ruas no primeiro semestre de 2008.    Fonte: [Info], www.guiadohardware.net<!--[if gte mso 9]>     Normal   0         21         false   false   false      PT-BR   X-NONE   X-NONE                                                     MicrosoftInternetExplorer4                                                   <![endif]--><!--[if gte mso 9]>                                                                                                                                                                                                                                                                                                                                                                                                                                <![endif]--> <!--  /* Font Definitions */  @font-face 	{font-family:"Cambria Math";

O USB 3.0 suporta transferência de dados à velocidade de até 5 Gbps, cerca de 10 vezes mais do que o USB 2.0. Em testes atuais (segundo o site Electronista), 25 GB de dados são transferidos em 14 minutos usando USB 2.0, mas os mesmos dados são transferidos em apenas 70 segundos com o USB 3.0. É uma velocidade assustadora, passando do Fireware e de muitos discos rígidos.  Além de consumir menos energia por natureza, as especificações do USB 3.0 permitem levar uma maior potência da máquina para o dispositivo, reduzindo a necessidade de um cabo de alimentação externo ou do uso de duas portas USB, comuns em alguns dispositivos comilões de energia.Dez vezes mais rápido, compatibilidade com dispositivos USB atuais.Imagine poder copiar o conteúdo equivalenteao conteúdo de um DVD em poucos segundos!...MAL POSSO ESPERAR!!heheVeja mais sobre as especificações em: http://www.usb.org/developers/docs/
