It should, support for USB 3.0 was included in linux kernel 2.6.31, 10.04 ships with 2.6.32. On a different discussion I'm loosely watching the new SSD drives that use SATA connections, some of them are blazingly fast. <a href="http://thessdreview.com/our-reviews/ocz-vertex-3-240gb-sata-3-ssd-review-raid-has-become-pointless/">http://thessdreview.com/our-reviews/ocz-vertex-3-240gb-sata-3-ssd-review-raid-has-become-pointless/</a> <div class="gmail_quote">On 25 April 2011 18:50, David <<a href="mailto:agora@justemail.net">agora@justemail.net</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Hi folks and thanks for the responses to my earlier questions about PDFs. Now that I assume updates will soon no longer be given for 8.04, I am planning to install 10.04 LTS, and to get a card installed in my existing computer so that it's USB 3.0 compatible, and to get a USB 3.0 external HDD. Does 10.04 work automatically (high speed) with USB 3.0?
