From: Roy on 26 Jan 2010 05:36 Hello group Currently we are still having the USB 2.0 set up for our PCs? When will this USB3 starts to be placed in PCs? What will be the backward compatibility issues with the USB 1.0. and USB 2.0. I heard that it has more connectors? Would USB 3.0 be more power hungry than USB 2.0? hence in laptops it may drain more battery juice? TIA Roy

If you want speed with little CPU usage, wouldn't using an external eSATA connection be better? As eSATA is 6 times faster than USB2. -- Bill Asus EEE PC 702G4 ~ 2GB RAM ~ 16GB-SDHC Xandros Linux (build 2007-10-19 13:03)

As eSATA is 6 times faster than USB2. I just got a newsletter from Asus and they have a laptop with USB3. And newegg has them for under 1000 bucks. Claim is USB3 is 10 times faster than USB2. Gee that has everything else like firewire and eSATA beat if true. http://www.newegg.com/Product/Product.aspx?Item=N82E16834220696&Tpk=N61Jq -- Bill Asus EEE PC 702G4 ~ 2GB RAM ~ 16GB-SDHC Xandros Linux (build 2007-10-19 13:03)
