EDIT: PROBLEM IS SOLVED, NO NEED TO READ IF U KNOW THE ANSWER.

Will a usb 2.0 pci really give me apeeds upto 480Mbps. I plan to get a usb casing and use my old 10Gb harddisk as external backup.
Now this page claims usb 2.0 gives 40 times the speed of usb 1.1

But how can that be possible since the harddisk's read/write speed never goes above 5 mb/s :wacko: . In other words just by sing using usb2.0 instead of ide, data transfer will increas 40 times?
isit ture or am i confusing different things

http://cgi.ebay.in/w...5223721041&rd=1

  Fast data/files access and transfer rate up to 480mb/Sec


thanks

it will be the speed that the drive says, not the type of connection

No. The hard drive can only access the data so fast. Speed is always limited by your slowest component.

It's like trying to take an Austin Mini (the old Mr. Bean car) and putting it on the Autobahn. No matter how hard you push the car, it'll only go so fast.
