What do the speed and other performance differ between USB 1.1 and 2.0?

 

Albert

USB 2 is theoretically 40 times faster than USB 1.1 with a transfer speed of 480Mbps.

 

While it's probably not quite as fast as that in real world use the difference is still very apparent when moving large data files.

I corrently have a problem, I have a external harddrive using USB 2.0, but my USB socket on my laptop is 1.1, I was thinking to change it, but unlike desktop, I dont know how to....

 

Is there any device, method to do such?

The first thing to do is to find out if your motherboard will support USB 2 hardware.

Here's a load of info on USB - http://www.microsoft.com/windowsxp/using/networking/learnmore/jones_02august05.mspx

 

If you want to run USB2 devices on a laptop with USB1 ports you'll have to get a USB2 PCMCIA card. Here's an example - http://www.bixnet.com/2poruspcmcic.html. This won't have the full performance of a true USB2 bus though.

Awwww... I wanted him to ask me if his motherboard supported USB 2

 

Anyway, a caution from that page:

 

Note: Make sure your laptop/notebook computer PCMCIA slot supports 32-bit CardBus before you order this product. Your manual or manufacturer of the laptop/notebook is the best place to verify the type of your laptop/notebook PCMCIA slots. Most laptops made after 1998 have 32-bit Cardbus PCMCIA slots.

Thx Mossoi for your help...

 

but how much slower does that PCMCIA card differ compared with true USB2?

To Sayonara, mine does support, I bought it in 2002...

The specs for that card claim that it runs at the same speed as a USB2 bus.

 

See if you can find any independent benchmark tests for it.
