Can I use a USB 2 CD Burner with a USB 1 system?

[DPK]

I am just curious. My girlfriend's notebook is probably USB 1 and I am going to by a CD writer to back up her laptop and my PC. Will the CD writer still work with a laptop that has USB 1?

It might work, though it is going to be real slow. My Flash memory stick is USB 2.0, and works in USB 1.1 ports, but man it is VERY slow on transfers.

Slow as in USB 1 slow, or even slower because of the difference in formats?

Slow as in USB 1 slow. What difference in formats are you talking about?

It would be a good idea to buy a USB 2.0 PCI card, coz running a fast CD writer off a USB1.0 port will be like choking the hell out of the writer.

USB1 slow, if it doesn't refuse to work altogether. Usually 4X or 6X max, iirc.

Might want to get cardbus USB2.0 card.

USB2= upto peak 480Mbps
USB1= upto peak 12Mbps [1.5MBps] Cd x1 speed is 150KB/s.
If it was pure, you might get upto x10.
But I don't think so in practice.
LTC is right.

I have used an external burner that is usb 2.0 on a system with 1.0. I only burned at 4x as 6x is the probabale max for 1.0 and Nero gives me choices for 2x, 4x, then 8x. The same burner works at it's advertised speed on a 2.0 connection.
