SD Card reader - what speed?

I'm thinking to upgrade to the inspiron 6000 (or even the 9300) from my current 8600, which still works excellent and is in brand-new condition (more than a year old), mainly because the SD card reader.

 

However, I need to know the speed it reads the card. Now in my 8600 I have a SanDisk 5-in-1 card reader which works by plugging in the USB 2.0 and reads extremely fast. But at work I have a Compaq Presario Desktop PC with a Built-in card reader, which reads very slowly - probably the USB 1.1 speed.

 

So can you tell me how fast they read in the new Dells? is a 512 MB card copied in less than 60 seconds or does it take 4-5 minutes?

 

Thanks for your replies.
