You wll need to go into the Bios setup, Undr the ADVANCED tab, to check the Boot Configuration settings to see if booting from USB is supported.
To enter Bios setup
1 Turn on (or restart) your computer.

2 When the blue DELLâ„¢ logo appears, press <Del>.

As far as USB 2.0 and a 5400 ide drive the USB 2.0 tops out at 420Mbs(Megabits/second)but in reality no device on a USB chain can use more than two-thirds of the bandwidth. That means bandwidth is usually nearer 320Mbs.  
5400 ide if ATA100 would be 100 MBs(MegaBytes/second)
to translate the Bytes too bits the USB bandwidth is tops 52.5 MBs(MegaBytes/Sec) or 40 MBs if the two thirds rule is used.
So the IDE drive is faster.
