Overall you'll get the same performance from an ATA-133 drive though a USB2.0 cable or though an EIDE cable.
Now if we're talking SATA then there is no question which is faster.

actually, it's not like SATA drives are all of a sudden faster than the 50MB/sec quote you posted. that number is generally a limitation of today's hard drives, not the interface. now if you're doing a raid setup, then those rates might actually mean something, but they don't without that.
also, usb cables can theoretically transfer data at 480mbps, but many motherboards that have usb do not come close to this: the fastest ones tend to be around 300mbps, which would give you 37.5MB/s.
Jam it back in, in the dark.
