Both quintuple and x10 are correct, depending on how you want to phrase it.

The spec's bit-rate is 5x faster, but "doubles" that increase by moving from half-duplex to full-duplex, for a total of 10x *bandwidth* -- used IF and only if the device needs bi-directional maximum data transfers.  Which most devices don't, so you'll SEE a slightly greater than 5x bandwidth increase from the bit-rate and handshaking-latency-eliminating-full-duplex change.  But not 10x in most devices.
