Hi,
I have a USB 3.0 enclosure for a 2.5" HDD, and I would like to know if I should get a SATA III drive for it or not. Will I maximize the USB 3.0 by having SATA III connection, or would it essentially be the same to use the slower SATA II? I know II is up to 3 gb/s where III is up to 6 gb/s, but I didn't know how much these figures really come in to play when using USB.

Thanks!
