First time using a 3.0. USB External HDD

Hey guys, as the title says, I just want to know that my transfer speeds are optimized, when I transfer small stuff it goes up to 100+ MB/second, but when I transfer stuff in Gigabyte it is only 64-70 MB/second, googling USB 3.0. says it can go much faster, is this right?

It could be but it all depends on the drive your using some are a lot slower then others.

so it is because of the external drive that is does not go higher?
