My BOOK USB 3.0 average speeds?

Hey all! I wanted to get some input from users on average speeds on transferring files from PC to My BOOK USB 3.0 2TB. The highest I have ever gotten was 98MB/s… IT can range anywhere from 15MB to 98MB/s. I would say I average around 40-50 MB/s.

Anyone getting HIGHER rates? 

Thanks all.
