FortiCache Sizing

Hello, I have one question related to the sizing off the forticache. I´m looking on two documents from fortinet, one is the forticache datasheet (the last one 2017, the one who is linked in the website) and the other one is the Fortinet Product Guide_Jan2017. In the datasheet it say that the forticache 400E has a Throughput 500 Mbps, but in the product guide say Throughput 100 Mbps, which is the correct value?

Thanks
