Does Precision 7710 second PCIe SSD run on SATA bus?

Hi, 

I'm custom configuring a Precision 7710 system and trying to pick a 2nd SSD.  

The boot drive will be the "512GB M.2 PCIe NVMe High Performance Class 50 Solid State."   I believe it's connected directly to the PCIe bus buss via an M.2 connector.  

For the second drive I'm considering the "512GB M.2 PCIe NVMe High Performance Class 50 Solid State Drive with Interposer."   However, I looked up Interposer and it appears to be a SATA adapter. So, does this mean the 2nd drive will be running on the SATA bus?  If so, this high performance PCIe SSD will not be able to live up to it's full potential due to the SATA bottleneck, right?   I would be better off just getting a cheaper SATA drive, no?

Thanks!
