I'm confused over some of the storage options on my new R15.  I was expecting two M.2 slots but I guess one is being used by wifi.  So I'm looking at this: https://www.dell.com/support/manuals/en-bz/alienware-aurora-r15-desktop/alienware-aurora-r15-setup-and-specifications/storage?guid=guid-12cf2b7a-17bd-4537-b0aa-c1f3aee7967a&lang=en-us

It says you can have two 2.5-inch hard drives BUT only up to 2TB.  Is that accurate?  I'd love to drop a pair of WD RED SA500 at 4TB in to the system...Anyone know the part number for the 3.5-inch to two 2.5-inch conversion kit?

TIA
