My R7 with three m2 nvme drives, two installed via adapter (pcie is bootable too btw) [IMAGE]BEFORE[IMAGE]AFTER[IMAGE]Samsung 970 Evo[IMAGE]SM961[IMAGE]PM981
I see from other answers on this topic that a NVME PCIe SSD will work.    However, in looking at the Aurora R7 Setup and Specifications PDF document, it shows that the M2.2280 slot appears to be limited to 2TB and SATA ACHI 6Gbps (I don't know what the U.2 drive is, but that is showing compatible with NVME PCIe up to 32 Gbps, but limited capacity of 280GB drive).    Does this mean that you do not get the benefit of faster read/write speeds yielded by the NVME PCIe SSD's, and so I should just look for a SATA 6Gbps SSD in the M2.2280 form factor? (i.e. is it a waste of money to get the more expensive NVME, PCIe SSDs as this document seems to indicate that slot is only SATA 6Gbps?)   I would like to use this drive for Windows as well as all applications, programs and games - will be looking at getting a 2TB (although a 1TB should suffice...).   Thank you for your time!
