Hello everyone. I intend to purchase a second Dell PC, this time is a T5810. I was told this model has HEDT platform. I would like to use 2*Samsung( EVO 950,960,970, or the OEM 951,961,971 ) 250GB M.2 PCIe SSD's in RAID mode. As far as I was told I need two adapters, can someone  please confirm this will work as mentioned? Use the above mentioned SSD's in RAID and boot OS from this. 

I was also told DELL has a RAID pcie adapter that can hold up to 4X nVME SSD's.
