Hi @shravan_dell you have encountered Alienware 17 R3 2016 Dell logic. Storage has 2.5" bay slow SATA interface, both M.2 slot interfaces have slow SATA and fast PCIe Gen3 x4 NVMe interface. Having an ultrafast read/write M.2 PCIe Gen3 x4 NVMe OS(C:) boot drive is the best option. (Pointless getting the more expensive Gen4 NVMe that will be demoted to run at Gen3 NVMe read/write speeds.)
The system will take either M.2 SATA or M.2 NVMe drives. In most cases, installing an NVMe drive alongside a SATA drive means the NVMe must be used as the boot drive.
If you're planning to clone over the existing install, be sure you remove the SATA drive before booting for the first time.

Even more simpler.
it accepts anything that fits in the m.2 slot that is either NVMe or SATA. But the NVMe must be Gen 3
