Can we install Western Digital WD Blue NVME SN550 250GB M.2 2280 PCIe Gen3 Internal Solid State Drive (WDS250G2B0C) on Acer Aspire 3 series A315-51 Laptop ?
As far as I know, the Acer Aspire 3 A315-51 has an M.2 SATA III slot adapter for a B+M key SSD.
The WDS250G2B0C is a M-key SSD, so it will physically fitt, but it will work only with SATA speed.
You also can replace the HDD with a 2.5 Inch SATA SSD.
You can use:
WD Blue 3D NAND SATA SSD (formaat: 2.5 inch SATA or M.2 2280 SATA)
