The Lenovo IdeaPad 5-15ABA7 Laptop Supports Single or Dual Drive Configurations Depending on the Battery Installed. (One 2.5" Solid State Drive or Hard Drive + One M.2 NGFF (2280) or (2242) Solid State Drive with the Smaller 57Whr Battery Installed) or (One M.2 NGFF (2280) or (2242) Solid State Drive with the Larger 76Whr Battery Installed) Note: Models that have the larger 76Whr battery installed do not support 2.5" Drives due to the larger battery occupying the 2.5" Drive bay. The M.2 2242 Drive uses a adapter bracket p/n AM2UZ000F00 to accommodate for the larger M.2 2280 slot size. If the 2.5" Drive was not installed from Lenovo in models with the smaller 57Whr battery installed, you will need the 2.5" Drive caddy p/n 5B40S21974 and cable p/n 5C10S30033 for installation. M.2 Drives with PCIe Generation 4.0 x4 performance are downgraded to closer to PCIe Generation 3.0 x4 performance due to AMD platform limitations.
