Samsung PM991a 512GB SSD M.2 2230 Internal Solid State Drive PCIe PCIe 3.0x4 NVME SSD For Microsoft Surface Pro 7+ Steam Deck - AliExpress
I tried the Samsung PM991 hack and it didn't work. Validate drive before I cut. Cut past the chips like other posters. Now drive only shows up as 1.1gb and won't format.
