Thanks for the info but that didn't answer my question. My question was what is the original SSD that comes with Microsoft Surface pro 8. As far as I know SP8 comes with Kioxia SSD but mine came with Samsunghttps://www.notebookcheck.net/Samsung-PM991-MZ9LQ256HBJQ-SSD-Benchmarks.528170.0.html
^ Samsung's SSD's are higher in pedigree. Not sure if you want something lower in tier when in comes to build quality. On a side note, it's possible that vendor's options for SSD's needed reassessment and they sourced from Kioxia. I see other listing on the www with an SK Hynix SSD.
