[OBasel]

Here's one I found that's SATA: Samsung PM871 512 GB SATA III 6 0Gbps 2 5" SSD MZ 7LN512HCHP | eBay and another m.2 Samsung PM871 512 GB PCIe SSD M 2 NGFF MZ NLN5120 | eBay both are cheap. Anyone know what they might be?

I believe this was an OEM only part that Samsung manufactured for IBM laptops. The sticker on both drives even state Lenovo.
