The ZDNet article above got an update, an offical response from Lenovo. I copied it from there: UPDATE 9-21-16 7:25 PDT: Comment from Lenovo: "To improve system performance, Lenovo is leading an industry trend of adopting RAID on the SSDs in certain product configurations. Lenovo does not intentionally block customers using other operating systems on its devices and is fully committed to providing Linux certifications and installation guidance on a wide range of products -https://support.lenovo.com/us/en/documents/pd031426 https://support.lenovo.com/us/en/documents/pd031426. Unsupported models will rely on Linux operating system vendors releasing new kernel and drivers to support features such as RAID on SSD." So no Microsoft involvement, just a lack of drivers on Linux's part. Although Lenovo could offer a method for owners to switch the SSD from RAID to AHCI mode to improve compatibility.]
