I was about to return this item due to M.2 PCIe didn't work. I used my SK Hynix PC601 M.2 ssd which is working fine with NUC7i5 but it didn't work with NUC8i5. To make sure if it is damaged or defected, I I tried with other m.2 SSDs(from Intel and Crucial) and they worked fine. I've ordered new one but from WD(hot deal).I'm currently using it with 180GB M.2. it's very quiet and fast enough to play some games like minecraft java edition. I'm using it with Ubuntu installed.
