The Skylake NUCs have faced plenty of issues since their introduction late last year. However, stability has improved with the latest BIOS updates. One of the issues with the early BIOS versions was the M.2 SSD slot being effectively limited to PCIe 2.0 rates despite the chipset supporting PCIe 3.0. The latest BIOS version resolves this issue. We had carried a detailed evaluation of different M.2 SSDs for usage in the Skylake NUC. At that time, the Samsung SSD 950 PRO was the only option for providing maximum possible theoretical performance - a NVMe SSD with a PCIe 3.0 x4 link. Since then, Toshiba has also entered the fray with the Toshiba OCZ RD400. The RD400 has already been put through our rigorous SSD evaluation suite. In this review, we take a look at how the 512GB version fares in the NUC6i5SYK.
