NVMe connects directly (via a PCIe switch) to the native PCIe Gen 2 single lane exposed by the Broadcom SoC and there is an overall 10% improvement in performance in using this bus over the fastest SATA and mSATA SSDs. We wanted to deliver a no compromise solution that squeezed every bit of performance out of the Broadcom SoC and we found both in testing and in practical everyday use this improvement is noticeable. Despite being a little more expensive NVMe is without question the superior solution.
