Performance Analysis of SAS/SATA and NVMe SSDs

Chris Evans reviews a performance analysis paper, breaking down the performance gains of NVMe vs SATA NAND disks in databases. This includes a look at real world applications. It shows the benefit of the reduced complexity and overhead of NVMe compared to SATA on otherwise identical storage media. As Chris notes, the lower CPU utlization and wait times have led to companies like E8 Storage and Excelero to develop new storage architectures. And in the HCI space, Scale Computing and X-IO are finding new ways to use the compute.
