The new HP Z Turbo Drive G2 features the next generation PCIe SSD. This M.2 form factor device uses PCIe Gen3 x4 which enables performance levels greater than 2GB/s, which is roughly 4x greater than SATA SSDs. The Random Read performance is significantly improved also, due to the NVMe controller technology used on the device. This performance is available at a price that is comparable to commercial SATA SSDs.
