- What is the maximum speed of pcie3.0x4
- The theoretical maximum read or write speed of PCIe3.0x4 is 4GB/s. Regardless of protocol overhead, it can transmit 4GB/4K 4K IOs per second. This value is 1M, which means the theoretical maximum IOPS is 1000K. Therefore, no matter what media is used in the underlying layer of an SSD, whether it is flash or 3D xpoint, the interface speed is only so low, and the maximum IOPS cannot exceed this value.
