The newest offerings from CPU vendors are adopting the PCIe 4.0 interface for storage and other peripherals, and with good reason, as this new standard offers twice the bandwidth of PCIe Gen3. The PM9A1, the industryโs first PCIe Gen4 drive delivered to the OEM market, maximizes the potential of the latest generation of processors. It offers up to 100% improvement in sequential read speeds compared to high-end Gen3 drives, enabling faster file operations when working with data intensive use cases such as video editing, 3D rendering and simulations, and gaming. It also boosts random read speeds by up to 50%, cutting downloading times and improving system response.
