<p>➀ Microchip unveiled the Adaptec SmartRAID 4300 at FMS 2025, a PCIe Gen4 x16 NVMe RAID controller without onboard drive connectivity, marking a departure from traditional designs.</p><p>➁ The controller performs XOR parity calculations on-device, allowing data to flow directly from the CPU to NVMe SSDs, bypassing traditional bottlenecks and improving performance (e.g., 27M+ IOPS in Linux).</p><p>➂ This approach aligns with industry trends adopted by GRAID and Pliops, leveraging PCIe efficiency and requiring colocation with SSDs on the same CPU for optimal latency reduction.</p>
