Introduction: Built on the same PCB design and PCIe Gen5 switching architecture, the Rocket 1604A and Rocket 7604A deliver full Gen5 x16 performance in one of the industry’s shortest 4× M.2 add-in card form factors—over 40% shorter than typical solutions—without compromising cooling or reliability. Both products support up to four dedicated Gen5 M.2 SSDs. The Rocket 7604A adds an extra layer of flexibility with dual-mode operation, allowing users to run native OS NVMe drivers
