HighPoint Technologies, Inc. R1204 RAID controller 4x M.2 PCIe 3.0 x8

Four M.2 slots on one card

The Rocket 1204 adds four M.2 NVMe ports to any standard PCIe 3.0 x8 slot. Each port receives a dedicated PCIe 3.0 x4 lane through an onboard Broadcom switch, so no motherboard bifurcation is required. It suits workstation and server builders who need dense local storage without proprietary hardware.

PCIe 3.0 x8 host link

The host interface caps aggregate throughput at eight lanes of PCIe 3.0, limiting total bandwidth to the x8 ceiling even though each M.2 slot is wired for x4. Workloads that saturate multiple drives simultaneously will contend for the shared upstream link. The card fits full-height slots and measures 7.68 by 4.38 by 0.73 inches.

Supports 2242, 2260, 2280 and 22110 drives

Four M.2 NVMe SSDs of any listed length install directly, single or double-sided, with passive cooling only. The x8 host link provides ample headroom for mixed read and write workloads across two or three drives; sustained full-speed operation on all four drives simultaneously will hit the upstream bottleneck. Native NVMe drivers are included for Windows 10 or later, Linux kernel 3.10 or later, macOS 10.13 or later and FreeBSD 12.1 or later.
