RIITOP

RIITOP 4-Port NVMe PCIe 4.0/3.0 x16 Expansion Card with Heatsink

SKU CH-HB4B-X3J9T

Adds four M-key NVMe SSDs via a PCIe 4.0/3.0 x16 slot with bifurcation support and an included heatsink

  • TypeController Card
  • Adds four M-key NVMe drives at 32 Gbps each
  • Supports 2280, 2260, 2242 and 2230 form factors
  • Works with Windows, Mac OS and Linux
  • Requires motherboard PCIe x16 bifurcation to x4x4x4x4
  • Includes heatsink for sustained high-speed operation

Four-Port NVMe Expansion Card

This PCIe x16 adapter adds four M-key NVMe slots to a desktop or workstation. It targets builders who need high-density flash storage on a single expansion slot and whose platforms support PCIe bifurcation. The card accepts 2230, 2242, 2260 and 2280 drives.

Bifurcation and Lane Limits

The board requires a motherboard that can split a x16 link into four x4 links and expose the setting as "PCI-e x4x4x4x4" in firmware. Without that capability only the first drive will be detected. The host CPU must also provide enough lanes to feed all four ports simultaneously.

Capacity and Thermal Headroom

A bundled heatsink spreads heat across all four installed SSDs during sustained transfers. Each port delivers a 32 Gbps link so four Gen 4.0 drives can run at full speed, while Gen 3.0 drives operate at their native rate. SATA-based M.2 modules are not supported.

Questions about this item

Which SSD sizes does this card accept?

The card fits M.2 M-key NVMe drives in 2280, 2260, 2242 and 2230 form factors; SATA-based B+M key SSDs are not supported.

What does the 4x32Gbps claim mean for each installed drive?

Each of the four slots can run at a full PCIe 4.0 or 3.0 x4 link, giving up to 32Gbps per drive when the platform provides enough lanes.

What motherboard feature is required to use all four ports?

The board must support PCIe x16 bifurcation and be configurable to x4x4x4x4 in the BIOS, which is common on X299 and X399 platforms.
