Add U.2 NVMe storage to desktop or server

This x4 PCI Express adapter adds a SFF-8643 port so a 2.5" U.2 NVMe SSD such as the Intel SSD 750 series can be installed in a standard expansion slot. It targets IT professionals and system integrators who want enterprise-class storage without replacing the motherboard or chassis.

Requires a PCIe 3.0 or 2.0 slot with four lanes

The card operates as a PCI Express 3.0 x4 host adapter and is backward compatible with PCIe 2.0 motherboards. If the platform cannot supply a four-lane slot the drive will not reach its rated throughput, so verify the slot configuration before purchase.

Passive design draws minimal power

With no active cooling the adapter runs silently and adds negligible load to the system power budget. The low-profile bracket is included for compact builds, while the pre-installed full-profile bracket fits standard height cases.

Questions about this item

How does the x4 PCIe 3.0 link affect real-world throughput for a U.2 NVMe SSD?

The card runs at PCIe 3.0 x4, so a U.2 NVMe SSD can use up to four lanes of third-generation bandwidth; actual speed depends on the drive and the host slot.

Does the SFF-8643 connector limit the SSD to a specific PCIe generation?

The SFF-8643 port carries four PCIe lanes and is electrically compatible with both PCIe 3.0 and 2.0 motherboards, so the generation is set by the slot, not the connector.

What clearance is needed to install the card in a standard chassis?

The board measures .90 by 3.10 by 3.70 inches and ships with both a full-profile bracket installed and a low-profile bracket for slim cases.
