U.2 NVMe adapter for PCIe 4.0 x4

This adapter connects a U.2 NVMe SSD to a PCIe 4.0 x4 slot using the SFF-8639 interface. It provides a direct expansion path for enterprise or high-performance storage drives in a desktop or workstation chassis. The card is supplied in black and listed as new condition from 2021.

Not for USB or serial connections

The specifications list a changer type of USB to DB9 (RS-232), which does not match the NVMe adapter function described in the title. Buyers who need a genuine USB-to-serial converter should look elsewhere, as this product will not serve that purpose.

Questions about this item

What does PCIe 4.0 x4 mean for my NVMe drive speed?

PCIe 4.0 x4 provides up to 8 GT/s per lane, giving the NVMe drive its full bandwidth potential when the host system also supports PCIe 4.0.

Does the SFF-8639 connector limit the adapter to U.2 drives only?

The SFF-8639 connector is the standard U.2 interface, so the adapter works with U.2 NVMe SSDs that match this form factor.
