U.2 (SFF-8643) to M.2 PCI Express 3.0 x4 Host
Adapter Card for 2.5” U.2 NVMe SSD
Product ID: M2E4SFF8643
This PCI Express U.2 to M.2 adapter makes it easy to install a high-performance U.2 PCIe-NVMe SSD into
your desktop PC or server and connect the drive through an M.2 PCIe x4 slot on your motherboard. By
creating compatibility with newer U.2 NVMe SSDs, such as the Intel® SSD 750 series, this enterprise-
class drive adapter enables you to gain faster read/write speeds and higher productivity levels for data-
intensive applications.
Gain faster system performance
This drive adapter card lets you optimize your system performance by harnessing the increased speed
and low latency of a U.2 PCIe-NVMe SSD (compared to regular platter drives), by adding a U.2 interface
to your system.
