x4 PCI Express to SFF-8643 Adapter for PCIe NVMe
U.2 SSD
Product ID: PEX4SFF8643
Unleash the performance of your desktop PC or server with this enterprise-class drive adapter. By
providing compatibility with newer U.2 NVMe SSDs, such as the Intel® SSD 750 series, you can gain
faster read/write speeds and higher productivity levels for data-intensive applications.
Upgrade your system cost-effectively
This drive adapter provides an ideal way to upgrade legacy motherboard platforms and your existing
computer system, by adding compatibility for newer U.2 NVMe SSDs, which are designed to meet the
high-performance needs of today’s data centers and enterprise-level applications.
The adapter card enables IT professionals and system integrators to upgrade their computing
infrastructure by installing the adapter card into the PCIe slots on desktop PCs or servers. Upgrading,
rather than replacing computing infrastructure, provides a cost-effective way to enhance your system’s
performance.

U.2 NVMe SSDs also offer superior energy efficiency, providing an advantage to companies looking to
reduce energy costs.
Gain higher productivity through faster read/write speeds
Companies and organizations with intensive file workloads can achieve greater productivity by upgrading
their data center or enterprise-level applications with U.2 NVMe SSD capability. U.2 SSDs are up to four
times faster than SATA SSDs, providing extremely fast read/write speeds, high-speed file access and
transfers, and rapid boot times. U.2 NVMe SSDs are also more reliable than SATA hard drives, so less
time is spent waiting for computers to boot, or applications and files to load.
Through U.2 NVMe SSD capability, the drive adapter brings enhanced productivity for numerous data-
heavy applications. Office professionals, from architects and engineers to healthcare professionals, can
quickly access and edit large documents, spreadsheets, or 3D models and renderings. Creative
professionals, including content creators and graphic designers, can work more productively on photo
editing, video production and editing of large image or audio files.
The drive adapter also saves time for gaming enthusiasts, with much faster launch times and level
changes.
Installs easily into your PC’s 4-lane PCIe expansion slot
The U.2 SSD adapter lets you add a PCIe NVMe 2.5 in. SSD to a computer system that doesn’t natively
support U.2 PCIe NVMe. The adapter simply connects to your computer’s 4-lane or greater PCI Express
slot and enables you to connect a U.2 SSD to your PC through the provided SFF-8643 interface, using an
SFF-8643 to U.2 cable. The PCIe 2.5 in. NVMe SSD adapter is compatible with PCIe 3.0 and PCIe 2.0
motherboards.
The drive adapter comes with a full-profile bracket (preinstalled), and also includes a low-profile bracket
that makes it easy to install the card in a small form-factor computer.
The PEX4SFF8643 is backed by a 2-year StarTech.com warranty and free lifetime technical support.
