This drive expansion card 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 expansion 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.

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.
