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 speedsCompanies 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 slotThe 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.The StarTech.com Advantage
