Get ultra-fast data access by adding a PCIe M.2 SSD to your existing computer. This adapter lets you add a high-speed, 4-lane M.2 SSD (PCIe-based), such as a Samsung 950 Pro or Samsung SM 951, to a PC with an available x4 PCI Express expansion slot. You can mount the PCIe M.2 drive directly onto the adapter, giving you an easy and convenient way to improve your system performance and expand overall internal storage. The expansion card lets you take full advantage of the fast performance and compact size of PCIe M.2 internal solid-state drives. The adapter connects directly to your computer motherboard to support an M.2 PCIe-based SSD (NVMe or AHCI) through ultra-fast x4 PCIe. The adapter is compatible with PCIe 3.0 motherboards and is also backward compatible with PCIe 2.0 and PCIe 1.0. With the M.2 PCIe based drive in place, the adapter gives your computer a significant speed boost. The adapter supports PCIe 3.0 x4 NVMe (M Key) and PCIe-AHCI M.2 SSDs including 2242, 2260, 2280, and 22110 drives. The expansion slot adapter supports the most common drive sizes including 110 mm, 80 mm, 60 mm and 42 mm. The expansion card is equipped with a full-profile bracket and includes a half-height/low-profile bracket, for installation in small form-factor computers. The x4 PCI Express to M.2 PCIe SSD adapter is backed by a StarTech.com 2-year warranty and free lifetime technical support.
