NV9511 connects PCIe 4.0 to M.2 M key connector, It connects a PCIe M.2 SSD to your computer through an available x4 PCI Express expansion slot to boost system speed and increase internal data storage Get ultra-fast data access, ideal for gaming or high-performance workstations, Install your operating system on an M.2 PCIe based drive for fast access, while keeping larger platter drives available for bulk storage Boost your system speed and performance The expansion card 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 3.0 and PCIe 2.0. With the M.2 PCIe based drive in place, the adapter gives your computer a significant speed boost. Supports PCIe M.2 SSDs The adapter supports PCIe 4.0 x4 NVMe (M Key) and PCIe-AHCI M.2 SSDs including 2230, 2242, 2260, 2280, and 22110 drives. The expansion slot adapter supports the most common drive sizes including 110 mm, 80 mm, 60 mm, 42 mm and 30mm. Easy to install 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. Applications Increase the internal storage capacity of your standard or small form-factor computer. Access and recover data from almost any M.2 SSD, such as drives pulled from laptops and other computers. Optimize your system for I/O intensive applications such as office suites, photo and video editing, and media players.
