The M.2 NVMe + M.2 SATA SSD PCIe x4 Adapter is a unique product with 2 very different M.2 Slot. It can offer the fastest boot or data access thru the NVMe SSD and at the same time provide very fast storage through the M.2 SATA SSD. It provides the link between PCIe 4 lanes of data path straight to the NVMe SSD resulting in super-fast data transfer and another M.2 interface for your M.2 SATA SSD. This adapter allows for flexible installation of an M.2 (NGFF) of different size like 42, 60, or 80mm in length with varying capacity. This M.2 adapter will give you the best performance possible for your system.
