Micro SATA Cables PN # SFF-993-U2-4L

The U.2 (SFF-8639) interface is a high-speed data transfer standard that is used to connect solid-state drives (SSDs) and other storage devices to computer systems. It supports data transfer rates of up to 32 Gbps and provides a scalable interface for future storage devices.

A PCI-e 4 Lane Adapter is a hardware device that allows the U.2 interface to be connected to a computer system via the PCI Express (PCI-e) bus. The PCI-e 4 Lane Adapter provides four lanes of PCI-e connectivity, which can support data transfer rates of up to 16 Gbps per lane.

The U.2 to PCI-e 4 Lane Adapter typically consists of a printed circuit board (PCB) with a U.2 connector on one end and a PCI-e 4 Lane connector on the other end. The adapter is designed to fit into a PCI-e slot on a computer's motherboard, allowing the U.2 device to communicate with the system's processor and other components.

When a U.2 device is connected to a computer via a PCI-e 4 Lane Adapter, the system treats the device as a standard storage device. The operating system can access the device's data as if it were stored on a local hard drive, allowing the user to take advantage of the device's high-speed data transfer rates.
