![]() See Figure 3 below for reference related to the M Key connector on motherboardĮven if the M.2 connector with only an M key can accept a SATA SSD or a PCIe NVMe SSD, the system BIOS must also be capable of supporting a PCIe NVMe SSD. The WD Black PCIe SSD does not have a B notch and therefore, the B key on the SSD connector will prevent it from being inserted. To support a WD Black PCIe SSD, the system must have an M.2 connector with only an M key. The table and figures below shows mechanical compatibility between the SSD connector types and SSD devices.įigure 1: SATA M.2 2280 SSD with B+M notchesįigure 2: NVMe M.2 2280 SSD with M notchs However, the specification allows the SSD connector to be implemented to support the following:Īn M.2 SSD connector can have B+M key, or an M key only. An SSD M.2 connector for SSD uses keys in position B and M to prevent a non-SSD device from being plugged into it. To help plug in the correct peripheral type into the target M.2 connector, the standard defines keys A through M on the connector and corresponding notches A through M on the device. However in both cases, it must be securely screwed down with an appropriate retaining screw. Thus, the WD Black PCIe SSD can fit into a M.2 2280 or larger slot. It is a standard 22mm wide x 80 mm long, and up to 2.4mm tall.All M.2 NVMe SSDs are a standard 22mm, however, other products may vary in length as 30, 42, 60, 80 or 110 mm.Ī longer slot space can generally accommodate a shorter device. The WD Black PCIe SSD is an M.2 2280 form factor. ![]() These requirements are further explained in the sections below. It is best to contact the motherboard or PC manufacturer for possible updates to the BIOS and Chip set and ensure the operating system is current with the latest patches and updates prior to installation of new hardware. ![]() On software side, it is important to know, the drivers are a function of the host BIOS and Chip set on the motherboard and Operating System (OS) installed must support PCIe NVMe SSDs. ![]() On hardware side, the motherboard must include an M.2 connector that supports PCIe and NVMe SSDs. There are both hardware and software requirements for WD Black PCIe SSDs. ![]() This article explains how to determine if the computer supports a WD Black PCIe SSD*END ![]()
