What is the StarTech.com M2D20 M.2 Adapt Card?
The M2D20 is a PCIe adapter card that lets you install an M.2 NVMe SSD into a standard PCI Express slot for high-speed storage expansion.
Which M.2 SSD form factors are supported by the M2D20?
The M2D20 supports M.2 2230, 2242, 2260, and 2280 SSDs with an M-key socket.
Does the M2D20 support SATA as well as NVMe M.2 SSDs?
No. The M2D20 only supports PCIe NVMe Gen3 x4 M.2 SSDs and is not compatible with M.2 SATA drives.
What interface and maximum transfer speeds does the M2D20 provide?
It provides a PCI Express 3.0 x4 interface for up to 32 Gbps of data throughput.
Which PCIe slot is required for installing the M2D20?
You need an open PCIe 3.0 x4, x8, or x16 slot on your desktop motherboard.
Are additional drivers required to use the M2D20?
No. The M2D20 uses native NVMe drivers built into Windows, macOS, and most Linux distributions.
How do I install an M.2 SSD on the M2D20 card?
Insert the M.2 SSD into the M-key slot at a 30° angle, secure it with the included screw, then install the card into a PCIe slot.
