x4 PCI Express to M.2 PCIe SSD Adapter
Connect a PCIe M.2 SSD (NVMe or AHCI) to your computer through PCI Express for ultra-fast data access
Product ID: PEX4M2E1
Get ultra-fast data access by adding a PCIe M.2 SSD to your existing computer. This adapter lets you add a high-speed, 4-lane M.2 SSD (PCIe-based), such as a Samsung 950 Pro or Samsung SM 951, to a PC with an available x4 PCI Express expansion slot. You can mount the PCIe M.2 drive directly onto the adapter, giving you an easy and convenient way to improve your system performance and expand overall internal storage.
Boost your system speed and performance
The expansion card lets you take full advantage of the fast performance and compact size of PCIe M.2 internal solid-state drives. The adapter 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 2.0 and PCIe 1.0. 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 3.0 x4 NVMe (M Key) and PCIe-AHCI M.2 SSDs including 2242, 2260, 2280, and 22110 drives. The expansion slot adapter supports the most common drive sizes including 110 mm, 80 mm, 60 mm and 42 mm.
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.
The PEX4M2E1 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Frequently Asked Questions
Before You Buy
There are no known incompatibilities between this hard drive adapter and any SSDs or motherboards; however, certain SSDs and motherboards may be incompatible with each other. Before you use an SSD and motherboard together, you should check with the SSD and motherboard manufacturers for any potential compatibility issues.
For example, the Intel 750 series SSD may not work as expected when you use it with certain motherboards. For more information, refer to the Intel documentation for the 750 series located here: www.intel.com/content/www/us/en/support/solid-state-drives/consumer-ssds/000005729.html.
You can use this hard drive adapter to boot an operating system from; however, depending on the SSD and motherboard that you are using, you may need to update the driver or BIOS in order for the hard drive to be seen when you initially boot the operating system.
If you experience issues when you use the hard drive adapter to boot an operating system, check with the manufacturers of the SSD and motherboard for updates.
You should also check to make sure that the SSD and motherboard are compatible. For more information, refer to the following FAQ: https://www.startech.com/faq/hard_drive_accessories_m2_u2_compatibility.
Although M.2 SSDs come in similar form factors, only an M.2 PCIe drive with an M.2 NGFF M key will operate with this device. M.2 drives that are SATA or drives that have a different key position are not compatible with this device.
This device can adapt an M.2 PCIe drive to connect to PCIe connections, which is not possible for a SATA based M.2 drive. The key type refers to the connector type on the M.2 PCIe drive, and the M key can only be M.2 PCIe. It is important to check the specifications of the drive to see if it supports PCIe M key.
To fix this issue, a hotfix must be downloaded and installed. The hotfix will add native driver support for NVM Express (NVMe) drives that use the PCI Express (PCIe) bus in Windows® 7. We recommend that you contact the manufacturer of your NVMe drive to locate the download links and installation instructions for the hotfix associated with your drive.
