￭ Converts one M.2 port (M key) into one PCI-E x4 interface
￭ Converts a second M.2 port (B key) into SATA interface
￭ Supports two M.2 SSD simultaneously
￭ Includes optional low-profile expansion slot
￭ No driver installation required
SilverStone’s ECM20 is an adapter designed for users wanting to utilize or add speedy M.2 devices such as SSD onto their existing PC or motherboard. In addition to supporting one M.2 device (M key) to run via the super fast PCI-E interface at up to 32Gbps, a second M.2 slot (B key) is available for connecting to a SATA III port for added storage potential. For users looking to have the fastest data access speed on a desktop computer, the ECM20 is a must have.
There are three types of M.2 SSDs, please make sure you know the difference between them and whether your system/motherboard support them before pairing these with your SilverStone product.
SATA (B key)
Used for SATA SSDs, and interfaced through the AHCI driver and SATA 3.0 (6 Gbit/s) port exposed through the M.2 connector.
PCI Express using AHCI (M key)
Used for PCI Express SSDs and interfaced through the AHCI driver and provided PCI Express lanes, providing backward compatibility with widespread SATA support in operating systems at the cost of not delivering optimal performance by using AHCI for accessing PCI Express SSDs.
PCI Express using NVMe (M key)
Used for PCI Express SSDs and interfaced through the NVMe driver and provided PCI Express lanes, as a high-performance and scalable host controller interface designed and optimized especially for interfacing with PCI Express SSDs. NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and complementing the parallelism of contemporary CPUs, platforms and applications.
The following SSD models have been tested and verified by SilverStone to work optimally with the product presented on this page.
Note: ECM20’s 'M' key is for use only with PCI-E SSD, 'B' key is for use with only SATA SSD.
Note: B key SSD requires SATA 7 pin cable connected to motherboard to function.
Note : M.2 PCIe-NVMe mode SSD requires the use of Intel® 9 series (Z97 H97 Z170 X99) or higher version chipset motherboard with Windows 8 or higher version operating system.
Note : If your operating system is incompatible with the expansion cards developed by SilverStone, such that your device can not be detected or recognized, please update your motherboard’s driver or BIOS to the latest version. You may also try executing compatible mode in your operating system and select previous versions of operation system to install driver required by the expansion cards.
