SilverStone M.2 to PCI-E Express Card x4 Expansion Card

Faster Storage Upgrade

SilverStone’s ECM25 is an 1U adapter card designed for users wanting to utilise or add speedy M.2 devices such as SSD onto their existing PC or motherboard. ECM25 supports M.2 device (M key) to run via the super fast PCIe interface for added storage potential. For users looking to expand their M.2 capacity with fastest interface possible in low profile format, the ECM25 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.

• Converts one M.2 port (M key) into one PCIe x4 interface.
• Only 32mm tall when installed, easily fits in 1U or Slim chassis.
• Built-in LED indicator for showing PCIe NVMe status.
• Supports 2230,2242,2260 and 2280 length M.2 SSD.
• No driver installation required.

Sata (B key) (Not Supported)
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) (Supported )
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) (Supported)
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.
