SILVERSTONE ECM21 (SST-ECM21)

Features of SILVERSTONE ECM21 (SST-ECM21)

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)only support to install this type

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)only support to install this type

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.

1. Converts M.2 port (M key) into one PCI-E x4 interface
2. Includes an optional low-profile expansion slot
3. No driver installation required
