With older platforms in mind or users who simply want to add M.2 slots to their systems, SilverStone has just introduced the thin SST-ECM28 expansion card solution. As a dual M.2 SSD Riser card, it is capable of accommodating one M-key NVMe and one B-key SATA drive, as well as a variety of board types from 2230 to 2280.
While this isn’t the first time we’ve seen a dual M.2 SSD expansion card, we’ve never seen such a compact style before. As shown, the SST-ECM28 is capable of mounting one M.2 SSD on each side.
The M-key NVMe drive bits are led from the PCIe x4 lane (compatible with slots such as x8 / x16), while the B-key M.2 drive bits require connection to the SATA port on the motherboard.
To overcome the lack of PCI baffles, SilverStone also cleverly equipped the SST-ECM28 with a PCIe x16 slot PCB tailgate (similar to a graphics card).
Finally, the SilverStone SST-ECM28 Riser card is compatible with M.2 SSDs from 2230 to 2280 board models. However, if you need to move the host around a lot, please also take care to check if it comes loose due to vibration before using it.
