Last fall, the Taiwanese manufacturer SilverStone, which will probably be known to most for its cases, coolers and fans, introduced two SSD adapter cards. With the help of the adapters, an SSD in M.2 format can be used. The SSD is connected via PCIe, you need a free PCIe 3.0 x4 or alternatively a free x16 slot on your motherboard. The adapters are the rather minimalistic SST-ECM21-E and the SST-ECM24-ARGB, which offers a heat sink and ARGB lighting in addition to the M.2 slot itself.
We have both adapters in review, going into additional features and comparing the performance of the NVMe SSD connected via the adapters with direct operation in the motherboard’s M.2 slot.

SST-ECM21-E in detail
The SST-ECM21-E adapter card comes together with a shorter slot bracket and instructions in a compact cardboard box. Screws are also included, but are not needed thanks to the tool-less mounting.
The PCB is black, and M.2 SSDs in four lengths, up to a maximum of 80 mm, can be mounted. Everything is already prepared for the common M.2-2280 format. If you want to use shorter SSDs, you can of course use the bracket in a different place. Alternatively, the included screws can also be used for mounting.
Overall, the SST-ECM21-E adapter card concentrates on the essentials. You get another M.2 slot with this, but you have to do without further features.
