SilverStone ECM20 Overview
Inside the ECM20’s box you’ll find the card itself, a low-profile bracket, a fairly useless “manual”, and two small packages of mounting screws.
Large stickers on the card helpfully designate the SATA m.2 and PCI-E m.2 slots. There are no electronic components on the front of the card.
Removing the stickers is necessary to use the card, but they leave residue you’ll need to clean off.
The rear of the card has the only electronic components: a few surface-mount capacitors, probably used as filters.
Each of the small plastic pouches included has these three components, which you’ll need to mount the SSDs. You’ll also need a really small Philips-head screwdriver, and, ideally, a very small nut driver, although small needle nose pliers will do in a pinch.
You’ll add these components to different places on the board depending on the size of the SSD you’ll be mounting. SilverStone provides no guidance on how to “assemble” a mounting point, but I eventually figured it out.
Here’s what it looks like ready to go, with a SATA m.2 drive mounted in the top slot and our Samsung 950 PRO NVMe SSD mounted in the bottom slot. Note that the SATA m.2 drive must be connected to a SATA port on your motherboard with a SATA cable.
So how does the performance of this card compare with using the native ports on our MSI Z170 motherboard? Let’s find out.
