Silverstone ECM24-ARGB M.2 to PCIe Adapter Card Review

 Silverstone ECM24 ARGB card_2

The days where an SSD was a luxury are long gone. In fact, with how cheap solid-state drives have become, it’s perfectly viable to build a system with all solid-state storage. Now 2.5″ SSDs are great options for decently fast storage. However, if you want the best possible performance, M.2 drives are the way to go. The one limiting factor to M.2 drives are the number of slots on your motherboard. Given with newer generations motherboards such as Z490, you can get a board with upwards of three M.2 slots. But lower-tier motherboard and especially older motherboards may only have a single M.2 slot. So what do you do if you’re happy with your system, but you want more, fast storage. Well, Silverstone has you covered with their ECM24-ARGB M.2 NVMe SSD to PCIe X4 adapter card.

The Silverstone ECM24-ARGB is a PCIe expansion card that allows you to run a single M Key M.2 SSD in a PCIe slot on your motherboard and supports both AHCI and NVMe SSD, up to PCIe Gen 4. The ECM24-ARGB comes with an aluminum heatsink and several thermal pads designed for advanced cooling of your SSD. However, even going back a few generations, it seems there are plenty of options for motherboards with two or even three M.2 slots. So, does the Silverstone ECM24-ARGB offer more than just an extra M.2 slot? We ran several tests in an attempt to answer that question. So, let’s get into it. We’d like to thank Silverstone for supplying Thinkcomputers the ECM24-ARGB M.2 to PCIe adapter card for review.
