SilverStone doesn't often put out storage solutions but with the launch of USB-C, we have a few new solutions in house, and we are starting off this batch with the new SST-MMS01.

The MMS01, as I will call it for lack of shortness, is an enclosure built from the ground up to be durable. Its number one mission is to protect whatever 2.5" drive you choose to install, whether it be an SSD or HDD. This solution provides a rather interesting exterior as the entire shell is a hard ABS plastic that is then covered by a thick silicon cover to provide bounce protection should you ever drop it.

Internally, your drive it secured via screws and dense foam and is accessed via this solution's SATA interface. On the outside, this solution uses USB 3.0 supporting UASP for maximum performance. Compatibility extends to modern operating systems including Windows Vista and above along with OS X 10.6+.

The MSRP of the SilverStone SST-MMS01 comes in at $29.99 with a one-year warranty.


The packaging is quite busy with an image of the device centered and marketing following to the left.


The back side gives specifications of the enclosure in several languages.


The scope of delivery includes the USB cable, manual, and Allen wrench for securing the enclosure.


Taking a closer look at the enclosure, the top houses a simple logo with an interesting pattern molded into the plastics. The silicon sleeve is rather soft and quite easy to remove for installing your drive.


Above, we see the Type-B USB 3.0 connection.


Opening up the enclosure required the removal of six screws. The outer edge is sealed by a rubber gasket, and as mentioned in the introduction, your drive is secured with thick foam.


As I normally do, I tested the performance of the MMS01 with my 480GB Intel SSD 730. As you can see, I reached some pretty solid numbers with the SilverStone device of 425 MB/s read and 430 MB/s write.

The build quality of this enclosure is truly top notch. Starting from the top, SilverStone chose ABS plastic as it tends to have a greater impact strength along with being rather cost effective.

The only way to really get any better than this would have been using ASA plastic which tends to have better UV resistance along with the strength of ABS. Adding to this was the inclusion of brass threaded inserts that aid in securing the drive very tightly to lessen the probability of any water or dust intrusion through the rubber gasket.

On the performance side, I too was quite happy. My Intel 730 SSD performed up to expectations, reaching 430 MB/s read and write, making this an all-around solid enclosure.

In closing, for those in the market at an MSRP of $29.99, the SilverStone MMS01 is a hard storage enclosure to beat if you need the durability it offers.
