Mushkin carbonX USB 3.1 Gen 2 Portable SSD Review – Understanding USB Versions Key to Fast Data Transfer


As confusing as understanding different USB speeds is, it really isn’t if you understand that both your system and the storage medium need to be compatible.  Typically, all storage devices of which we are speaking will be USB 3 backward compatiblee up to just over 500MB/s as that is the standard.  If the system is newer and has a Type-C port as we described, it will most likely be a 10Gbps port and capable of the increased speed of 10Gbps which is the new standard.  It may even have Thunderbolt 3 ports which will also give you the 10Gbps speed regardless… or up to 2.8GB/s if you are connecting Tblt 3 to Tblt 3…which uses a Type-C to Type-C cable with the Superspeed designation and the number 3 branded on it. Myself, I always think USB 3 (540MB/s), 10Gbps (1050MB/s), 20Gbps (2050MB/s) or Tblt 3 (2800MB/s).  The Mushkin carbonX is 10Gbps and can transfer data up to 1050MB/s on a compatible system.

As for build and quality, we like the carbonX as it has a very attractive design, great metal exterior and even comes with a ‘sock’ or ‘bumper’ to keep from damaging the device itself should it drop.  Packaging includes both Type-A to Type-C and Type-C to Type-C cables for maximum compatibility and this device has a standard 3-year limited warranty.  We have demonstrated speeds up to 1000MB/s read and write and we might suggest you could run over this with a tank and it would still work as the built is rock solid in its design and added interior heatsink.

As for pricing, watch out as we found this portable SSD for $1971 on New Egg.  We won’t be supplying that link and even believe that Mushkin would steer you away from that sale.  Looking at Amazon right now, we see availability and pricing for the Mushkin carbonX Portable External SSD at $77.69 (250GB), $103.66 (500GB) and $145.78 for the 1TB capacity we tested today.  These prices are pretty much what we expected for a new product like this just coming to market.
