Mushkin Gamma Gen 4 2TB SSD Review – Phison E18 SSD Controller at the Helm


SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. For our Mushkin Enhanced Gamma Gen 4 NVMe SSD testing today, our goal is to test in a system that has been optimized with our SSD Optimization Guide. In this instance, the CPU C-States, Enhanced Intel SpeedStep Technology (EIST) and Intel Speedshift (P-States) have not been disabled. As you will see below, the system is also bumped to 5.3GHz with memory at full speed in its XMP 2 profile.

The components of this Test Bench are detailed below.  All hardware is linked for purchase and product sales may be reached by a simple click on the individual item. As well, the title is linked back to the individual build article where performance testing can be validated. Clicking on the Title below will bring you to our complete report on this new Gen 4 PC system.

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, TxBench, PCMark 8, PCMark 10, as well as true data testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.


Crystal DiskInfo validates that we are running in Gen 4×4 mode and, as well, that we are running in the NVMe 1.4 protocol


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


ATTO provides solid results as can be seen by the steady progression of performance as sample sizes progress.  High performance results are just a bit under spec at 6.65GB/s read and 6.3GB/s write.

    How long can I write at the write speed of 6.8GB/s? Until the SSD is fully written or just a few seconds ?

      I have this feeling that you already know the answer to that and it would be one heck of a challenge actually ever achieving a steady 6.8GB/s transfer write speed. This is the flash industry theme, however, where the SSD is advertised at its maximum potential and not steady state or speeds that will occur over linger file transfers. I would guess that this is because those speeds are so greatly affected by the data sample they are moving, whether it be media or much smaller OS files for instance. We could relate this to how vehicles advertise their high mileage couldn’t we? Thanks for jumping in!
