XPG GAMMIX S70 2TB Gen4 NVMe M.2 SSD Review – As Fast as They Come


The SSD Review uses PCMark 8’s Storage test suite to create testing scenarios that might be used in the typical user experience. With 10 traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games, it covers some of the most popular light to heavy workloads. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices. After an initial break-in cycle and three rounds of the testing, we are given a file score and bandwidth amount. The higher the score/bandwidth, the better the drive performs.

633MB/s for Storage Bandwidth 2.0 is a very commendable result.



For our Real World File Transfer Comparison of the world’s top M.2 NVMe SSDs, we have included several of the top Gen 4 SSDs tested to date, to include the Sabrent Rocket 4 Plus, WD Black SN850, Samsung 980 Pro, Corsair MP600, Seagate FireCuda 520, Sabrent Rocket, XPG Gammix, the Silicon Power US70 and the Sabrent Rocket Q series. This test is conducted through the transfer of data from one spot on the test drive to another to give us the truest of transfer speed results for that device.


The XPG GAMMIX S70 literally flew through our true data testing and surpassed Samsung; not an easy task whatsoever.


There is much to like about the new XPG GAMMIX S70 NVMe M.2 SSD and that starts with the fact that we see a new company named Innogrit enter the SSD landscape.  Quality SSD controller manufacturers are always a good thing.  Add to that the fact that its performance is right up there with the best of them.  In fact, the GAMMIX S70 now owns the high result to date with 7449MB/s read throughput, surpassing all others by a large margin.  As well, It went neck in neck with the WD Black SN850 in True Data Testing, placing second ahead of the Samsung 980 Pro.


There are a few things worthy of mention, however, and the first is that our initial ‘early release’ sample died after we tried to upgrade it to the newest firmware.  This shouldn’t be any concern in consumer sales whatsoever as the latest firmware would already be present on retail SSDs. . As well, as powerful as the S70 is, it runs hot and at a typical temperature of 64°C.  This was obvious in our ADATA SSD Toolbox result.

Pricing for the XPG Gammix S70 is right where we like to see it.  It is lower than both the Samsung 980 and WD_Black SN850 and right there beside the Sabrent Rocket 4 Plus.  This makes for one very tempting SSD considering all SSDs have similar heat variables and need a heatsink; XPG just includes their version for free.
