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

Perhaps one of the most admirable traits about ADATA and their gaming brand XPG throughout the years is their willingness to incorporate a wide range of SSD components in their products.  We don’t think that there is another that comes remotely close, most latching on to a certain manufacturer and establishing long lasting partnerships.  Thistrait  is the case with respect to the Gen 4 SSD that we are reviewing today, as XPG is introducing a brand new Gen4 controller from a company most had never heard of as of yet; Innogrit.

Our introduction to Innogrit goes back some time where I had met Mark Wagner, VP Innogrit WW Sales and Marketing.  He introduced us to a very early depiction of their up and coming Gen 4 controller, and in fact, its first appearance was in a CES 2020 article we had posted.  In learning a bit about Innogrit, executive lineage displayed experience through companies such as SandForce, LSI, Micron, ATI with a very strong presence of former Marvell employees.  I still remember thinking how similar their controller was in appearance to that of the SandForce SF3700 design.


The XPG GAMMIX S70 is a PCIe Gen 4×4  NVMe M.2 SSD that comes in capacities of one and two terabyte.  The S70 is situated within a flat grey aluminum heatsink which can be removed should you have a motherboard that has its own heatsink. Buyer beware though that this may void your warranty for the S70.  In our efforts to remove ADATA/XPG heatsinks previously to photograph components, we have toasted two SSDs as the glue ADATA/XPG uses does its job too well.


Performance for the GAMMIX S70 is listed at 7.4GB/s read and 6.4GB/s write which, if it reaches that, will make this SSD one of the fastest on the market. It has end-to-end data protection, LDPC to increase product longevity, uses the latest NVMe 1.4 protocol, and comes with a five-year limited warranty.  XPG claims that their heatshield cuts SSD temperatures by 30%.


Looking at the black printed circuit board, we see the Innogrit ‘Ranier’ Gen 4×4 IG5236 controller, a SKHynix DDR4 DRAM buffer chip, and two ADATA branded NAND flash memory chips which happen to be the latest Micron 3D 96-layer TLC NAND flash memory. Totally free of charge is also the ADATA SSD Toolbox which can help you maintain your SSD and can be found here:


Checking Amazon, we see the XPG GAMMIX S70 listed at $199.99 for the 1TB and $399.99 for the 2TB version which is right where we might expect it to be for a positive pricepoint.
