Today we are taking a look at the ADATA XPG Gammix S70 1TB SSD. The S70 is ADATA XPG’s highest performance drive, and it exists as a contemporary to other second-generation PCIe 4.0 SSDs like the Sabrent Rocket 4 Plus, WD SN850, and Samsung 980 Pro. Unique to the S70 is its choice of controller, the Innogrit IG5236 ‘Rainier’, which is not something I have encountered before. Today we will put the S70 through its paces and see how it stacks up and any growing pains the Rainier controller might experience (foreshadowing!).
ADATA XPG Gammix S70 1TB NVMe SSD
The ADATA XPG Gammix S70 1TB comes preinstalled with a grey heatsink in a M.2 2280 (80mm) form factor.
This heatsink is not easily removed by the end-user; the screws are easily removed but there is thermal adhesive essentially bonding it to the drive. Even when removed, finding out more about this drive is not easy; thanks to the shiny new Innogrit IG5236 controller, none of my normal utilities to interrogate NAND type function against this drive, and ADATA adds their own custom silkscreen to the NAND packages making visual identification impossible. Research online indicates what should be 96-layer TLC NAND packages, but I am unable to directly confirm it on my own drive.
The heatsink itself is a grey block of aluminum that does an effective job of cooling this drive. Since it is not removable this drive is not recommended if you want to utilize a heatsink built into your motherboard, but for any other scenario, the presence of this heatsink is a good thing as our thermal results will show later on.
I did not think I could remove the heatsink without damaging the drive; when I tried the PCB was beginning to bend. Instead, ADATA sent over a promo shot of the bare drive, which may or may not reflect the reality of the drive underneath. At a minimum it is conceptually accurate as far as component placement. Inside the heatsink, the SSD is double-sided. The DRAM cache, controller, and half the NAND is on the top and the other two NAND packages are on the bottom.
ADATA XPG Gammix S70 SSD Specs
The ADATA XPG Gammix S70 SSDs are in 1TB and 2TB capacities.
Thus our 1TB is the baby of the duo, with slightly slower performance specs as a result. Still, 7400 MB/s read and 5500 MB/s write are nothing to scoff at and represent top-tier PCIe 4.0 SSD performance. The extra details for the rated performance in specific tests are also interesting, though I suspect almost nobody will look past the ‘7400’ and ‘5500’ numbers. 740TBW endurance represents a decent number, edging out the rated endurance for the Sabrent Rocket 4 Plus 1TB, the WD SN850 1TB, and the Samsung 980 Pro 1TB by varying margins. Finally, the 5-year warranty is a welcome sight.
CrystalDiskInfo can give us some basic information about the SSD, and confirms we are operating at PCIe 4.0 x4 speeds using NVMe 1.4.
Test System Configuration
We are using the following configuration for this test:
- Motherboard: ASUS PRIME X570-P
- CPU: AMD Ryzen 9 5900X (12C/24T)
- RAM: 2x 16GB DDR4-3200 UDIMMs
Our testing uses the ADATA XPG Gammix S70 1TB as the boot drive for the system, installed in the M.2_1 slot on the motherboard. The drive is filled to 85% capacity with data and then some is deleted, leaving around 60% used space on the volume.
Next, we are going to get into our performance testing.
