ADATA At CES2021: XPG GAMMIX S70 PCIe 4.0 SSD Now Availableby Billy Tallis on January 12, 2021 10:30 AM EST
A year ago at CES 2020, ADATA previewed three upcoming PCIe 4.0 consumer SSDs planned for release in 2020. As with many things last year, that didn't go exactly as planned, but two of those drives have now hit the market—albeit with different model names than ADATA was using a year ago. The XPG GAMMIX S70 has now taken over as ADATA's top of the line consumer SSD, and it is starting to hit the (virtual) shelves just in time for CES 2021.
Last fall, ADATA launched the XPG GAMMIX S50 Lite as one of the first PCIe 4.0 SSDs targeting mainstream consumer usage. It uses Silicon Motion's 4-channel SM2267 controller, so it isn't aiming for the performance crown that most PCIe 4.0 models are vying for. The XPG GAMMIX S70 was also announced last fall, but only recently hit the market. It was listed on ADATA's own online store before the end of the year, but didn't hit any third-party retailers until it showed up on Newegg last week.
The GAMMIX S70 is particularly interesting because it marks the debut of a new competitor for high-end consumer SSD controllers. Innogrit was founded by storage industry veterans including a bunch of former Marvell employees. They came out of stealth mode at Flash Memory Summit 2019 with a full roadmap of client and enterprise NVMe SSD controllers, and at CES 2020 it appeared that their IG5236 "Rainier" controller had scored several design wins. The GAMMIX S70 is the first we're aware of to actually ship.

The GAMMIX S70 displaces the Phison E16-based GAMMIX S50 as ADATA's flagship consumer SSD and goes up against other second-wave PCIe gen4 SSD like the Samsung 980 PRO, WD Black SN850 and Phison E18-based drives like the Sabrent Rocket 4 Plus.
The Newegg listings for the GAMMIX S70 are at ADATA's introductory MSRP of $199.99 for the 1TB model and $399.99 for the 2TB, the same price points as the Sabrent Rocket 4 Plus and slightly cheaper than the Samsung 980 PRO or WD Black SN850. Our initial testing of the 2TB S70 has showed promising performance, but ADATA gave us a heads-up that there's a firmware update on the way so we're holding off on drawing conclusions for the moment.
With the Phison E18 and Innogrit Rainier controllers now shipping, and the in-house designs from Samsung and Western Digital, we're waiting on only Silicon Motion's SM2264 controller to round out this second wave of PCIe 4.0 NVMe SSD controllers. A year ago, ADATA had planned to make use of the SM2264 in the third PCIe 4.0 SSD they previewed, but there's no sign of it or any other SM2264 products being ready yet.

Tomatotech - Tuesday, January 12, 2021 - link8GB/s is the max bandwidth from a standard nvme x2 pcie 4.0, and at 7.4GB/s this ssd is already close to maxing it out :)
I'm not good at converting IOPs to MB/s but 650k/740k IOPs for 4kb random r/w seems to be about 3GB/s which seems impossibly good, unless I've messed that up.
James5mith - Tuesday, January 12, 2021 - linkIt's probably with 64 threads or more loading up the SSD.
I'm definitely interested in these drives, Rainer seemed like it was going to compete with the big boys back in 2020, so it will be interesting to see where it lands now.
Give me a 4TB one of these, and I have my new drive for the next 2-3years until PCIe5.0 stuff starts becoming available.
romrunning - Wednesday, January 13, 2021 - linkJust a typo, I'm sure, but PCIe 4.0 is 8GB/s (ignoring overhead) using 4 lanes, not 2.
I like the peak on the S70 getting close to it for read at 7400. I did hear of the newly-announced Kingston "Ghost Tree" SSD getting higher write at 7000, which would beat this one at 6400. I don't know what controller the Kingston one might be using, though. It was 7000 for read, so this Innogrit controller is doing better at 7400. Either way, it's all probably being measured at QD32/64, not QD1.
I still want to see a consumer release for the Alder Stream 2nd-gen Optane, like a "920p" model. That should give you some nice peaks as well but it's going to give you the performance & low latency at QD1. Price it at a decent range (maybe 980 Pro range?), and I'd buy it right away for personal use!
chadsort - Tuesday, January 12, 2021 - linkHow did it take this long to hit the market? Been using this SSD for more than a month now
