There is an internet joke that those of us who got online at the beginning are the best generation as we were able to choose our username pretty easily. In thirty years time the only available email addresses will make the current XxBigBoyxX587237 online names look positively easy to remember.,That same ‘all the good stuff has been taken’ ethos applies to products too. You want your item to be unique so that it’s easy to search for. Whilst the ADATA part is easy enough to remember having been with us for twenty years now, and the XPG part is their enthusiast arm (at a guess we’d go for Xtreme Performance Gaming but we don’t know) the Gammix S70 seems like it was chosen by picking Scrabble tiles from a bag. What do you get if you multiply six by nine indeed.,However, what your drive is actually called matters little in the grand scheme of things. Drives, more than almost anything else, live and die based upon their performance and reliability. Reliability would require years more time to test than we have available, but performance is easy to test. With a PCI Express 4.0 NVMe drive we are almost guaranteed that the performance will be spectacular. There is only one way to find out.,Technical Specifications,unnamed file 2980  unnamed file 2979,Up Close,Silver text on a red background might not be the clearest thing to read, but the reality of modern shopping is that you’re not going to be picking the Gammix S70 off a shelf but getting it delivered to your door. Particularly in the current Covid times. We like the sheen on the box though. Very attractive.,unnamed file 2982
unnamed file 2983  ,Maybe we’re old fashioned but we’re a little bit wary of putting a sensitive device in plastic packaging. We know ADATA wouldn’t have done it unless it was fine, but we’ve spent too many years with anti-static straps on our wrists to want to be anywhere near combining plastic and memory in the same space.,

If we go simply with these graphs as a measure of the Gammix S70 then it is an inauspicious start. Fortunately we already know how it looks on our other graphs, so let’s move on

Anvil MB/s,We know that raw throughput isn’t necessarily reflective of real world usage, but it’s a pure test that at least gives you an indication of the performance you could expect, especially as we cover a number of block sizes here. The XPG Gammix S70 does very well, up amongst the best we’ve seen so far.,unnamed file 2992

has long been a part of the OC3D benchmark suite for drives and tests their speed across a huge range of block sizes. Whilst it has another 9 block sizes bigger than 1MB, all modern drives stay at the same speed as they do at 1MB block size. Heck most drives are already into their stride by 256KB. The Gammix S70 is very fast, only behind the Sabrent Rocket 4.,unnamed file 2995

Crystal Disk Mark 5

We never expected a drive to peak at a level beyond the Samsung 980 Pro yet here we are. It is worth paying attention to the other numbers in this graph though, especially on the read side of things. For example, the Seagate FireCuda outperforms the Gammix S70 in all but the Sequential Q32 test yet is here in 7th place. It’s why we don’t just show one result.,unnamed file 2998

Crystal Disk Mark 6

Although we’ve many versions of Crystal Disk Mark – it’s up to v8 now – and test on them all the reality is that they all chuck out very similar results. If a drive tops the CDM3 graph it’ll top the CDM7 graph etc. So just like CDM5, the CDM6 results have the S70 at the top of the table

We test the cache by using a random data file generator and just writing endless data to the disk until it’s full, whilst monitoring the transfer speed. Like so many drives before it as long as you’re writing around 10GB it’ll be blisteringly fast, but once you pass 100GB in a single write things start to slow down. Curiously the XPG actually speeds up initially before dropping down.,unnamed file 3004  unnamed file 2979


PCI Express 4.0 drives always run quite warm and the beefy heatsink on the Gammix S70 keep it in the middle of our PCIe 4.0 drive temperature charts. Clearly it’s not as effective as the heatsink on the Corsair MP600 for example.

The XPG Gammix S70 is treading a different path to a lot of the PCIe 4.0 drives we’ve reviewed recently. The majority of high speed drives have adopted the Phison controllers to bring us the blazing speeds that have dropped the jaw of everyone who has seen them. ADATA on the other hand have replaced their Gammix S50 as the flagship of their range – which is equipped with the Phison E16 controller – with the S70. The S70 is instead based upon the InnoGrit IG5236 controller. InnoGrit are a new company on the scene built from people who largely worked for the famous Marvell company, who have been part of the storage scene for decades.,The IG5236 is a 12nm PCIe Gen4 x4 controller that can support drives up to 16TB (!) in size, and is flexible enough to be able to work with MLC, TLC or QLC NAND. It has peak speeds of 7.4 GB/s read and 6.4 GB/s write. In our testing we actually got peak write speeds of 6.7 GB/s, so InnoGrit might be the first company to understate the potential of their product.,Speaking of many NAND types the XPG Gammix S70 utilises the Micron 96L TLC which we’ve seen on many drives, primarily those from Crucial. The combination of the first IG5236 controller we’ve seen in the wild and the Micron NAND allows the Gammix S70 to hit some seriously high heights. In all of our benchmarks it was up amongst the fastest drives we’ve tested in the sequential speed test. Sequential ones are always the primary focus for manufacturers as they are the quickest and thus easiest to use as a headline figure. However, the ADATA XPG drive is very good at smaller block sizes too and would make a perfect choice for an OS drive, or one that you access on a regular basis.,PCI Express 4.0 drives are famously warmer than their PCIe 3.0 counterparts and the heatsink on the Gammix S70 is clearly designed to alleviate this thermal build up. It is designed largely to take advantage of good airflow rather than simply spread the heat widely enough that it naturally gets expelled away. In our regular test system we saw it hit 73°C. Not hot enough to impact the performance but warm enough that you need to be careful when building your system to ensure it gets as much airflow as possible to keep your transfer speeds consistent instead of being thermally throttled.,The price of £369 makes the 2TB XPG Gammix S70 is a tiny expensive when compared to the Sabrent drives on the market, although cheaper than some of the more famous brands around. However, the blazing speed and consistent performance in a number of block sizes across our range of tests are enough to win it our OC3D Performance Award.,  ,Discuss the ADATA XPG Gammix S70 in our OC3D Forums.
