The ADATA XPG GAMMIX S10 (512GB) SSD Review: Entry-Level NVMe With Style
by Billy Tallis on October 25, 2017 8:30 AM ESTMixed Random Performance
Our test of mixed random reads and writes covers mixes varying from pure reads to pure writes at 10% increments. Each mix is tested for up to 1 minute or 32GB of data transferred. The test is conducted with a queue depth of 4, and is limited to a 64GB span of the drive. In between each mix, the drive is given idle time of up to one minute so that the overall duty cycle is 50%.
The ADATA XPG GAMMIX S10 doesn't quite outperform every SATA SSD on the mixed random I/O test, but it comes close. The performance is respectable for a TLC-based SSD and is a substantial improvement over the Intel 600p.
The power efficiency of the GAMMIX S10 beats most of the TLC-based NVMe SSDs, but that is the least efficient product segment in general.

The performance of the ADATA XPG GAMMIX S10 generally increases as the portion of writes in the random I/O workload grows, but the SLC cache does fill up and cause some trouble. The GAMMIX S10 is also unable to use its caching to deliver a much higher level of performance in the final phase of the test when the workload consists purely of random writes.
Mixed Sequential Performance
Our test of mixed sequential reads and writes differs from the mixed random I/O test by performing 128kB sequential accesses rather than 4kB accesses at random locations, and the sequential test is conducted at queue depth 1. The range of mixes tested is the same, and the timing and limits on data transfers are also the same as above.
The ADATA XPG GAMMIX S10 was near last place on both the sequential read and write tests, so it is no surprise to see it once again near the bottom of the chart on this mixed sequential I/O test. On average, a typical mainstream SATA SSD will offer better sequential I/O performance.
As with performance, the power efficiency of the GAMMIX S10 on the mixed sequential write test is second worst. The WD Black is significantly slower and less efficient, while the gap between the GAMMIX S10 and the Intel 600p is quite small.

As with the random mixed I/O test, the mixed sequential I/O test fills the caches of the GAMMIX S10, leading to lower and less consistent performance toward the end of the test, after a first half showing modest performance increases.

For some reason I thought the black insert was plastic, but it actually doesn't say either way. If plastic, well... You pretty much said what I was skirting around, it's all cosmetic like so many of the weird and funky heat sinks/heat spreaders you see on "enthusiast" gear. There to look cool, doesn't actually do much of anything, either because it's not really needed, the device with the heat sink doesn't actually get all that hot, or it's no more effective than a plain old simple heatsink.Wwhat - Sunday, November 12, 2017 - link
I am absolutely perplexed that anandtech doesn't specify the material of that insert. I mean that is so goddamn relevant.And I'm actually wondering what adata's comment on that insert would be. They should have asked them.
As for needed, all tests have shown a good heatsink on the M2 SSD's does indeed do a world of good. And tests have also shown that half the companies in the world that supply such, either bundled or third party, can't figure out such a simple thing as a piece of aluminium on a freaking small rectangle. I mean how complex is it? But again it's been shown that if you put a good one on it it's always noticeably beneficial.

Don't understand how one imagines a product with that seq read perf.trparky - Wednesday, October 25, 2017 - link
I went to go look at what you were talking about and my first reaction when I saw the graphs was "Ouch! WTF!". It barely matches the performance of a SATA SSD, putting it on NVMe is just a waste.r3loaded - Wednesday, October 25, 2017 - link
If your product is going to get curbstomped in performance by the 960 Evo, at least try to price it at a significant discount vs the 960 Evo.ddriver - Wednesday, October 25, 2017 - link
It is very hard to undersell samsung, they make the memory, they make the controller, they make the pcb. Vertical integration.Now imagine that you have to buy each of those components from someone else, pay profit margins on the components, then put work into making a product out of it, and sell that product with a profit margin for yourself.
It is a pointless endeavor. In a better world, they won't even bother to compete with a vertically integrated company like samsung. But in the world as it is, there are plenty of idiots who will buy this, one way or the other, either for the gimmicky but nice looking heatsink, or it will get it shoved down their throats by an OEM who has a deal with the manufacturer to bundle the product.
The negative aspect of this is that after so many years of domination, samsung will significantly cut on the purchase value of their products, because it still has tremendous lead and could let some of it melt in order to materialize as profits. Upcoming SSDs from samsung, even if a tad faster, will be disappointing compared to what we used to get in the past. Get ready for a slump of TLC and QLC, endurance and warranty period cuts.

People aren't idiots. They are just uninformed. There is a big difference. For my uninformed friends who either can't or don't want to do the research, my recommendation is always "just buy Samsung and don't worry about it". Or if they want reasonably priced but larger storage with "OK" performance then it's "just buy Crucial and don't worry about it.If you know specifically what you are looking for and know what trade offs you are willing to make there are other choices that fit certain niches. But even knowing what I wanted/needed I ended up with a 512 GB 960 EVO and a 750 GB MX300 (got on prime day last year for $139 :)).

"People aren't idiots. They are just uninformed."Tomayto, tomahto... If you make a purchase uninformed, that's idiocy right there.
IMO everyone is an idiot, including me. It is not a matter of idiots or non-idiots, at this stage of evolution we are all idiots, it's just that some are more idiotic than others. And the first step to overcoming idiocy is to acknowledge it :) The gradation of idiocy is acknowledgement of it, ignorance of it, mistaking it for something else and finally taking pride in it.

For sata the WD/Sandisk 3D SSD's seems a like a better option than the Crucials.KAlmquist - Friday, October 27, 2017 - link
A vertically integrated company like Samsung still wants to make a profit on its investments into R&D, so the fact that all of the R&D is done by one company doesn't directly help costs. It does remove some of the costs associated with developing and maintaining relationships between companies. For example, Silicon Motion has to market its products to SDD manufacturers, which is an overhead that Samsung's controller development group doesn't have. Another possible cost savings for Samsung is that it knows it's controllers will never be used with anything other than Samsung flash, so it doesn't have to develop a controller that is compatible with multiple brands of flash.
