ADATA XPG GAMMIX S70 Blade SSD Review

Review of the XPG GAMMIX S70 Blade PCIe Gen 4 NVMe SSD

Of all of the brands that are spread across the SSD industry, very few have the same level of market coverage of ADATA. With a strong memory division that has resulted in their hardware being featured in countless hardware clients in home and business, environments, as well as a long-established presence in the PC gaming community in their XPG series, there is a pretty good chance that ADATA components or accessories are somewhere near you right now. When they entered the NVMe SSD market, they did with a remarkably strong footing, with releases being separated into consumer and business needs – with virtually no compromise on wither. The XPG Gammix S70 Blade is a physically slim lined version of their popular chunky heatsink version, the Gammix S70 (non-blade), arriving with a similarly unique architecture using that Innogrit PCIe 4 controller, thin thermal plate deployment and arriving at a price point that makes a number of the Phison E18 alternatives in the market look a bit overpriced indeed. Now that the PS5 has enabled console storage and the non-Blase Gammix S70 proves too large for the task, the Adata XPG Gammix S70 Blade serves as a great choice. Add to this that many users have low expectations for how much heat will be generated in a 90/10% Read over Write systems like PS5 and even concerns over the thin Thermal plate heatsink deployment may be unwarranted. So, today I want to review the Adata XPG Gammix S70 blade and help you decide if it deserves your data.

XPG GAMMIX S70 Blade SSD Review – Quick Conclusion

Given the stronghold that Phison has over the bulk of SSDs in the current generation of NVMe, it takes a lot for a drive that chooses a different way of doing things to make its mark. The XPG Gammix S70 blade achieves this in practically every way, proving itself as an excellent example of the Innogrit Rainer controller. With performance that matches or surpasses that of its biggest rivals, yet arriving at a more affordable price point, the Gammix S70 Blade is another great gamer release from Adata in their XPG series. The slimline heatshield, although clearly designed for a particularly compact deployment, is arguably less effective than a regular heatsink (or the non-blade fat heatsink) and does possibly limit the Blade’s use in high write situations, but for traditional PC gamers and especially for PS5 SSD upgrades, the Adata XPG Gammix S70 Blade is a solid SSD that most gamers will not regret.

XPG GAMMIX S70 Blade SSD Review – Packaging

The retail box that the Gammix S70 Blade arrives in is shiny. No, that is not enough. It’s REALLY shiny, covered in holographic sheen and is oozing with gamer focus branding! The box makes a bold impact and although the majority of PCIe 4.0 SSDs in 2021/2022 are quite loud and brash in their presentation, this is a big step up still., especially given that ADATA is generally quite a ‘background’ company in most other components.

The top left of the retail box highlights a number of the drive’s key features that, although fairly standard in PCIe4 M.2 NVMes of late in most cases, still has a few stand out specs. 

Opening up this retail gives us JUST the XPG GAMMIX S70 Blade SSD. No instructions, warranty information (displayed on the rear of the box) or screws, the XPG S70 SSD and unattached slimline graphene heatshield.

If you look at the metal cover next to the SSD, you can see that the heatshield is remarkably compact. Unlike the non-blade version of the XPG S70 with its oversized heatsink, the single-use plate (with readily applied adhesive) is of course designed for much more compact deployment, such as the new PS5 SSD expansion slot activated in Summer ’21. Generally, when it comes to PCIe 4 SSDs, I would always recommend a larger and more effective heatsink for dissipating the large amount of heat the controller will be generating. However, in deployments that are going to be larger read based (which less complicated systems like PS5 will be doing) this thermal plate will likely be fine. Comparative heat testing on the PS5 vs the likes of the non-blade heatsink and the Sabrent PS5 heatsink will be coming soon on NASCompares YouTube, but even the first two test sessions with the S70 Blade on the PS5 (linked below) went perfectly well.

The heatshield is applied simply by removing the pealed panel, utilizing an adhesive topped thermal pad. It is attached INCREDIBLY firmly and is effectively single-use, in that if removed (with force) will tear the thermal pad away.

Even a casual glance at the XPG Blade and heatshield next to the non-blade fat heatsink gives you some idea of just how thin that metal panel is. The non-blade heatsink even manages to raise the height of the SSD M.2 connector notably too.

Applying the XPG S70 Blade heatshield to the SSD, although making the drive arguably cooler looking, definitely shows how little surface area and density of heat dissipation are going to be possible. I would be concerned about the Blade in deployment in an area that has limited/zero airflow, as that heatshield is only going to be able to offload a small amount of heat from the SSD controller compared with the bigger version. Again, less of a concern in heavy read activity though.

So, what about in PS5 deployment? For those of you who have been considering the ADATA XPG GAMMIX S70 Blade for installation in the PS5 SSD expansion slot to increase storage, I am pleased to confirm that this SSD is 100% supported by the system (currently in software beta, but the Gammix S70 Blade will definitely be on the compatibility list of the full software update release. However, the physical installation needs highlighting.

Comparing it against the non-Blade, you can see why many have been looking at the XPG Gammix S70 Blade for PS5 deployment.

BLADE Version

Non-BLADE Version

The XPG GAMMIX S70 Blade takes up considerably less space in the PS5 storage expansion slot, leaving more room to allow air to flow over the heatsink. The non-Blade included heatsink, being considerably larger, not only fills the m.2 slot considerably more, but it also presents a new problem. Namely that the Gammix S70 NON-BLADE is too large and prevents a user from installing the M.2 bay cover. On the one hand, the fat heatsink is in the direct line of airflow through the PS5 system, which means it will get getting air passing on/through the fat-heatsink. However, this also means that it is partially obstructing the airflow inside the PS5 towards other components. The PS5 utilizes negative airflow (pulling air through one set of vents and push it through the net) and it is unknown whether an M.2 in this slot uncovered AND protruding out into the air path would negatively affect the system as a whole. Hence why many users would opt for the Blade version as a matter of overall precaution.

BLADE Version

Non-BLADE Version

Installing the ADATA Gammix S70 Blade in the PS5 M.2 SSD bay at startup allows you to run a benchmark on the drive. Oddly, despite the high performance of this SSD, the PS5 rated the drive at over the recommended minimum of 5,500MB/s in its initial benchmark. Below is how the Adata XPG Gammix S70 Blade and non-Blade version compared when the PS5 Benchmarked them both:

PS5 Benchmark – 6,009MB/s

BLADE Version

PS5 Benchmark – 6,235MB/s

Non-BLADE Version

The fact that ADATA includes the heatsink with your purchase of the XPG GAMMIX S70 Blade will always be attractive to buyers who want hassle from installation, as well as doing so at no additional cost and STILL arriving at a lower price point than many competitors is inarguably appealing. So that is the physical design of the XPG GAMMIX S70 Blade SSD. But what about the hardware components themselves? Does the XPG GAMMIX S70 Blade cut the mustard in terms of current generation hardware and protocols? Let’s find out.

ADATA XPG GAMMIX S70 Blade SSD Review – PS5 Benchmark

To put the ADATA XPG GAMMIX S70 Blade SSD PS5 Performance Benchmark into a little perspective, here is how it compares against the Addlink A95, Adata XPG Gammix S70, Sabrent Rocket 4 Plus and Gigabyte Aorus 7000s – four SSDs that are all PS5 supported and VERY similar architecture very little difference between the others in this tier, it is a solid benchmark.

Addlink A95 PS5 Benchmark – 6556MB/s XPG GAMMIX S70 PS5 Benchmark – 6235MB/s
Sabrent Rocket 4 Plus – 6557MB/s Gigabyte Aorus 7000s PS5 Benchmark6557MB/s

Full PS5 Testing of the Adata XPG Gammix S70 is all available as a playlist over on the NASCompares YouTube channel. But for now, let’s carry on with looking at the hardware of the A90S70 Blade, how it conventionally benchmarks and how it compares with currently favourite PS5 SSDs like the WD Black and Seagate Firecuda 530,

XPG GAMMIX S70 Blade SSD Review – Hardware Specifications

As you might expect from an M.2 NVMe SSD that boldly promises performance of over 7,000MB/s sequential read (ie BIG data), the hardware specifications and architecture of the XPG GAMMIX S70 Blade are quite modern. Indeed, for all the big talk of the Seagate Firecuda 530 hardware (still currently the ‘score to beat’ PCIE Gen4 m.2 NVMe right now) being top tier, the XPG GAMMIX S70 Blade is pretty darn similar on the spec sheet! Below is how it looks:

ADATA GAMMIX S70 Blade

500GB –  $99, 1TB – $199, 2TB – $389

PCIe Generation PCIe Gen 4
NVMe Rev NVMe 1.4
NAND 3D TLC Micron 176L
Capacity 500GB – 1TB – 2TB
Controller Innogrit IG5236
Warranty 5yr

I know a lot of the above will seem needlessly technical, so below we can bring the most important considerations into sharper focus.

Hardware Focus of the XPG GAMMIX S70 Blade SSD Series

The first big, BIG thing to remember here is the controller, that Innogrit RainIer IG5236. An SSD is much like a microcosm version of a whole computer. The Controller is equivalent to the CPU, and although Inoogrit has produced several high profile SSD controllers in the last few years, this is their first PCIe 4.0 controller. This is a particularly big deal when most reports and measurements seemingly indicate that the Innogrit IG2536 is higher in performance than the Phison E18 controller used by most other recent PCIe 4 M.2 NVMe SSD, as well as because some long-running storage brands like Samsung and WD have most of their development and hardware engineering ‘in-house’ and use their own branded controllers. Indeed, the XPG Gammix S70 Blade is one of very, VERY few SSDs that are using this controller in the home/prosumer gamer sector.

Earlier in 2021, CDRLabs ran performance testing with CrystalDisk on the Gammix S70 Blade SSD, comparing against a Phison E18 SSD of similar architecture (176L 3D TLC NAND, DDR4 RAM, NVMe 1.4, etc) and largely surpassed it by hundreds of Megabytes in Sequential Read and Write performance. So these results tend to back up the increased performance benchmarks that ADATA provide on the XPG S70 Blade. This is further improved with a recent software/firmware update for this drive released in August 2021 that further improved the write performance.

The NAND on the XPG GAMMIX S70 Blade is where the data lives! SSDs (as you no doubt know) do not use moving parts as found in traditional hard drives and instead uses cells that are charged and data is read/written to them in this process. The quality of the NAND and the layers used will make a big difference to the durability and performance of an SSD and the XPG GAMMIX S70 Blade arrives with the current highest layer NAND in the industry at this tier right now (originally premiered in the Seagate Firecuda 530), it is bigger than most, arriving at 176 Layers of 3D TLC NAND. Although the majority of modern PCIe M.2 SSD use 3D TLC NAND (avoid QLC NAND like the PLAGUE btw!), most are still at 128L or 96L layers or so, so this is a big jump up for the XPG GAMMIX S70 Blade SSD. Although detailed information on the NAND used is not readily available online, we observed that the XPG GAMMIX S70 Blade featured FOUR blocks of ADATA NAND modules (256GB each), which really pushes the performance up!

Much like the Controller on the XPG GAMMIX S70 Blade being the ‘CPU’, it also has an area of memory. The XPG GAMMIX S70 Blade SSD uses DDR4 memory on board and this in conjunction with the SSD controller provides a massive body of data handling resources for getting your data moving through the SSD and out of the m.2 NVMe PCIe 4 interface. The amount of memory scales in conjunction with the 1TB or 2TB SSD you use, with 2GB of DDR4 at the on the 2TB tier, 1GB DDR4 on the 1TB, etc.

As mentioned, all available capacities of the XPG GAMMIX S70 Blade arrive at 2280 in length. This is quite normal for the 1TB and 2TB versions, but the fact that the 2TB can arrive on single-sided SSD boards is very impressive. Physical storage NAND is distributed evenly in order to space out the storage and allow even cooling, NAND wear and performance.

Finally, there is the M.2 NVMe connection. Not all m.2 SSDs are created equal and although M.2 SATA and M.2 NVMe look similar, they provide massively different performance and connectivity. However, the XPG GAMMIX S70 Blade takes it one step further, by using a newer generation of PCIe Connectivity. In short, M.2 NVMe SSDs are connected to the host PC/Console system via PCIe protocol (think of those slots that you almost always use for your graphics cards, but a much, MUCH smaller connector). These allow much larger bandwidth (ie maximum speed) for the connected storage media, Much like regular PCIe slots, they have different versions (i.E PCIe Gen 1, 2, 3, 4, etc) and also a multiplying factor (x1, x2, x4, etc). Up until around 18 months ago, the best M.2 NVMes were M.2 PCIe Gen 3×4 (so a maximum 4,000MB/s possible). However, never generation SSD like the XPG GAMMIX S70 Blade use PCIe Gen 4×4 (a potential 8,000MB/s possible) and it is only now that SSD controllers and NAND production has reached a point where it can catch up and fully saturate (i.e fill) this connection.

Overall, you really cannot fault the hardware inside/onboard the XPG GAMMIX S70 Blade, as it is still (2-3 months after release) higher performing in sequential Read and Write than many other M.2 NVMe PCIe 4 SSDs released in that time. Before we go into the full testing, however, it is worth taking a moment to look closely at the reported performance benchmarks of the XPG GAMMIX S70 Blade, as although the performance seems stellar, there are areas such as IOPS and endurance when compared with its main rivals that are worth taking into consideration.

XPG GAMMIX S70 Blade SSD Review – Official Stats First

Before we conduct our own testing on this SSD, Let’s take a closer look at the reported specifications and benchmarks first. The XPG GAMMIX S70 Blade SSD arrives in multiple capacities (below). The Prices currently are a little inconsistent (with each higher capacity tier actually having a higher price per GB – quite unusual) likely due to the hardware shortages, the Pandemic, Chia has affected SSD availability in the last 12 months and most recently the announcement that PS5 supports this SSD and it has increased the current price of both models around 10-20%!. Below is a breakdown of how each competitor drive and the XPG GAMMIX S70 Blade SSD compare:

DWPD N/A 0.7DWPD N/A

There are clear throughput improvements as you rise through the capacity tiers (not unusual), as does the rated 4K IOPS. Though one area worth focusing on a little is that TBW (terabytes Written) and DWPD (Drive writes per day), as this drive is rated a pinch higher than the Samsung 980 Pro and WD Black SN850 in terms of NAND lifespan on daily writes, likely down to that controller and 176 Layer 3D TLC NAND used, rather than the 96L or 128L used by those used by competitors. This is an important point because the brand has significantly less ‘end user’ recognition in-home/business SSD media than the likes of Samsung, WD and Seagate and people will want to know they are going to get a product from a brand that they have heard of.

However, despite the use of the Innogrit Rainier IG5236 controller and 176 layer NAND, the reported IOPS on each capacity is actually a noticeable degree lower (for the most part) than those reported by their competitors. Indeed, the XPG GAMMIX S70 Blade is one of the few SSD/Memory focused brands with a PCIe 4.0 SSD that does not cross into the reported 1 Million IOPS mark, maxing out at 740k. This is still very impressive anyway, but it does make me wonder where the disparity stems from. Indeed, when you look at the bulk of PCIe 4×4 M.2 NVMe 1.4 SSD that feature the E18 controller and 96L (or higher) on board, it really only leaves about 4 other SSDs in the market today that this can be compared against. The Sabrent Rocket 4 Plus, the MSI Spatium M480, the Gigabyte Aorus 7000s and (current leader) the Seagate Firecuda 530. Of those, the only one that seemingly ‘out specs’ the XPG GAMMIX S70 Blade is the Seagate Firecuda 530. However, the XPG GAMMIX S70 Blade SSD has been available in the market for longer and has certainly embedded itself in the minds and budget’s of PC/PS5 gamers who think the Firecuda 530 is too expensive and the others are less impress – it makes a very appealing middle ground. Below is how these drives compare in terms of throughput and IOPS:

Yes, that is a LONG table, but you can immediately see that the Seagate Firecuda 530 raises the stakes on all of the key specifications. Additionally, the WD Black arriving at a better price point, higher IOPS in most tiers and the fact it does this whilst still hitting that 7,000MB/s certainly gives pause for thought. However, for many, the additional cost for higher durability they may never need, peak performance their core system will not reach and IOPS rating that their larger file handling will never utilize will mean that holding out for the Firecuda or WD Black SN850 is not in their interest. Both SSDs (on paper at this stage!) are fantastic examples of where consumer and prosumer SSDs are evolving towards. Remember that you can get 1TB of XPG GAMMIX S70 Blade for the same price as 500GB of the Firecuda 530 – which given the similarity of that performance means that you are getting incredible value! Additionally, it is worth noting that although IOPS on the XPG Gammix S70 Blade were lower than those reported on the WD Black SN850 and Seagate Firecuda 530 were higher, the Sequential Read and Write for the XPG Gammix S70 Blade were higher on both versus the WD Black and even a pinch higher on Read vs the Firecuda 530 – which is a particularly impressive vote of confidence in the Innogrit controller and the XPG GAMMIX S70 SSD. Let’s get the XPG GAMMIX S70 Blade on the test machine!

Testing the XPG GAMMIX S70 Blade m.2 PCIE4 NVMe SSD

The XPG GAMMIX S70 Blade was selected for this test and it was tested using multiple benchmark tools, from a cold boot, in the 2nd storage slot (i.e not the OS drive). Each test was conducted three times (full details of this are shown in the YouTube Review of the XPG GAMMIX S70 Blade over on NASCompares):

Test Machine:

  • Windows 10 Pro Desktop System
  • Intel i5 11400 Rocket Lake – 6-Core 2.6/4.4Ghz
  • 16GB DDR4 2666MHz Memory
  • Intel B560M mATX Motherboard
  • OS Storage, Seagate Firecuda 120 SSD
  • Test SSD connected to Secondary PCIe Gen 4 M.2 Slot

Using CrystalDisk, we got a good measure of the drive and verified that this PCIe Gen 4 x4 SSD was indeed using the 4×4 lane. Additionally, the temp averaged out a little higher in idle than most previously tested SSD, HOWEVER, the ADATA Gammix S70 Blade heatsink kept the drive at a consistent temp of late 40’s for most of the tests and did an incredible job of maintaining a working temp without spiralling too high between each one being conducted.

The first tests were conducted using the ATTO disk benchmark software. The first was a 256MB test file size and below is a breakdown of the transfer rates and IOPS. The 2nd Test was a 1GB test file and finally, the last test was with a 4GB test file. The system was given 1-minute cool downtime between tests, no screen recording software was used (remove overhead) and a heatsink was used throughout (no reboots)

ATTO Disk Benchmark Test #1

256MB File PEAK Read Throughput  = 6.50GB/s

256MB File PEAK Write Throughput =5.85GB/s

 


 

ATTO Disk Benchmark Test #2

1GB File PEAK Read Throughput  = 6.56GB/s

1GB File PEAK Write Throughput = 5.84GB/s

 


 

ATTO Disk Benchmark Test #3

4GB File PEAK Read Throughput  = 6.50GB/s

4GB File PEAK Write Throughput = 5.89GB/s

 


 

Next, although the ATTO tests were quite good, but not what I would have hoped from this SSD, so I moved on to the Crystal Disk Mark testing to see how well it would handle our lasts barrage of tests. The first test was the 1GB file testing, which measured both sequential and random, as well as the read and write IOPS. Test were conducted on a 1GB, 4GB and 16GB Test File. I also included a mixed 70/30 read and write task to give a little bit more of a realistic balanced workload. These tests were conducted with 1-minute cooling break in between

CRYSTALDISK MARK 1GB TEST


CRYSTALDISK MARK 4GB TEST


CRYSTALDISK MARK 16GB TEST

 

Next, I switched to AS SSD benchmark. A much more thorough test through, I used 1GB, 3GB and 5GB test files. Each test includes throughput benchmarks and IOPS that are respective to the larger file sizes (important, if you are reading this and trying to compare against the reported 4K IOPS from the manufacturer).

AS SSD Benchmark Test #1

 


AS SSD Benchmark Test #2

 


AS SSD Benchmark Test #3

Ordinarily, I would introduce tests like BlackMagic and AJA into the mix here, but even a short burst of testing on an NVMe like this would over saturate the cache memory on board. Nevertheless, in the short term we still could ascertain the reported performance on 1GB, 4GB and 16GB file testing was:

1GB AJA File Test Results (Peak) = 5797MB/s Read & 5063MB/s Write

4GB AJA File Test Results (Peak) = 5874MB/s Read & 5218MB/s Write

16GB AJA File Test Results (Peak) = 5920MB/s Read & 5234MB/s Write

Throughout the testing, the XPS GAMMMIX S70 Blade SSD started at a slightly higher than average temp, but maintained a good operational temperature throughout the whole testing:

Overall, the XPG GAMMIX S70 Blade was certainly able to provide some solid performance, as well as potentially exceed the test figures here on a more powerful machine. Given the reported Read and Write statistics that the brand has stated publically, I think there is enough evidence here to back up those claims. IOPs were a little lower than I expected, but again, we were testing very large file types, so this would have to be taken in context.

XPG GAMMIX S70 Blade SSD Review – Conclusion

Given the stronghold that Phison has over the bulk of SSDs in the current generation of NVMe, it takes a lot for a drive that chooses a different way of doing things to make its mark. The XPG Gammix S70 blade achieves this in practically every way, proving itself as an excellent example of the Innogrit Rainer controller. With performance that matches or surpasses that of its biggest rivals, yet arriving at a more affordable price point, the Gammix S70 Blade is another great gamer release from Adata in their XPG series. The slimline heatshield, although clearly designed for a particularly compact deployment, is arguably less effective than a regular heatsink (or the non-blade fat heatsink) and does possibly limit the Blade’s use in high write situations, but for traditional PC gamers and especially for PS5 SSD upgrades, the Adata XPG Gammix S70 Blade is a solid SSD that most gamers will not regret.

PROs of the XPG GAMMIX S70 Blade CONs of the XPG GAMMIX S70 Blade
Great to see non-Phison E18 SSDs in the market

176L 3D TLC NAND is a big plus over the current 96L non-Blade Version

Excellent Value (Especially With the Reported Performance)

PS5 Compatibility Confirmed

Unparalleled Compact Deployment

Low Heat Temp Recordings in Read Activity

August ’21 Update Increased Performance Further

The heatshield is very limited in its deployment vs traditional ‘fat’ heatsinks

PS5 Has an oddly resistant Benchmark vs Phison E18 SSDs (still unknown why – largely academic in its impact though)
