With the arrival of support for PCIe 4.0 last March for Intel processors after its launch of the eleventh generation Rocket Lake, and the proliferation of motherboards from the cheaper B550 chip that supports the interface in addition to, of course, the presence of the X570 chip, which was the first to support the interface not long ago, the interface has not become limited to support on a particular segment, which made it spread more recently.

Quick infos

  • Product name: XPG GAMMIX S70 BLADE
  • Manufacture: ADATA
  • Trade mark: XPG
  • Connecting interface: PCI-Express 4.0
  • Port: M.2 2280
  • Storage space: 2TB

Despite this, there are many criticisms or doubts, so to speak, about the feasibility of having these huge speeds in your computer and not benefiting from them for the average user, especially in games, when compared to the previous generation and also given the price, which is exorbitant, today we have the XPG GAMMIX storage unit S70 BLADE 2TB PCIe 4.0 BLADE Speeds are expected to break the 7000MB/s reading barrier, but even if you break that speed is there really a benefit from this massive performance for your device? Could this be wrong with manufacturers?

We will try to answer these questions, and by the end of the review you should have a full view of the PCIe 4.0 modules in general and the S70 BLADE module specifically, but before that let’s talk quickly about the manufacturer of this module and its journey in brief.

Not so long ago, ADATA adopted an all-company approach in the industry by launching gaming brands. The Taiwanese company’s own brand comes under the name XPG, and this may have become obvious to everyone, and the brand has proven its strength in the gaming peripherals industry in particular. Now you can own a complete XPG branded hardware, starting with the mouse, the iPad, the mouse itself, the keyboard, and finally the headphones.

But this, of course, comes next to many of the products that the company offers under the brand name, but they are internal hardware parts such as computer boxes, power supplies, random memories, even water coolers and storage units of various types, and perhaps the GAMMIX series is one of the most famous of those series under which random memories and storage units such as those fall Which is the guest of today’s review, well, let’s get out of all these introductions that are not fattening and do not sing from hunger, and let’s talk about what you, dear reader, are here for.

A Closer Look at the XPG GAMMIX S70 BLADE Storage Unit

Back in February, seven months ago, we reviewed the 1TB S70, a PCI-Express 4.0 controller that managed to achieve numbers in excess of 7000MB/s for read speeds, but it was experiencing some temperature issues and the reason for that Ineffective heatsinks even with the massive diffuser the unit came with at the time.

So, it looks like the BLADE version is almost the same as it works on the same Innogrit IG5236 microcontroller, but with a completely different heatsink, smaller and possibly more efficient? This is what you will reveal later in the tests section, but the most important part that we like to note is that with the use of this heatsink, the XPG GAMMIX S70 BLADE can work with the PS5 perfectly.

The Innogrit IG5236 is the company’s first controller that supports PCI-Express 4.0, which, as mentioned, is not new, as the same was previously used in the storage unit launched by the Taiwanese company earlier this year, so we expect the performance to be quite similar.

If you do not know, the chips are divided into three sections: SLC, MLC, and TLC before being joined by QLC by Micron. These chips differ in the capacity provided by each cell in the chip to store data, which is measured in bits, and the higher this number, the more the manufacturing cost was lower and thus this allowed companies to put more storage capacity in SSD units.

The flash chips in the XPG GAMMIX S70 BLADE are 3D NAND TLC and each chip has a capacity of 512GB, and it also makes use of the SLC cache.

The 1TB XPG Gammix S70 Blade is available for $150 or 2TB for twice the space and also $300, which is the version under review today, too expensive for a storage unit isn’t it? ADATA finally offers a five-year warranty for the S70 Blade.

XPG Gammix S70 Blade results and performance tests

Here we have a copy that comes with a size of 2 TB, and it has undergone the tests that appear before you. The testing mechanism is done by choosing the disk with the normal writing and reading tests, and these tests represent the speed of the disk in the daily operations of the average user of storing and transferring data.

The XPG GAMMIX S70 BLADE storage experience was on a PC platform for the fourth generation of Ryzen processors, the giant AMD Ryzen 9 5950X processor, and the MSI X570 Godlike motherboard from MSI. the following operation:

Test device specifications:

  • Processor: AMD Ryzen 9 5950X
  • Motherboard: MSI X570 Godlike
  • Memory: Corsair Dominator Platinum 4x8GB 3600MHz
  • Storage Disk: XPG GAMMIX S70 BLADE
  • Power Supply: DeepCool Gamer Storm DQ850-M
  • CPU Heat Sink: NZXT Kraken X73

Test conditions:

  • Using Windows 10 Pro.
  • Using the M.2 PCIe port of the X570 chip directly.
  • Activate the feature of storing fast writing commands Windows Write Cache.
  • Working on the High-Performance power system within the operating system.

The performance difference here between the two versions does not exceed 2% and it is because only the controller has been updated to a better version in this version and no more which improved the performance, if we consider that this is an improvement from the ground up, it is actually not.

This is due to the storage space difference just to be honest, as with the BLADE version we used a version that comes in a size of 2 TB while in testing the regular S70 version it came in a size of 1 TB, and if you do not know there is a difference in write speeds with different space, the more space larger storage increases write speed significantly.

This means that the S70 BLADE version that comes in a size of 1 TB would have achieved the same numbers for write speeds, as the number would be around 5550 MB / s instead of 6400 MB / s, so it should be noted so that you do not get confused at this point.


We come to the most important point here, which is the temperature, since the fundamental change in this version is the heat sink or the heat sink. In fact, the thermal performance has improved significantly with this version, with a decrease of 7 degrees, where the highest temperature of the unit was recorded with the use of the heat sink number 64. degrees Celsius, which is actually a good number for a PCI-Express 4.0 interface with such high speeds.

Is it worth it in the end?

Here we come back to the question that comes to everyone’s mind and we asked it at the beginning of the review, are all these numbers worth all these amounts? At least at this time? Well, dear reader, we will try to answer in a short and simple way, the answer is no, if you are a PC user and you use games in reality, you will not feel big differences between units that exceed the 7000 MB barrier as a unit today or PCI-Express 3.0 units whose speeds start from 1500 MB/sec.

The difference is very small and almost negligible given the huge price difference, of course, for example, in downloading games, it is only a second or two, and therefore this is hardly a real difference. For content makers and programs that rely on random readings, there may be a difference in favor of the fourth generation of the interface and significantly, but in the end, it does not justify the price difference either, and also the heat, which remains high in PCI-Express 4.0 units.

The only good thing about this version or generation of PCI-Express 4.0. In general, so far which is arguably really worth buying for use in a realistic setting, is its use with the PS5 because units below this speed or speed specified by Sony simply will not work, Thus, the presence of such units in the market is an important advantage for those who want to upgrade the PS5’s meager space while obtaining the same performance as the unit inside it, which ensures that games are loaded almost instantaneously and loading screens are reduced.

So is this unit or all the units whose speeds are skipping or revolving around the speed of this unit right for you or not, it depends on you asking yourself what do we need from it first and how will we use it.

Evaluation and final judgment

It can be said that the XPG GAMMIX S70 BLADE storage unit is just a slight update to the S70 version with more effective heatsinks, as well as its full support and compatibility with the PS5 platform, except that it is similar in everything to the version that was launched at the beginning of the year, starting with the use of the same controller and access to the same performance at the level of read and write speeds.

We liked the development that took place on the thermal front. In early 2020, XPG introduced the GAMMIX S50 storage unit, which was its first entry into the world of the fourth generation PCI-Express interface, although this unit was providing about 5000 MB, but the temperature of its control was up to 75 degrees, with the arrival of the S70 the temperature was 71, but noting that the performance increased by 2400 MB / s, with this version the temperature decreased more to record 64 degrees Celsius during pressure while maintaining the same performance.

So, it’s interesting to see what the temperatures are going to reach in the future, and maybe at some point they reach the temperatures we got used to during the third generation and become more stable.

The price of the GAMMIX S70 BLADE unit that comes in a size of 2 TB is $ 300 and half the price if you get the same space 1 TB, the price is still high but it is competitive for the units that come with the same interface, in any case if you answer the questions above during the review you can check what Whether this unit is suitable for you and your use or not.
