Adata Legend 840 – Low-priced PCIe Gen 4 SSD with Innogrit controller in review

The Legend 840 is, if we disregard Adata’s gaming brand Xtreme Performance Gear (XPG), the fastest SSD available from the manufacturer so far. The SSD achieves transfer rates of up to 5000 MB/s read and 4500 MB/s write and is thus in the midfield of PCIe Gen4x4 SSDs. Adata also wants to convince with a flat heat sink, which is also suitable for installation in Sony’s PlayStation 5, and a low price. On the technical side, the installed controller is a special feature. Adata uses the IG5220 from the manufacturer Innogrit, which was only founded in China in 2016, which clearly distinguishes the Legend 840 from the majority of available SSDs. We will clarify the performance of the IG5220 and how the SSD performs compared to the already tested models in the following test with the 1 TB model.

The SSD comes in the M.2 2280 form factor, and PCIe Gen 4 is used as the interface. The maximum sequential transfer rates are 5000 MB/s for reading and 4500 MB/s for writing. Besides the 1 TB model, which is available for our review, a smaller 512 GB model is also available. However, this only writes with up to 3400 MB/s, the read speed is also 5000 MB/s.

As mentioned at the beginning, the installed controller is a special feature of the SSD. While most of the competitors mainly use controllers from Phison or Silicon Motion, Adata uses the Innogrit IG5220, also known as the Rainier Q. The controller is not a standard one. With 7.5 x 11 mm, the controller is particularly small and also very cost- and energy-saving. Micron’s latest 3D NAND TLC (Micron B47R, 176 layers) is used as the memory. We have to do without a DRAM cache. The warranty period is 5 years or up to a write performance of 650 TB, which is very good for this price range.

Scope of delivery

Adata’s Legend 840 comes in a glossy box, the dimensions of which are reminiscent of those of a 2.5″ SSD. On the front, we find information about the PCIe 4.0 interface and the capacity next to a photo of the SSD including a gray heat sink. On the back, there is information about the speed and a QR code that leads to the technical specifications.

The M.2 SSD can always be seen with a heat sink in photos, but the SSD and heat sink are separated from each other in the box. If you want to use the included heatsink, you only have to stick it on the top of the SSD, a thermal pad is already attached. Due to the low height of the heat sink and the performance, the Legend 840 is not only suitable for use in the PC, but also for the PlayStation 5.

The PCB of the Legend 840 is black and only equipped on one side. The two memory chips are located on the upper side next to the Innogrit controller. There are no components on the back, this is almost completely covered by a sticker that lists the name, part and serial number.

Test system

Performance test

For the performance test, we rely on the well-known tools AS SSD, CrystalDiskMark, ATTO Disk and HD Tune Pro. The maximum sequential read and write rates stated in the spec sheet were also determined by Adata with CrystalDiskMark (SEQ Q32T1).

Results of the performance test

In the AS SSD benchmark, the Legend 840 is almost always at the top of the list. Only in the 4K-64 THRD test does the SSD fall a bit further behind, but then it still lands in the midfield. This is also true for the benchmark score as well as the program and game tests of the copy benchmark. In return, we achieve a very good result for the ISO file.

We can confirm the manufacturer’s specifications of 5000 MB/s for sequential reading and 4500 MB/s in CrystalDiskMark. While we are only marginally above the manufacturer’s specifications with 5033.08 MB/s for reading, we are quite clearly above it with 4828.19 MB/s for writing. The result of the 4K test is also very good. All previously tested SSDs are beaten in reading and the SSD is also one of the best in writing, even if it is not enough for the top.

The SSD also makes a good impression in the other benchmarks. In the ATTO disk benchmark, the performance is slightly below that of the high-end SSDs Corsair MP600 Pro LPX and Kingston KC3000. The TeamGroup T-Force Cardea Ceramic C440, a similarly fast but more expensive model, is on par in read and is beaten in write. In HD Tune, the Adata Legend 840 achieves a very good result of 2730.8 MB/s and thus takes the lead. The lead over the Silicon Power US70 behind it is narrow, but that over the other SSDs is very clear. In terms of access times, we achieve a very good result in AS SSD, while the Legend 840 scores slightly worse in the HD Tune benchmark test.

Overall, the Adata Legend 840 leaves a mostly good, partly even very good impression in the performance test.

During testing, we reached a maximum of 70°C at a room temperature of 25°C without the included heatsink and under load. This is just within Adata’s specified operating temperatures, and there were no performance drops. The included heatsink is supposed to lower the temperature by 15%, which is quite realistic based on our experience with similar heatsinks.

Adata Legend 840 review: conclusion

The Adata Legend 840 and the Innogrit IG5220 know how to convince in the test. The SSD offers high sequential read and write rates, which are also achieved or exceeded in the performance test. The 4K performance, which is important for everyday use, is also very good, both in read and write mode. All previously tested SSDs were even beaten in CrystalDiskMark in read mode. In other benchmarks, the SSD often lands in the upper midfield. Considering the price, this result is quite good. Currently, the Legend 840 is the cheapest PCIe Gen4x4 SSD, if we disregard the few models whose transfer rates would also be possible with PCIe Gen3. This makes the SSD especially interesting for price-conscious buyers. We are curious how the prices for SSDs with Innogrit controllers will develop and also how the new competition in the controller market will affect SSD prices in general. This can only be advantageous for the customer. Besides the good performance, you get an SSD that is easy to cool, yet includes a heat sink in the scope of delivery and is also suitable for Sony’s PlayStation 5 due to the height.

There is only little that speaks against the Legend 840. Other SSDs are partly even faster, more consistent in terms of performance, but often more expensive in return. Of course, you have to decide for yourself whether you need this performance for your own use. Prospective buyers should also always keep an eye on the market, since SSD prices fluctuate strongly and faster alternatives can be available at similar prices.

The Legend 840 is, if we disregard Adata’s gaming brand Xtreme Performance Gear (XPG), the fastest SSD available from the manufacturer so far. The SSD achieves transfer rates of up to 5000 MB/s read and 4500 MB/s write and is thus in the midfield of PCIe Gen4x4 SSDs. Adata also wants to convince with a … (Weiterlesen...)
