1. Foreword: Mechanical Revolution Jiaolong 16S equipped with YMTC PC411 512GB SSD
Not long ago, we tested a certain brand of notebook, and the PCIe 4.0 SSD on it easily exceeded 70 degrees Celsius when running under high load, resulting in a performance drop of about 20%.
For laptops, because the SSD cannot be fitted with heavy thermal armor like a desktop computer, it is easy to get out of control when carrying a high-performance PCIe 4.0 SSD.
However, the mechanical revolution Jiaolong 16S notebook we got recently is a bit unconventional, it is equipped with YMTC PC411 512 GB PCIe 4.0 SSD, without any heatsink installed, but the temperature is lower than many PCIe 4.0 SSDs equipped with heatsinks.
Most of the flash memory I/O ports of mainstream PCIe 4.0 SSDs have a speed of 1600MT/s, and an eight-channel master controller is required to achieve a read and write speed of more than 7GB/s.
For the main controller, the higher the number of channels, the higher the power consumption under high load, and the higher the temperature.
The YMTC PC411 series is equipped with NAND flash memory based on the Xtacking® 3.0 architecture, with an I/O speed of up to 2400MT/s, which is more than 50% faster than similar products on the market, and only needs four lanes to run the maximum bandwidth of PCIe 4.0 x4.
Because of this, this SSD consumes extremely little power and runs stably without the need for a heatsink, making it ideal for laptops.
Let's take the notebook apart and take a look:
This is the internal structure of Jiaolong 16S, a cooling system with dual fans and four heat pipes, two DDR5 5600MHz 8GB memory in the middle, and the network card uses AW-XB591NF, which is MediaTek MT7922.
There are two M.2 2280 ports on the left side, and the one plugged in is the Yangtze River Storage PC411 512GB SSD.

二、PC411 512GB SSD测试：读取接近7000MB/s
1、CrystalDiskMark
在CrystalDiskMark测试中,PC411 512GB的顺序读取速度达到了6920MB/s,写入速度也有5692MB/s;4K随机读取71MB/s,4K随机写入190MB/s。
In the 64GB test, the data was reduced to a certain extent, which is normal for SSDs without DRAM cache.
2、AS SSD Benchmark
The AS SSD Benchmark is too old, and it is actually not suitable for testing PCIe 4.0 SSDs.
左边是1GB容量的测试，AS SSD Benchmark总分为5977，最高顺序读取、写入速度分别为4976MB/s、2655MB/s，4K随机读写速度为62MB/s、197MB/s。
On the right is the test with a 10GB capacity with a total score of 5092. The maximum sequential read and write speeds are 5017MB/s and 2669MB/s, respectively, and the 4K random read and write speeds are 62MB/s and 197MB/s, respectively.
3、ATTO Disk Benchmark
According to the results of ATTO Disk Benchmarks, the PC411 512GB SSD can also reach a speed of 60MB/s for small file reads and writes of 0.5KB. This number is not bad, and the mainstream SSDs are basically between 20~30MB/s.
At 32K, the write speed reached 2.62GB/s and the read speed was 2.35GB/s. Starting at 128KB, the write speed is stable at around 5.4GB/s, and the read speed can reach more than 4.5GB/s.
4、3DMark
The 3DMark storage test is mainly to test the read and write performance of the game, covering the boot and loading process of Battlefield 5, Call of Duty 15: Black Ops 4, and Overwatch.
The PC411 512GB SSD has an overall score of 2048 points, with an average bandwidth of 348MB/s, and when playing mobile games, the bandwidth reaches 1873MB/s, and the average access time is 87 microseconds, which exceeds the average performance of all SSDs in the 3DMark database.
5、PCMark
The PCMark 10 Fast System Disk benchmark is designed for lightly loaded system disk applications, including JPG image file read/write/co-disk copy, Microsoft Excel, Adobe Illustrator, Adobe Photoshop light usage playback tests.
The YMTC PC411 512GB SSD scored 2288 points in the benchmark for fast system disks, with a storage bandwidth of 279MB/s and an average access time of 56 microseconds.
3. Temperature and sleep test: The maximum temperature of high-load read/write is only 53 degrees
1. Temperature test
Unlike desktops, laptops don't have enough space to install heatsinks for SSDs, such as the Yangtze River Storage PC411 512GB carried by the Mechanical Revolution Jiaolong 16S does not cover any heatsinks.
Let's test the CrystalDiskMark 64GB to see how this SSD performs.
In standby mode, the PC411 512GB temperature is around 32 degrees. In the high-load read and write state, the maximum temperature is only 53 degrees.
This is a surprising temperature performance, as most PCIe 4.0 SSDs can easily exceed 53 degrees under high loads, even with heatsinks attached.
Next, we will also do a temperature test on another Yangtze River storage PC300 512GB SSD in the notebook.
In standby mode, the temperature of the PC300 512GB is 35 degrees. Under high load, the maximum temperature is 55 degrees, which is 2 degrees higher than that of the PC411 512GB.
2. 1000 dormant wake-up tests
Normal sleep and wake-up are the basic working requirements of SSDs, and long-term and high-frequency forced sleep and wake-up of SSDs with poor compatibility often produce sleep failures.
Below, we conduct a high-intensity sleep wake-up test on the Mechanical Revolution Jiaolong 16S to see if it can be stable.
Use the built-in PWRTEST command-line tool of the Windows system, sleep for 30 seconds each time, and then forcibly wake up, a total of 1000 sleep wake-ups, all completed normally, without any errors.
This shows that YMTC PC411 512GB SSD can fully meet the needs of consumer users in terms of compatibility.
4. Simple performance test of Ryzen 7 8845HS
The Mechanical Revolution Jiaolong 16S is powered by an AMD Ryzen 7 8845HX processor and an NVIDIA RTX 4060 Laptopp.
1、CPU-Z
2、CineBench R15
In the CineBench R15 test, the Ryzen 7 8845H achieved a single-threaded score of 277cb and a multi-threaded score of 2891cb.
3、CineBench R20
In CineBench R20 testing, the Ryzen 7 8845H achieved a single-threaded score of 677cb and a multi-threaded score of 7139cb.
5. Hardware dogs
Hardware Dog is a professional hardware detection and scoring tool produced by Driver House, which is very suitable for mainstream PC players. Relying on the self-developed algorithm of fast technology, as well as authoritative test modules such as 3DMark, it can quickly, accurately and comprehensively detect the overall configuration of the PC computer, conduct a single and comprehensive test on the CPU, GPU graphics card, memory and hard disk of the computer, investigate the performance of the whole machine, and pass the global performance ranking, and know how your performance level is at a test.
The total score of the Mechanical Revolution Jiaolong 16S is 614175, surpassing 99% of users. Among them, the CPU score of the Ryzen 7 8845HS is 192715, the graphics score of the RTX 4060 Laptop is 283235, the memory score is 98245, and the hard disk score is 39980.
6. Summary: Cost-effective PCIe 4.0 SSD for OEMs
As Samsung, SK hynix, Micron and other original manufacturers began to reduce production and increase prices, more and more PC manufacturers are now starting to use YMTC SSD products.
YMTC PC411 series SSD is a high-performance, low-power PCIe 4.0 SSD product specially launched for the OEM market, which has passed the rigorous verification of PC manufacturers.
Judging from the test results, this SSD can reach a maximum read speed of 6920MB/s sequential read and 5692MB/s sequential write speed, which is also the performance of a high-end PCIe 4.0 SSD.
Of course, if you change to the 1TB/2TB model, the read speed should easily exceed 7000MB/s.
Of course, when it comes to SSDs, temperature is crucial, and high temperatures will not only reduce performance, but long-term use will also seriously affect the lifespan of the SSD.
In this regard, the performance of the Yangtze Storage PC411 512GB SSD is excellent.
We ran a high-load read and write test, and the maximum temperature of this SSD was only 53 degrees, which is the result of testing without a heatsink installed.
In contrast, not to mention PCIe 4.0 SSDs, many PCIe 3.0 SSDs are far more than 53 degrees Celsius when they are not equipped with heat sinks.
In addition, the PC411 SSD has also changed the history of poor random performance of DRAM caching schemes in the past.
It uses HMB technology, and the 4K random read speed can reach 70MB/s, which is a spike for all cache-free products, which is not far behind high-end PCIe 4.0 SSDs with DRAM cache.
By saving DRAM cache, PC411 SSDs can further reduce costs without sacrificing high performance, making them ideal for high-volume OEM markets.
