1. Introduction: YMTC creates high-reliability, ultra-low-temperature OEM SSD products
There is a sentence to describe YMTC SSD that is particularly suitable - real gold is not afraid of fire!
In 2021, there was a brief boom in hard disk mining, where a large number of users used SSDs to mine a virtual currency called CHIA, which can destroy an SSD with a write life of 300TBW within 40 days.
YMTC is the favorite SSD brand among miners, because a large number of Zhitai PC005 Active 512GB SSDs still have a fairly high health after writing to 400TBW or even 500TBW, far exceeding their established write life of 320TBW.
The quality of YMTC original 3D NAND flash memory can be seen!
In addition to its superior reliability, NAND based on the Xtacking 3.0 architecture is also the industry's first flash memory chip with I/O speeds of 2400MT/s.
At present, many PCIe 4.0 SSDs have a flash memory I/O interface speed of 1600MT/s, and if you want to run to a read and write speed of more than 7000MB/s, you need to be equipped with an 8-channel main controller, which is also the most important reason for the high temperature of high-end PCIe 4.0 SSDs.
With an SSD with YMTC I/O speed of 2400MT/s flash memory, it can easily run to 7400MB/s with only a 4-channel main control chip.
For the main controller, the higher the number of channels, the higher the power consumption under high load, so SSD products equipped with YMTC's next-generation Xtacking 3.0 architecture NAND flash memory can achieve flagship-level performance at extremely low temperature and power consumption.
Recently, we got the Mechanical Revolution Aurora Pro notebook, equipped with YMTC PC411 1TB PCIe 4.0 SSD, let's take a look at its disk performance.
This is the internal structure of Jiaolong 16S, a cooling system with dual fans and five heat pipes, two DDR5 4800MHz 8GB memory in the middle, and the network card is Intel AX201 Wi-Fi 6.
There are two M.2 2280 ports on the right side, and the upper one is plugged into the Yangtze River Storage PC411 1TB SSD, without a heatsink installed.

二、PC411 1TB SSD测试：顺序读取可达7118MB/s
1、CrystalDiskMark
在CrystalDiskMark测试中,PC411 1TB的顺序读取速度达到了7118MB/s,写入速度也有6372MB/s;4K随机读取60MB/s,4K随机写入139MB/s。
In the 64GB test, the read and write speeds can still reach 6923MB/s and 5976MB/s, and the 4K random performance is reduced to a certain extent, which is normal for SSDs without DRAM cache.
2、AS SSD Benchmark
The AS SSD Benchmark hasn't been updated in years, and it's not a good test for high-performance PCIe 4.0 SSDs.
3、ATTO Disk Benchmark
According to the results of ATTO Disk Benchmarks, the PC411 1TB SSD can reach a speed of 37MB/s for small file reads and writes of 0.5KB.
At 32K, the write speed reached 2.1GB/s and the read speed was 2.03GB/s. Starting at 256KB, the write speed is stable at around 5.8GB/s, and the read speed can reach more than 6.5GB/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 1TB SSD has an overall score of 2360 points, an average bandwidth of 403MB/s, and an average access time of 76 microseconds for mobile gaming, which exceeds the average 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.
YMTC PC411 1TB SSD scored 2182 points in the benchmark for fast system disks, with a storage bandwidth of 267MB/s and an average access time of 59 microseconds.
3. Temperature and sleep test: the maximum read/write degree for high load is only 51 degrees
1. Temperature test
The temperature performance of the SSD is very important for a notebook.
For example, we have tested a certain brand of notebook in the past, and the PCIe 4.0 SSD carried by it easily exceeds 70 degrees Celsius when running under high load, resulting in a decrease in performance of about 20%.
The Yangtze River Storage PC411 1TB SSD equipped with the Mechanical Revolution Aurora Pro does not cover any heatsink, so let's test the CrystalDiskMark 64GB to see the temperature performance of this SSD.
In standby mode, the PC411 1TB temperature is around 29 degrees. In the high-load read/write state, the maximum temperature is only 51 degrees.
That's a lot cooler than most PCIe 4.0 SSDs with heatsinks installed.
2. Dormancy test
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 1TB SSD can fully meet the needs of consumer users in terms of compatibility.
4. Summary: PCIe 4.0 SSD is very suitable for high-performance PCs and mini hosts
With flagship-level performance, superior reliability, and no need for heatsinks, YMTC PC411 PCIe 4.0 SSD can be said to be the best storage product tailored for OEMs.
Judging from the test results, the PC411 1TB can achieve a sequential read speed of 7118MB/s and a sequential write speed of more than 6300MB/s, which is comparable to the performance of a high-end PCIe 4.0 SSD.
However, the actual performance of SSD is closely related to the whole machine platform, and the i5-13450H carried by the mechanical revolution Aurora Pro can only be regarded as an entry-level mid-range processor product, if it is a higher-end i9-14900HX processor, PC411 1TB should be able to run better.
Considering that the laptop will sleep and wake up frequently, we also did 1000 sleep wake-up tests, and the YMTC PC411 1TB PCIe 4.0 SSD also successfully completed all the tests without any errors.
Of course, the most surprising thing is its temperature performance.
In fact, when performing high-load read and write, the maximum temperature of PC411 1TB SSD is only 51 degrees, you must know that it does not cover any heatsink at all.
It's also the high-end PCIe 4.0 SSD we've seen so far.
This temperature performance is also ideal for OEM PCs such as laptops or mini PCs that do not have enough space to install SSD heatsinks.
