1. Foreword: YMTC launched the first first-class SSD with 3D chip architecture to break through the "impossible triangle".
Launched XTACKING 3 from YMTCAfter the new generation of NAND flash memory with 0 architecture, both manufacturers and consumers are full of praise for its performance.
The TiPro 7000, TiPlus 7100, TiPlus 5000, etc., are the first choice for a large number of DIY players, and their popularity can be seen.
The new SSD that Fast Technology wants to evaluate - YMTC PC411, it is a XTACKING 3Consumer-grade (PC OEM) products with 0 architecture.
YMTC launched this new product mainly to solve the "impossible triangle" of high performance, low power consumption and high cost performance, and provide more and better choices for PC OME customers and consumers.
The principle of YMTC Stack XTACKING architecture is to process peripheral circuits and memory units on two independent wafers, and then combine the two into one at the chip packaging stage, which achieves higher efficiency and higher density and faster speed.
Thanks to Crystal Stack XTACKING 30, NAND flash memory can easily achieve speeds up to 2400mt s, such as 8 lanes required to achieve PCIe 40 x4 upper limit (8000 mt s), now only 4 channels are needed to saturate the bus.
Of course, there are also some control commands that also occupy the bus bandwidth, so the data transfer speed that the user sees is about 7000MB s.
At the same time, the PC411 removes "redundant" DRAM and halves the number of NAND channels, maximizing potential while reducing power consumption by 25%.
With the blessing of these technologies, the YMTC PC411 SSD can achieve a theoretical maximum sequential read speed of 7000MB s and a maximum write speed of 6000MB s, easily filling PCIe 40 x4 bandwidth.
2. Appearance: Single-sided PCB design 1TB capacity only needs 2 NAND flash memory.
YMTC PC411 1TB SSD has a size of M2 2280, but according to the official documentation, there will be m2 2242 optional.
The front is printed with a product sticker, while the reverse side is empty, and it adopts a single-sided particle scheme, which can be compatible with laptops, game consoles and other devices.
The sticker part on the left of the YMTC PC411 is the position of the flash memory particles, and the right side is the main controller, which uses the DRAM-less cache-free design and supports the HBB host cache scheme.
The product label on the front is printed with the product model, capacity, serial number, rate specifications and other information.
The SSD we received has a capacity of 1TB and an interface protocol of PCIe 40 x4, supports NVME, and the working power consumption is only 5W.
Flash Particle Detail, only 2 NAND Flash packaging chips are needed to achieve a capacity of 1TB.
3. Performance test: read up to 74GB S Full Blood Play PCIe 40 x4
The test platform is as follows:
1、crystaldiskmark
In the CrystalDiskMark test, the sequential read speed of YMTC PC411 1TB SSD can reach up to 7446MB s and the write speed can reach up to 6423MB s, which has reached PCIe 40 x4 full health.
The maximum 4K random read/write is 94MB s and 317MB s, respectively.
On the right is the 64GB test, with sequential read and write speeds of 6948MB s and 6002MB s, and 4K random read/write speeds of 47MB s and 277MB s, respectively.
Switching to the actual performance mode, the results of 1GB and 64GB are also compared.
In the 1GB test, the sequential read/write speed of YMTC PC411 1TB SSD is 5053MB S and 5548MB S.
4K random speed at 22607 iops, random write speed at 69636 iops.
In the 64GB test, there is also a certain decline, and the sequential read and write speed is 4667MB s and 5515MB s.
The 4K random read speed is at 11,788 iops, and the random write performance is even better, reaching 71,497 iops.
2、atto disk benchmark
In the atto disk benchmark test results, for 0For the reading and writing of 5KB small files, the YMTC PC411 1TB SSD is quite eye-catching, with read and write speeds of 78MB S and 50 Mb respectively5MB s, which is a significant improvement over the previous 20 30MB s.
At 64kb, writes can reach 917GB s, read 5Performance at 64GB s.
Starting from 512kb can provide a minimum of 57 GB s write, 6 GB s read speed.
3. HD Tune file benchmark.
In HD Tune Pro, we chose the file benchmark test to test the SLC cache performance of the YMTC PC411 1TB SSD, and the file length of the test was 300GB.
The overall performance is very robust, both in a straight line and in a straight line, maintaining 67GB s of write (orange line.) 8GB s read (blue line).
4. 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, and can conduct a single test on the computer's processor, graphics card, memory, and hard disk to see how well your equipment performs.
Hardware Dog gave a score of 88800 points to the Yangtze River Storage PC411 1TB SSD, surpassing 99% of users, and the evaluation given is that the game reading speed is extremely fast and the performance is excellent.
4. Full disk write and temperature test: 640MB s in the slow side
1、aida64 disk benchmark linear write
In the empty disk state, the entire writing process of YMTC PC411 lasted for 36 minutes, and it can be maintained at 5The speed of about 2GB s, the back starts to fall to the outside, and the speed is 640MB s.
However, in the future, the write speed of YMTC PC411 will fluctuate to a certain extent, and the cache will be emptied every 20GB written, so that it will be repeatedly written outside and within the slow.
2. Temperature test.
In this temperature test project, we did not install a heatsink to check the stability of YMTC PC411 1TB SSD.
The standby temperature of YMTC PC411 1TB SSD was 51 degrees Celsius, and as the test progressed, the temperature reached a maximum of 71 degrees Celsius.
This performance ensures that its performance can be fully played, and it also ensures that when installed in mobile devices, game consoles and other devices, there will be no poor heat dissipation, resulting in performance degradation.
5. Summary: Although it is a non-slow solution, its performance far exceeds that of mainstream products and PCIe 4 is excavated0 x4 bandwidth all potential.
Judging from the test results, although the YMTC PC411 1TB SSD is a non-slow solution, the performance in all aspects, I have to say, is very eye-catching!
In the process of actual measurement, YMTC PC411 1TB SSD easily reached 74GB s read and write speed, which has reached PCIe 40 x4 bandwidth cap, sequential writes also have 62gb/s。
Even in moderation, its speed is not lower than 640MB s, coupled with a 4K random write speed of almost one million, this performance is far from most mainstream SSD products on the market!
In particular, its temperature control is even more eye-catching, you must know that the higher the SSD temperature, the more obvious the attenuation will be, and even the disk will drop.
However, even if the Yangtze River Storage PC411 1TB SSD is not equipped with a heat sink, the maximum temperature is only 71, which is far from the loss of the temperature wall, so there will naturally be no obvious performance loss, and the overall strength is good.
This is thanks to the blessing of YMTC's first-class 3D architecture, which can easily realize the single-sided particle design, and effectively reduce the temperature with lower power consumption, so that it can bring excellent compatibility to users, so that devices such as notebooks and game consoles with compact internal space can also achieve full blood performance.
In other words, the performance of YMTC PC411 1TB SSD is not inferior to that of products with cache solutions, and PCIe 4 is maximizedThe potential of 0 x4 is tapped.
To sum up, its main high-performance, low-power, cost-effective composition of the "impossible triangle" is not empty words, users can really feel it in use.
