I used one before The cooling SN750 version of the game acceleration function left a deep impression on me, so the price of this 618JD event 1799 comes with an EKWB custom heat sink version, and the speed starts with a piece.
is still black and simple packaging 3470MB/S The reading speed is really overwhelming. I can only say that SSDs are used well and I just want to use better ones. It’s said that once entering the SLR, there are three generations, DIY planting grass is also the pursuit of perfection, what we can do is the range of abilityIt's fine to enter a person that you are satisfied with and not be pitted.
WD Black SN750 EKWB customized heat sink version. This design is a bit different. The hollow transparent design makes it look best On the back instead of the front, I really don’t know what the designer thinks? It doesn't matter anyway, my focus is not here, but this 5-year warranty! Hehe! Generally, SSDs are guaranteed for three years. Everyone knows about SSDs. Generally, the warranty is that there is a problem with the pellets. If the pellets are broken, they can be replaced. This wishful thinking is good!).
This face is really attracted, it’s so beautiful! If you can bring the breathing light effect, then perfect.
The serial number is on the back. What surprises me is that the back is also a metal plate. I haven't seen it so wrapped up inside and out. Okay, just treat my hair as short and short-sighted!
The thickness of the heat sink is as high as 8mm, which is more than twice that of others. The heat dissipation should be good. Look back and see how the effect is.
There are screws visible on the side. I feel itchy when I see this, so I get to my hand There are very few people who don’t dismantle, it’s a disease! Just look at the hand itching. Everyone knows that there are very few people who don’t dismantle. , Please do not imitate the demolition. Please state in advance that if you demolition it will not count as mine!)
Thermally conductive glue is attached to the heat dissipation shell to achieve better contact with the SSD to enhance heat dissipation. The most valuable thing is that it is fixed with rare screws. Compared with the more common pull-out design on SSDs, the screw fixation is more firm canIt is not easy to loosen.
This time the main control uses its own three-core main control, and is equipped with 1G LPDDR4 particles as Cache to ensure stable reading and writing speed.
Design has Anti-voltage circuit to prevent data write-back after sudden power failure to ensure timely preservation of important data.
Two 512G SanDisk 3D 64-layer TLC particles are used on the particles to form a 1G capacity.
WD Black SN750 EKWB customized heat sink version supports game mode, which can make SThe performance of SD is further improved and the game will be accelerated to achieve faster game loading and ensure stable high-speed stability at high FPS. The improvement this time is that after the installation is complete, the default is to directly use Chinese instead of manual language changes. The all-Chinese menu and visual graphic design are still easy to understand and operate, so I won’t be long-winded here.
Performance comparison test:
The biggest advantage of having a wave of friends around is that when you need it, shouting will always lend a helping hand, when I When I wanted to see if my own WD Black SN750 EKWB custom heat sink version was worth buying, a friend immediately borrowed my disk from me. I received this Samsung 970 EVO PLUS, which was completely removed. I am embarrassed to be opened by me. I've written down this love, buddy, and I will send you a new one next time I need it.
Lined up, like Those of us who like it look so good. Have you planted grass? Anyway, I will pretend to be forced. Haha!
In the design of the heat sink, Samsung and Plextor used a single-sided design, while the data used a full package design.
Western Digital has done the best in the design of heat sink, the thickest heat sink is all-inclusive design . Samsung is the most casual in heat dissipation design, only sticking a thin copper sheet on the back. Plextor, the lowest price among the three, although not the thickest, it only does positive heat dissipation., But the heat dissipation is better than Samsung, which is really precious.
Carefully observe that the main control used by Samsung 970EVO PLUS is exactly the same as the PRO, and the anti-power-down chip is also the same , The only difference is that MLC is replaced with two TLC particles to form 1T capacity. I guess whether the difference in particles limits the performance of the performance or is it to learn INTELCore Duo routines, specially selected overclocking with K, generally shielded and sold at low prices. But no matter what, there is always one more choice. I think the expensive EVO from PRO is also good.
The Marvell88SS1093 master used by Plextor is always a bit old but cheaper, Plextor M9PeGn is the cheapest of the three and the only one with MLCThe classic design of the particles is slower but better than cheaper.
Of the three SSDs, only the Plextor M9PeGn adopts a double-sided design, with 4 pieces of 256MB The granules make up 1T capacity.
My 2080 graphics card uses the public version, because the customized version is too expensive and the performance improvement is limited, so I simply use the public version. The heat dissipation of the public version is the turbo design and it can’t take care of the heat dissipation around the motherboard.
Generally speaking, the first one The M2 interface is designed between the CPU and the graphics card. Now the CPU is basically pressed by a water-cooled radiator. The all-inclusive graphics card is a test for the heat dissipation of the SSD.
CrystalDiskMark running score test :
Use CrystalDiskMark this professional software to perform Running score. In order to facilitate the comparison of the data of each part of the explanation department, a statistical chart is made. (In order to increase legibility hereinafter referred to as brand)
The above picture is the sequential read and write test of Seq Q32T1 multi-queue and multi-thread. It can be seen that Plextor's read speed is relatively low, Western Digital It is a very small advantage and slightly faster than Samsung. In terms of writing speed, Plextor’s gap is relatively large. After all, it is understandable for the old master. Samsung has the fastest writing speed of 311MB/S more than Western Digital, and Western Digital is lower than Samsung.
4K can be a very important indicator of SSD, the system response speed in the game is loaded in a timely manner to read and write to a large extent and 4K related. In the 4K Q32T project, Plextor was surprised. 4K read and write were ranked second. It can be seen that the old master is not useless, but has its own merits. Western Digital is the best in the game after opening the game. Both reading and writing are the fastest. However, in the default mode, Samsung's performance is generally not very different, and Samsung's performance in 4K is mediocre. It can be seen that the biggest improvement of Western Digital in the game mode is the 4K read and write speed. It is recommended to use this mode.
Temperature and write pressure test:
Next, perform a high-intensity write test. Everyone knows that SSD reads are generally rareThe speed drops, but there is a buffer partition during the writing session. When this area is full, the speed drops seriously. The main reason is to look at the temperature performance and performance under extreme pressure.
In the comparison, because Western Digital is open The most obvious improvement after the game mode is 4K reading and writing, and this test is a single 500G large file writing, so in this test, Western Digital is in the default mode. The same 500G file writing is time statistics, Plextor The use time is the longest, which is exactly 9 minutes slower than the other two products. The other two disks can write twice as much data at the same time based on the speed, mainly because the Plextor drop speed is more serious. I am more surprised. Western Digital’s time is actually the shortest, while Samsung, which writes 311MB/S more than Western Digital, took 40 seconds longer.On the right, this makes me, a guy who started Western Digital, happy. In order to further dig out the reasons, statistics are made on time-to-time data.
Through the data in the above figure, we can see that Plextor started to lose speed when writing to 11G. 1300MB/S dropped to 462MB/S, and then rose back to 928.38MB/S, it should be that the fixed buffer area allocated by Plextor is fullIt started to drop to around 900MB/S, and then dropped to 484.85MB/S at 123G. The recovery mechanism worked. After all, it was the master of the old generation, so it has been ups and downs and the other two models adopt new master products. There is a big gap between Western Digital and Samsung.
Samsung and Western Digital are on par before 198G data. Both are basically stable at around 1350MB/S. Samsung's fluctuations are still smaller, but after 198G, Samsung started to drop significantly. After falling to 1206MB/S, it has been stable at around 1200MB/S, while Western Digital is very stable at 1350MB/S until the end. This is the root reason why the same 500G write to Western Digital is 40 seconds faster than Samsung. So why does Samsung drop 150MB/S at 198G? This should be related to temperature, Samsung and the heat dissipation design is too random, just a piece of copperThe temperature of the skin has exceeded 80 degrees after 198G was written to trigger the performance degradation caused by the protection mechanism.
When it comes to temperature, let’s take a look at the performance of temperature. When the initial temperature is not being written, Plextor is about 7 degrees higher than the other two disks, indicating that this old master controller has a large heat generation, and the performance of Plextor reaches the highest state when writing 10G, so the temperature ratio itsIts two disks were a lot higher, but after 19G was written, the speed began to drop drastically, so in the end it stabilized at 74 degrees.
And Samsung uses a piece of copper for heat dissipation, so it performed well at the beginning, but in the end the temperature became higher and higher, and the comparison of heat dissipation was too random, so I had to slow down after writing 198G. To lower the temperature. The best temperature performance is Western Digital, which has a lot to do with Western Digital's heat dissipation design. It can exceed 60 degrees until 500G is written, so Western Digital's performance is more stable. From the perspective of the heating of the main control, Plextor’s heating is the highest, and the heat sink is still the highest. Western Digital and Samsung are actually close, but Samsung’s heat dissipation is too poor, so I recommend adding a heat sink to Samsung’s machine friends. Prevent speed drop.
Real game performance:
Actually, whether it’s running scores or writing test tests, we can only find the performance of SSD reading and writing speed and temperature, but for most of our players The most concerned thing is the performance in the game. The answer we want is the improvement of the game. Like many players, I have to play a few games on weekdays. In order to ensure the accuracy of the data, the in-game Of Benchmarks and adopt Frap collects data. Because manual control cannot ensure that the walking path of the characters is exactly the same for the first time, and Benchmarks can do exactly the same.
Everyone generally thinks that the game graphics card is the key point. Others are not important. Indeed, from the results of the run, the 4 times are 117, 118, 118, 120, from the average frame number, there is really no big difference, but I will find the difference if I analyze it carefully.
In order to make it easier to view and make a statistical graph, the difference of balanced frames can be ignored. But the difference between the lowest frame 86 and 98 is 12 frames, and the highest frame is 15 between 145 and 160. Frame. This may not be a big deal for our ordinary players, but for professional players and those who pursue the ultimate, you can appreciate the difference brought by this.
For the loading time test of the game, in order to avoid errors, Frap is used to collect data. Everyone knows that Frap is used to see the number of frames, but the frametimes file is indeed omitted. This means each FPS The generated time. From the screenshots of the benchmarks that come with the game, you can see that it is above 100FPS at the beginning, which means that the number of frames between the first 100FPS in the Frap collection data isIt is generated during the game loading process, so add up the FPS number and then read the time from the frametimes file to get the precise time it took for the game to load.
From the loading time, you can see that Samsung’s loading time is the slowest, and Plextor’s performance is also Very good, the best is Western Digital in game mode. After opening game mode, Western DigitalSN750's 4K reading and writing has entered explosive growth, so it performs best here.
FPS data during the entire game. From the above figure, you can see the FPS data of Western Digital in the game mode. The overall performance is the best, followed by Samsung. In the default mode, Western Digital is the same as Pu Lite. The main drawback is that the lowest FPS is relatively low, but this is when the game mode is turned on.Great improvement afterwards.
After opening the game mode, Western Digital can see a huge increase in the minimum FPS, so it will not appear in the game Sudden drop of frames. Anyway, it is the function that is officially allowed, and it is still a free function, so my suggestion is to keep it on for a long time. Anyway, it does not affect the warranty. Maximizing performance is the key.
Finally talk about the experience, let's talk about it in the order of the previous comparison!
Let’s talk about the Samsung 970 EVO Plus 1T first. The overall performance is remarkable. After all, the overall quality and quality control of the big brands are there, but the big Samsung also has a larger brand premium. Therefore, it is reasonable to be relatively expensive. The main problem of the 970 EVO Plus 1T is that the 4K speed is slower. The biggest problem is the high temperature self-protection. Therefore, if you are already in use, it is recommended to buy a heat sink with a block of more than 100 pieces. It will be much more stable.
The overall performance of the Plextor M9PeGn is mediocre. The biggest problem is that the write speed is relatively serious, the heat is huge, and the heat sink is hot. But the performance of 4K is still good, the key is the price is cheap, so there is no special requirement for performance, and it is also an option for machine friends who do not pursue performance. After all, it is better than SATA interface.SSD is much stronger, it is still a MLC particle.
Western Digital's WD Black SN750 EKWB customized heat sink version gives me the biggest impression that the overall performance is stable. The excellent heat dissipation design ensures stable performance in harsh environments, especially now that the weather is getting hotter and hotter. Stable performance output instead of overheating self-protection. In addition, the 4K outbreak and FPS improvement in game mode left a deep impression on me. In game mode, the overall performance of Samsung 970 EVO Plus 1T is not output, and the game loading time is even shorter. However, the 4K reading and writing performance is lower in the default mode, but the overall performance is the best when the game mode is turned on. Therefore, it is strongly recommended to use the game mode for a long time to optimize the performance. The price is 200 yuan cheaper than Samsung, and Western Digital is an old brand that has been working on hard drives for many years. The quality is also guaranteed. The 5-year warranty is the best explanation.Therefore, it is the most satisfying choice for users who are pursuing cost performance.
Thanks to two of my friends for borrowing the disk. I wrote a few Ts over 500G writing tests, which made me painful.
Finally, everyone is welcome to discuss research together and actively express their views.
