Lexar NM1090 PCIe5.0 Gen5x4 NVMe SSD experience: 12000MB/s ultra-high-speed reading, RGB cooling vest is a perfect match

With the advancement of the times, consumers have higher and higher requirements for the performance and speed of solid-state drives. Currently, the nominal read speed of mainstream flagship solid-state is 7400MB/s, but the PCIe5.0 solid-state has a read speed of up to 12000MB/s. It's still rare, so when we got this Lexar NM1090 PCIe5.0 Gen5x4 NVMe solid-state drive, we couldn't help but sigh that the PCIe5.0 solid-state slot on the motherboard finally had a use.

On June 12th, the Lexar NM1090 solid-state drive was officially launched for sale. The price starts at 1,599 yuan. It comes with a cooling vest, cooling fan and RGB lighting effects. How is the performance of such a fully equipped PICe5.0 solid-state drive? Let’s take a look.

Appearance design

This time I got the 1TB version. The packaging box adopts classic black and gold color scheme, highlighting the flagship positioning. There is a picture of the actual product printed on the front of the box. The product model and capacity are marked or lined in dark gold, and the swirl pattern decoration on the back of the hard drive represents its built-in cooling fan with RGB. The package includes the product plastic sleeve, hard drive body, M.2 slot fixing screws and a simple instruction manual. Take out the Lexar NM1090 solid-state drive body. Compared with the picture on the packaging box, there is an extra 5V three-pin ARGB connection line in the heat dissipation vest. The cooling vest is made of black all-metal material, with four symmetrical grilles on the front and a circular RGB cooling fan in the middle. The weight is 72.5g, and the measurements are 84*24*17.35mm. Looking from the side, you can see that the entire cooling fin module is very thick, with four screws fixing it on the side, and there is a gray-white thermally conductive silicone sheet between the cooling module and the solid state drive. There is a label with product information printed on the bottom of the cooling vest. There is also a thermally conductive silicone sheet between the bottom of the casing and the solid state drive. In addition to the thickness of the casing metal itself, it is actually installed on the motherboard. If you want a perfect match, no screws are required. For the buckle fixing structure, you need to remove the heat-conducting silicone sheet that comes with the motherboard's M.2 slot to buckle it. Tearing down the outer heat dissipation vest, the internal hard drive is indeed affixed with thermal conductive silicone sheets on both sides, and the solid state drive body is also affixed with a heat dissipation sticker with heat conduction function. The overall heat dissipation material is quite sufficient. The RGB fan of the Lexar NM1090 solid-state drive will work on its own after you put it on the computer and emit soft and smooth RGB lighting effects. With other lighting effects, the interior of the chassis can be decorated with more atmosphere, and the solid-state drive also gets better heat dissipation protection.

Theoretical performance

According to official product parameter information, the 1TB version of Lexar NM1090 PCIe5.0 Gen5x4 NVMe SSD can reach a maximum sequential read speed of 11500MB/s and a sequential write speed of 9000MB/s, while the 2TB capacity version can achieve It can achieve full-speed sequential reading of 12,000MB/s, random reading and writing speeds of 1,300KIOPS and 1,400KIOPS respectively, a nominal total written data volume of 700TBW, 4GB independent cache capacity, and a 5-year limited warranty. Before the test, let me explain the test platform as usual. The processor is Intel Core i7-14700K, the motherboard type is Z790 D5, and the memory type is DDR5 7600MHz 16GB*2 strips. We installed the solid state in the first hard disk position under the CPU. All the following tests are based on this platform and the results are for reference only. First, the theoretical read and write scores were run through the test software CrystalDiskMark. When the disk was empty, its sequential read speed reached more than 11700MB/s, and its write speed reached more than 9600MB/s. The 4K speed performance was also very good. , it seems that the official deliberately lowered the peak speed. Such reading and writing performance must be among the best among current solid-state drives. Following the 25% mildly dirty disk running score, the sequential read and write speed of the Lexar NM1090 solid-state drive 1TB version is still outstanding, and even the read and write performance of the 4K Q32T16 is even better. After further running it with 50% filling, the sequential read and write speed dropped to half the level, but it is still an excellent performance in PCIe4.0x4 solid state. The last is the performance when the disk is 75% heavily dirty. The overall performance is not much different from the performance when the disk is 50% dirty, except that the read speed of 4K Q1T1 drops slightly more. It seems that if you want to maintain the officially announced full-speed reading and writing performance, you have to choose a version with a larger capacity. Let’s take a look at the performance in terms of 4K throughput. The 1TB version of the Lexar NM1090 SSD ran out random read and write results of 1355KIOPS and 1424KIOPS respectively, which is in line with the official theoretical performance and can be regarded as the best among current NVMe SSDs. The best. Seven reads and three writes refers to a mixed read and write test of seven reads and three writes at 4096 bytes under Q1T1. Generally speaking, when you start the software from the hard disk or open the game loading or map loading At that time, most of them used ultra-small files of about 4KiB, which were both read and written. Read operations accounted for a larger proportion, and the two working states of the hard disk were carried out at the same time, so this test is very suitable for consumption. users’ daily usage scenarios. This test combination can be called up in the original CDM, and the final test result of the 1TB version of Lexar NM1090 solid-state drive is 128MB/s in seven reads and three writes, which is quite good. After all, in the historical solid-state drive test data, the performance of the 1TB version of the flagship solid-state drive is generally around 100MB/s-120MB/s. Under 75% filling situation, although the seven reading and three writing scores have dropped to a certain extent, they can still reach a level close to 100MB/s, which is still excellent. In PC Mark 10, there are storage test items specifically for solid-state drives, which are divided into two items: data disk and system disk. Non-cache disks are more suitable for use as data disks. Many users use them to store data, such as large games, videos and other files. The 1TB version of Lexar NM1090 SSD has a comprehensive score of 14468 points in the data disk test project, and its bandwidth speed It reached 1996.36MB/s, with an average access time of 10us, crushing the performance of all historical solid-state drives tested. In another system disk test, the Lexar NM1090 SSD 1TB version also performed very well, with a comprehensive score of 7652 points, a bandwidth speed of nearly 1000MB/s, and an average access time of only 17us. , it can be said to be the fault lead. This kind of performance is very suitable whether it is used as a system disk or a data disk.

Tested performance

The 1TB version of Lexar NM1090 solid-state drive is equipped with SLC dynamic cache and 2GB independent cache, which can reduce system waiting time and improve data transfer speed and performance. Next, let’s test its cache interval size and what is the real speed performance of internal and external buffering. We directly use the urwtest software to conduct a full disk write test. Judging from the real-time write data in the last line, the actual write speed of the Lexar NM1090 SSD 1TB version in the initial stage is about 4000MB/s, and the average speed reaches 3800MB/s. above. When the hard disk capacity is written to about 111657MB (about 109GB), the actual writing speed will drop to about 2000MB/s, which is half speed. It can be seen that the average writing speed is still maintained at 3600MB/s at this time The high position above. In the final stage of writing, when the remaining capacity of the drive letter space is about 127577MB (approximately 124GB), the writing speed triggers a secondary slowdown. At this time, the actual writing speed is between 800MB/s-1000MB/s This kind of slowdown speed is quite good. After all, the full-speed read and write speed of many external mobile hard disks is only 1000MB/s. However, due to some limitations and rules of the Windows system, the speed performance when users copy and copy real data may deviate from the theoretical reading and writing speed and actual reading and writing speed of the software test. In order to be closer to the real performance, solid-state simulation is performed Tests such as disk-to-disk copying of files and intra-disk copying are necessary. Let’s look at the read performance first. We copied a game folder compressed package from the Lexar NM1090 SSD 1TB version to another Lexar NM800 Pro SSD with PCIe4.0x4 specifications. The actual performance of a single file The maximum reading speed can reach about 4.5GB/s. When reading dual files, the actual maximum reading speed is about 2.1GB/s. Let’s look at the writing performance again. This time, we copy the folder from the Lexar NM800 PCIe4.0x4 solid-state drive to the Lexar NM1090 solid-state drive 1TB version. The actual maximum writing speed of a single file is 3.3GB/s, the actual maximum writing speed of dual files is 2.1GB/s. Then there is the performance of in-disk copying. Directly copy the existing single-folder data package in the 1TB version of Lexar NM1090 SSD and then paste it. The maximum in-disk copying speed at this time is 3.4GB/s. Of course, the above results are based on the ideal environment inside the buffer. What about the performance after the buffer? After multiple cross-disk copy and write tests, the actual speed after buffering is basically maintained at around 1000MB/s. Judging from the above sets of test results, the overall performance of the Lexar NM1090 SSD 1TB version is better than the PCIe4.0x4 flagship SSD, especially the slowdown speed can reach 1000MB/s, and it is still the version with the lowest capacity. , will not give people the feeling of a big gap. The last thing is the temperature performance. When in pure standby without any data exchange, the standby temperature of the 1TB version of Lexar NM1090 SSD is 43 degrees, which is only two or three degrees higher than the PCIe4.0x4 solid state. Under a full-speed workload such as urwtest, where data packets are continuously written to the disk for 5 minutes, the temperature displayed by CrystalDiskInfo reaches 70 degrees. In a summer room without air-conditioning fans, such temperature performance is not good. Surprisingly, the heat dissipation vest does have a certain effect. Like colleagues who use cameras to shoot videos, they are not always worried about the temperature of the body being too high and unable to work.

Summary

Lexar NM1090 PCIe5.0 Gen5x4 NVMe SSD can be regarded as the top super flagship SSD in terms of specifications and theoretical reading and writing performance. Even in real reading and writing scenarios on Windows systems, the peak speed is relatively high. Compared with PCIe4.0x4 solid-state, it is also leading in all aspects, and its SLC dynamic cache technology and independent memory are also faster and more efficient in recycling garbage cache. It is almost the answer for users who pursue the ultimate solid-state performance. The 1TB version we tested this time also comes with a cooling vest with RGB and built-in fans, which is complete for a solid-state drive in terms of design and functionality. The only thing you need to consider may be whether the motherboard has an M.2 slot that supports PCIe5.0 speeds. Old users also know that the test hard drive has always been Lexar's NM800. This time it has received the NM1090 and it has become even more powerful. We also hope that Lexar can continue to launch sincere and reasonably priced storage products to become a consumer-grade product. Market disruptor.

The above is the detailed content of Lexar NM1090 PCIe5.0 Gen5x4 NVMe SSD experience: 12000MB/s ultra-high-speed reading, RGB cooling vest is a perfect match. For more information, please follow other related articles on the PHP Chinese website!
