Shulou(Shulou.com)11/24 Report--

"create good things for the people" has always been the product development concept of aigo. In particular, the rapid development of domestic solid-state hard drives in recent years has indeed brought a lot of exciting good products to users. During the Singles Day holiday, aigo launched a new PCIe 4.0 solid state drive-SMI70, which uses SMI's latest SM2268XT master, which can achieve the performance of 7480MB/s without cache, coupled with an initial price of 1549, which is cost-effective.

The author of this is a 4TB capacity, open the label, you can clearly see the overall design of aigo SMI, the top for the main chip, below the neatly arranged four Flash flash memory particles, and there is no independent cache location. And 4TB capacity still uses an one-sided design, not only to facilitate the use of desktops, but also to upgrade the game can also maximize the preservation of heat dissipation space, or very considerate.

The main controller is Huirong SM2268XT, which is the first master chip in the industry to support 3200MT/s rate NAND IO Speed. It uses dual-core Cortex-R8 processor, supports PCIe Gen4 NVMe 2.0 technology, and can support TLC and QLC NAND.

This master is also a DRAM-less cacheless mode architecture, which can still provide ultra-high transfer rate with the help of HMB function, and is currently the fastest DRAM-less solid state disk solution.

In the SSD master chip solution market, SMI has been providing a wide range of services for OME customers, including performance, cost, form factor, etc., through its own research and development technology, it can support the 3D NAND of most NAND flash memory manufacturers in the market, and provide a complete firmware suite to help OEM complete the fastest new products to market.

At the same time, this SM2268XT master of SMI has also completed the PC OME SSD product certification, and there is a very perfect and stringent process from new product R & D planning, internal verification to OEM testing and customer procurement, so SSD based on SMI master control has a strong guarantee in terms of performance, power consumption and stability, and has the title of original factory master control in the industry.

In terms of particles, the Yangtze River used by aigo SMI70 stores the new generation of TLC 3D NAND flash memory particles and uses the self-developed Xtacking 3.0 stacking process for better performance, lower power consumption and more durable write capacity.

Before testing, let's take a look at the parameters of the aigo SMI70 4TB solid state drive. As can be seen from the picture above, the solid state drive uses the PCIe Gen4X4 specification and the standard is NVMe1.4.

In the CrystalDiskMark read and write test, the continuous read performance of SMI70 reaches 7451MB/s, and the continuous write performance also reaches 6453MB/s, which is very outstanding in performance.

In AS SSD testing, we often see that the data is not good-looking, in fact, the data type of this software is very extreme, 100% is a data model that cannot be compressed. However, in this case, SMI70 still achieved 9801 good results, it can be seen that the performance of this master control can not be underestimated.

Next, we use PCMARK10 to simulate the normal system operation scenario to test the actual performance of this solid-state disk, and show it directly in a numerical way. In the complete system disk test, the final score is 3654 points, the bandwidth is 569.37MB/s, and the average access time is 47 μ s.

A storage performance test is also added to the 3Dmark test. after the test, the SMI70 score is 3792, the average rate is 644.65MB/s, and the latency is also 47 μ s. The main points for the game load above, such as loading "Battlefield Fengyun 5" when the bandwidth is 1060.72MB/s, or very tough.

Using "final Fantasy 14" Benchmark to test SSD is still very advantageous, because it has a number of built-in game scene loading time running items, we retained the intermediate results after three tests, and the game loading task was completed in 6.3 seconds.

When experiencing the game "the Wild Dart", the biggest feeling is that the loading time of the game is very short, without a long wait, you can quickly enter the game interface directly. And the map of this game is very large, and the game scene is also very complex, so it is very necessary for SSD to have a fast reading ability, which can ensure the fast and stable switching of game scenes. Therefore, with the sequential reading strength of SMI70 up to 7483MB/s, the experience of the whole game is very good.

In addition, this SSD is also very suitable for regular video editing users, not only large enough to store more material, but also significantly improved in terms of efficiency. The test here is to import the material into SMI70, then transcode the output, and record the time required for transcoding. The material is 4K ProRes and the file size is 15GB. Through the actual test, the transcoding time of this SSD is only 1 minute and 14 seconds. This speed is really very fast. I believe it can greatly improve the later creation efficiency of content creators.

Summary

In fact, for a long time before, solid state drives with DRAM cache were known as high-level SSD, which has a great advantage over DRAM-less solid state drives in terms of performance. However, from the test results of this new SMI70 product released by aigo, it seems that DRAMless solid state drive is overtaking around the corner, and its performance is not inferior to that of DRAM flagship products after carrying SMI SM2268XT master control. at the same time, it also has the advantages of low cost, low power consumption and low fever without DRAM, and more importantly, there are full reduction and other activities during the Singles' Day period. 4TB capacity to hand price is only 1549 yuan, and then enjoy a single return of 20 yuan E card, superimposed discount is more worthwhile to start.
