Who is SSR after all, with sales of PM1643A and PM9A3 on par

&Nbsp; The two most popular models in Samsung's enterprise SSD domestic market recently are the PM1643A and PM9A3, which can be said to be sales giants of SAS and U2. In a market that is already struggling, these two dark horses still maintain high sales, which proves their position. However, who is the enterprise level hard drive; SSR” What about it< Br/>




&Nbsp& Nbsp& Nbsp& Nbsp; The PM1643A has a total of 6 capacities, ranging from 960G to 30.72T. The SAS interface can accommodate SATA interfaces downwards, and the SAS interface has also undergone significant improvements. It provides both 3.5-inch and 2.5-inch interfaces, making it suitable for different server environments< Br/>

&Nbsp& Nbsp; In this way, it seems that the performance of PM1643A is still very impressive. The capacity provides consumers with more choice space, and with a good price, cost-effectiveness is indeed his killer weapon. Let's take a look at the data table of PM9A3< Br/>

&Nbsp& Nbsp& Nbsp& Nbsp; The PM9A3 hard drive uses a U2 interface, which combines most of the characteristics of SATA and SAS interfaces, and is compatible with both interface specifications. It supports the NVMe protocol and even improves power supply capacity. The PM9A3 adopts a double-sided four chip layout, with a tantalum capacitor in the middle and PLP power failure protection. In terms of main control, the PM9A3 adopts the same model of 8nm main control Elpis as the 980Pro/PM9A1, and surprisingly, the PM9A3 has two temperature control sensors. The hard drive itself has strong performance and actual heat generation is not low< Br/>




&Nbsp& Nbsp& Nbsp& Nbsp; From the above, it seems obvious that PM1643 and PM9A3 cannot be compared to each other. The working scenarios of the two are not the same. PM9A3 intuitively gives the impression that the performance is higher than the former, but the capacity selection is not as large as the former. The PM1643A has a relatively large capacity and is undoubtedly the best choice for SAS and SATA suitable working scenarios. Although the PM9A3 can support the interface of the former, the performance loss is also significant< Br/>


&Nbsp; It can be said that the art industry has a specialization, and these two can only shine in their own scenarios, and not conflicting with each other is precisely the core reason why these two sales are keeping pace. The sales volume of all products is ultimately based on social and market demand, and the trend of SSD can also be seen in the recent trend of the electronic market. subjectively speaking, both should be based on" SSR”, Or the real&quo; SSR” It hasn't appeared yet, what do you think< Br/>
