A pair of new controllers developed by Silicon Motion will challenge its popular products Phison At the high end and also in the middle market - and more and more players will be able to move forward in support of the new connectivity standard and its increased performance
M.2 configuration SSDs that support PCI-Express 4.0 connectivity are not entirely new, but with a second generation of home support AMD, Support fromAMD And Intel in the mobile market and a slightly clearer time frame for the desired support from Intel in the desktop world as well - it seems that they are going to become common and much more successful in a short time.
After we got Kerry SSD Supporters from home סמסונג, Western Digital And especially the Taiwanese Phison, which is happy to offer its technologies to anyone who pays - it seems that the joining of Silicon Motion (also from Taiwan) to the race will contribute to increasing supply and competitiveness and also improving average prices which today still tend to be tens of percent higher than drives NVMe In the standard PCI-Express 3.0.
Silicon Motion's first offering in the PCIe 4.0 lineup will include three models of controllers storage - With the SM2267XT devoid of dedicated dynamic memory (similar to previous XT controllers of the company we had the opportunity to get to know) at the lower end, based on an old 28-nm manufacturing process and with four-channel support memory For continuous read speeds of up to 3,900 megabytes per second, continuous write speeds of up to 3,500 megabytes per second and random performance of up to 500,000IOPS in both read and write. The numbers of the SM2267XT are not the most impressive in the world ofNVMe All in all, but they are significantly better than any other mainstream controller the company has offered us so far and in fact also higher than the performance of its leading SM2262EN controller in the PCIe 3.0 generation, so you can certainly hope and expect more performance for less money with the transition to the contemporary era.
The SM2267XT will also have an alternative as it will support built-in dynamic memories of the type DDR4 Or LPDDR4 - the SM2267, which is designed to deliver similar numerical performance on paper but should still enjoy the ability to deliver them at shorter time intervals and improved efficiency compared to its brother, which had to settle for HMB technology in which a small portion of systemic DRAM memory is stored as a layer Remote cache of storage The flash.
The most exciting news from Silicon Motion in the new generation will come in the form of the SM2264 model (the common logic of larger model numbers indicating superior performance does not apply in the company's labs, it turns out), which will be based on a modern 12-nm production process with four Cortex-R8 cores and support In eight channels for flash chips - get continuous read speeds of up to 7,400 MB per second, write speeds of up to 6,800 MB per second and also random performance with small 4KB files of up to 1,000,000IOPS in write and read (thanks to the use of memories DDR4 Or built-in LPDDR4, as required). The performance of the SM2264 could provide fair and important competition for the performance of the popular Phison E18 controller, among many dozens of companies that are unable to finance the development and self-production of controllers storage.
Battle of the ControllersSSD This new may result in many models with minimal differences between them (identifying the flash chips used sometimes has a minimal effect on the capabilities compared to the controller).SSD Itself) - but we hope that everyone will be quality and agile without exception, thus helping consumers go for the most affordable prices without being overly apprehensive. Expect more updates soon.
