Kingston issued an article saying that the public is used to expressing the transfer rate of memory in MHz, but this is not a scientific and accurate way of expressing it. Now, Kingston has officially adopted standardized transfer rate units for its entire line of memory products and has updated all unit usages on its official website.

According to reports, when SDRAM memory was introduced, its data transfer speed was measured in the same way as the motherboard clock. Therefore, Volkswagen adopts the frequency unit “MHz” as a standard to measure the performance of SDRAM.
But after DDR SDRAM came into the market, its data transfers occurred on the rising and falling edges of the clock cycle. For a clock frequency of 100MHz, the data transfer volume of DDR SDRAM reaches 200 million times.
To more accurately measure the effective data transfer rate of DDR SDRAM, the unit of memory normalized transfer rate should be used, namely MT/s (Million Times per second, or “million times per second”).
Moreover, the information introduced on Kingston’s official website has been expressed in MT/s, and the rate of the latest DDR5-4800 memory is 4800MT/s.
