Phison recently confirmed in a blog post that PCIe Gen 5 SSDs will run hotter than their predecessors and require active cooling.
Last year, the manufacturer already revealed many details about PCIe Gen 5 SSDs, predicting that the first models will go on sale by the end of this year. PCIe Gen 5 SSDs will be able to provide data transfer rates up to 14 GB/s. With DDR4-2133 memory also delivering around 14 GB/s per channel, storage and DRAM can now work in the same space, plus there is a real prospect of L4 caching. Recall that now processors have L1, L2 and L3 caches. According to Phison, Gen 5 and above SSDs will be able to act as L4 cache for processors.
To reduce power consumption and heat dissipation, the new controllers will be switched from 16 nm standards to 7 nm standards. Another way to reduce heat generation is to reduce the number of NAND channels. Phison believes that from a practical point of view, it is not necessary to have eight channels to saturate PCIe Gen5 – four is enough and this can reduce the power consumed by an SSD by 20-30%.
In terms of temperatures, NAND memory typically operates at temperatures up to 70-85°C. For the PCIe Gen 5 controller, Phison set a limit of up to 125°C. If the memory temperature exceeds 80°C, the SSD will perform an emergency shutdown. However, too low a temperature is also bad. The optimal range is 25-50°C. According to the manufacturer, in order to keep the temperature of a PCIe Gen 5-enabled drive within acceptable limits, active cooling will be almost mandatory.
