The brand new controller consists of a processor primarily based on 4 ARM Cortex-R8 cores with a frequency of 1.25 GHz and one ARM Cortex-M0 core. Though there was initially discuss of producing utilizing a 12nm FinFET course of, now there may be point out of TSMC’s 6nm EUV course of, which is meant to deliver a forty five% discount in energy consumption in comparison with 12nm. In comparison with the Phison E26 with an 8-channel DRAM reminiscence controller with 2400 MT/s, we even have an 8-channel controller right here, however it manages 3600 MT/s. It’s also mentioned that the brand new product ought to be capable to deal with sequential studying with a velocity of as much as 14.5 GB/s (generally it states “solely” 14 GB/s) and writing with 14 GB/s, within the case of random accesses then speak about 2 .5M IOPS for studying and a couple of.4M IOPS for writing. Nevertheless, there may be one catch. The primary SSDs with this controller are usually not anticipated to seem till 2025 (Silicon Movement, nonetheless, is getting ready a less expensive SM2504XT, which could possibly be out there as early as 2024, however even that may be a delay).
New SSD for the bus PCIe Gen5 though they’re hellishly quick, they’ve an issue with excessive consumption, which makes cooling with a big passive radiator problematic. Many producers subsequently resort to an lively resolution to lowering the temperature. A big a part of the excessive consumption of those SSDs is their controller, which is answerable for nearly half of the whole consumption. E.g. The Phison E26, which is used on many SSDs with PCIe Gen5, has a consumption of 5W, which is rather a lot for an SSD with a complete consumption of round 12-13W. New Silicon Movement SM2508which has been talked about for a while, could possibly be noticeably extra economical and is claimed to be lower than 3.5 W. Though this saved 1.5 W won’t do any wonders for the general consumption of the PC, it is going to however push the SSD nearer to the ten W restrict, and subsequently additionally the power to chill it passively.
