The PCIe 4.0 interface enables data transfer speeds twice the speed of its predecessor, PCIe 3.0, and will now form the basis of the new generation of Micron SSDs for both OEM systems and the consumer market. These new SSDs are based on the brand’s new generation of 3D NAND memory that combines the new controller architecture with 176 cell layers for higher available densities.
Micron’s First PCIe 4.0 SSDs
The new SSD Micron 3400 PCIe 4.0 are designed for high performance requirements; They come in the M.2 2280 form factor and offer storage capacities ranging from 512GB to 2TB using 176-layer TLC-NAND memory chips. As for the controller, Micron is based on an internal design that they have not specified but that supports the PCIe 4.0 interface with NVMe 1.4 protocol, which compared to the current Micron 2300 will provide twice the performance, so rates are expected about 6,600MB / s read and up to 5,000MB / s write rate.
On the other hand we have the Micron 2450, more oriented to an “affordable performance”. These SSDs also carry 176-layer NAND TLC but will be offered in capacities ranging from 256 GB to 1 TB nothing more, in quite different form factors since in addition to the usual M.2 2280 we will see much shorter formats for format equipment small, including M.2 2242 and M2.2230 only 3 centimeters long.
The Micron 3400 and 2450 series must meet Intel’s Project Athena requirements due to their “advanced energy efficiency” and be on the “Intel Modern Standby Partner Portal platform component list”. SSDs are also validated according to AMD and Microsoft Windows PCIe power and speed policy guidelines.
At the moment Micron has not revealed the complete technical characteristics beyond the image that you can see above, nor have they revealed their price and date of arrival in stores (they have said that they are already producing them in mass so it should not spend a long time until we see them in stores).
176-layer flash with Phison E18 controller
As usual, Micron will not only use its new NAND Flash technology in its new products but will also make it available to external customers. So we can expect to see within not many high-end SSDs with 176-layer NAND and the enthusiast-built Phison E18 controller, a controller we’ve already seen that manages to break through the 7,000MB / s barrier and does so with you also grow.
For now they have not said anything about the partners that will use this new Micron technology, and surely until they reach the market we will not have news of it.
