In the past few weeks, at least three manufacturers of Corsair, Gigabyte, and Goodram have launched their own solid-state drives based on the Phison E26 master and PCIe 5.0 x4 interface, of which Corsair and Goodram products can only provide 10GBps continuous read speeds, while the Gigabyte Aorus Gen5 10000 can reach 12.4GBps.

Some users were confused about this before. Existing sources pointed out that the main reason for this is that the current 3D NAND flash memory does not have enough speed to eat up the main control performance, and the further reason is that Micron’s high-speed flash memory capacity is insufficient.
It is reported that the Phison PS5026-E26 supports eight NAND channels, which support different data transfer rates, but to run at full PCIe 5.0 x4 (15.754 GBps bidirectional), it requires 3D NAND flash memory particles with a 2400 MTps interface.
Micron launched this kind of memory in July this year, SK Hynix also launched this kind of flash memory in early August, and YMTC also launched its Xtacking 3.0 architecture, which also achieved a speed of 2400MTps.
Moreover, GALAXY is also testing its HOF Extreme 50 solid state drive, which also uses Micron’s 232-layer 2400MTps flash memory. In fact, all demonstrations of the Phison E26 are based on Micron’s latest 3D NAND flash memory, which can achieve sequential read speeds of up to 12GBps in their hands.
However, Micron’s 232-layer 2400MTps 3D NAND flash seems to have difficulty in mass production. The company needs some time to complete the mass production of the 2400MTps chip. According to the sources, they probably won’t be able to do that until sometime early next year.
At present, due to the supply problem of NAND flash memory, some Phison E26 solid-state drives that were launched early can only reach a read speed of about 10,000MBps. With the exception of the GIGABYTE Aorus Gen5 10000 SSD, which uses Micron’s 2400 MTps of flash, the Corsair and Kingston hard drives can only use 1600 MTps of flash.
