GIGABYTE Teases Upcoming PCIe 4.0 NVMe SSD – Coming Soon
GIGABYTE Takes to Twitter to Tease Gen4 SSD Ahead of Computex
GIGABYTE’s Japanese AORUS Twitter account posted a teaser of a mysterious PCIe 4.0 NVMe SSD which is “coming soon”, and with Computex nearly upon us we should know more about it soon. ComputerBase (German language) has the story and references the previously revealed Phison Gen4 SSD controller shown at CES, though the exact controller within this unannounced drive has, naturally, not been confirmed (with only a cagey “it’s a secret” in reply to a question about it).

Assuming it could be using a Phison E16 controller we would be looking at PCIe 4.0 x4 SSD with 8 channels supporting 96-layer TLC 3D NAND. The ComputerBase article also points out that Silicon Motion will also have a PCIe Gen4 option with their planned SM2264 controller, which has been on the company’s roadmap since 2017. We await further details, and with both GIGABYTE and Phison attending Computex we will hopefully have a more official announcement in the coming days.
"Phison predicted sequential transfer rates of up to 4,800 MB / s in January and 4,400 MB / s in writing, as well as up to 900,000 IOPS in the random reading / writing of 4K data. Ultimately, performance depends not only on the controller, but also on NAND flash, cache configuration, and firmware. The rumor mill even speaks of 5,000 MB / s reading and 4,400 MB / s writing for the Aorus NVMe Gen4 SSD and expects the use of 96-layer TLC 3D NAND from Toshiba and Western Digital."
