The current crop of PCIe Gen 5 based M.2 NVMe SSDs run scorching hot to deliver sequential transfer speeds of 10 GB/s, requiring some massive cooling solutions with tiny fans. All this might change, as Phison, a leading SSD controller manufacturer, unveiled three new controllers at the 2024 International CES. One of these that stands out, is the PS5031-E31T, which is built on the 7 nm node, and could power the first Gen 5 SSDs delivering 10 GB/s without elaborate cooling solutions. This is a big upgrade from the 12 nm node used by their first Gen 5 controllers. The PS5031-E31T is a DRAMless controller meant for mainstream Gen 5 SSDs. This controller has a 4-channel flash interface (16 CE), a PCI-Express 5.0 x4 host interface, supports capacities of up to 8 TB, and is claimed by Phison to offer sequential transfer rates of up to 10.8 GB/s, and up to 1500K IOPS random access; exceeding the fastest Gen 4 SSDs.

Phison also updated its high-end controller lineup with the new PS5026-E26 Max14um. This is a variant of the E26 that's designed for the upcoming Micron B58R NAND flash chip that offers 2400 MT/s per channel transfers. Over the 8-channel interface of the E26, this finally unlocks sequential transfer speeds exceeding 14 GB/s reads, and 12.7 GB/s sequential writes. This is merely a revision of the existing E26 with updated power-optimized firmware, the underlying silicon is identical. The E26 Max14um is the first controller to surpass 1000 MB/s in all three PCMark 10 storage tests. We have a sample of an SSD powered by the E26 Max14um in our labs, and will post our review soon.

Phison Electronics, a global leader in NAND controllers and storage solutions, will showcase its high-speed transmission and storage solutions at the annual Taipei International Computer Show (COMPUTEX) in Taiwan. At COMPUTEX, Phison will illuminate the future of intelligent storage. The show kicks off on Tuesday, May 30 through Friday, June 2.

Building upon its globally acclaimed flagship PCIe 5.0 SSD PS5026-E26 storage solution, Phison Electronics will unveil its latest offering at COMPUTEX. The new addition is the PCIe 5.0 DRAM-less SSD controller PS5031-E31T, featuring a 7 nm process that ensures low power consumption. With an impressive maximum read/write performance of 10.5 GB/s, it represents a PCIe 5.0 SSD storage solution that excels in performance and power efficiency. In addition, Phison will introduce the next-generation PCIe 4.0 DRAM-less SSD controller PS5027-E27T, engineered with a 12 nm process and offering a remarkable maximum read/write speed of 7400/6400 MB/s. It is anticipated that the PCIe 5.0 PS5031-E31T and PCIe 4.0 PS5027-E27T SSD storage solutions will comprehensively meet the diverse needs of PC OEM partners and customers.
