Phison at the 2026 Computex showcased its next-generation SSD controllers based on new foundry nodes, implementing new PCI-Express Gen 6 (256 Gbps), and its reference SSD demos. The company also unveiled its newest Pascari-branded enterprise SSDs. We begin our tour with the new Phison X3 series 8-channel SSD controller that implements PCIe Gen 6, the future interconnect standard that could debut in 2027-28. The controller features a PCI-Express 6.0 x4 host interface, and supports NVMe 2.3 protocol, including computational storage. While there are no host platforms besides development kits handed out by Intel, a Gen 6 SSD powered by the X3 will typically offer sequential transfer rates of 28 GB/s, double that of today's Gen 5 SSDs, with 4K random access speeds of up to 6.8 million IOPS.

Next up is the new Phison E37T, the successor to the E27T. This is a very interesting PCIe Gen 5 client SSD controller that's DRAMless, while offering sequential speeds of up to 14.9 GB/s reads, with up to 13.2 GB/s writes—performance you'd expect from a high-end controller with DRAM cache. It also tops out at 3 million IOPS 4K random access. The best part? Phison claims an active power of under 2.3 W, which means drives based on this chip can make do without any active cooling, perhaps just a heat-spreader or a lightweight heatsink. Phison showed us their reference SSD based on the E37T, along with a performance demo.

Phison Electronics, a global leader in NAND flash controllers and storage solutions, today announced that its Pascari D206V PCIe Gen 5 data center SSD has received the prestigious COMPUTEX Best Choice Golden Award, recognizing the next generation of innovation in ultra-high-capacity enterprise storage for AI and modern data center infrastructure.

The Pascari D206V is designed to address the growing industry challenge of efficiently scaling storage capacity for AI, cloud and data-intensive workloads without increasing operational complexity or infrastructure costs. Delivering up to 245.76 TB in a single U.2 PCIe Gen 5 SSD, the D206V enables hyperscale and enterprise customers to significantly increase storage density while reducing rack footprint, power consumption and total data center OPEX.
