Phison Brings PCIe 6.0 SSD Controller Roadmap to Computex

Phison's Computex 2026 exhibit included the X3 controller, a PCIe 6.0 SSD platform that the company says can reach 28 GB/s of sequential bandwidth and 6.8 million IOPS in random workloads. The controller is also described as supporting drives as large as 2 PB, which places the design squarely in the high-capacity enterprise storage discussion. The company also highlighted the E37T for PCIe 5.0 SSDs, with a stated 4.5 W power profile. That lower-power angle matters for client and compact systems where PCIe 5.0 storage has sometimes been constrained by thermals and efficiency. For the memory market, the announcement is more of a technology roadmap signal than a direct pricing event. It keeps pressure on SSD controller vendors to prepare for PCIe 6.0 while also improving PCIe 5.0 efficiency, but the available report does not include shipment timing, controller pricing, NAND commitments, or customer design wins.
