FIRST LOOK: At Computex 2026, Phison wasn't just talking about faster SSDs. The company used the show to outline where it thinks flash storage is headed, and how to get there without blowing the power budget. Its new controllers and enterprise drives all revolve around the same problem: squeezing out more performance without letting power consumption and heat get out of control.
That balancing act is most visible in its upcoming PCIe 6.0 controller, the X3, which is edging closer to market readiness. The controller uses a PCIe 6.0 x4 interface and supports NVMe 2.3, targeting roughly twice the throughput of today's high-end PCIe 5.0 SSDs. Phison is aiming for sequential speeds of up to 28 GB/s and up to 6.8 million IOPS in random workloads.
Those numbers put the controller well ahead of what most currently shipping systems can support. It's worth mentioning that PCIe 6.0 platforms remain limited to development environments, and Phison's own demonstrations are running on specialized hardware.
Still, the company is moving the X3 out of early testing and into reference designs that resemble shipping products. Phison plans to begin sampling the controller in December and ramp volume shipments in mid-2027.
