Storage performance is about to take a quantum leap forward. Phison has unveiled two groundbreaking SSD controllers—one for the next generation of PCIe connectivity and another that eliminates DRAM without sacrificing speed or efficiency.

The new Phison X3 series controller, designed for PCIe Gen 6, promises sequential transfer rates of up to 28 GB/s—a dramatic improvement over current Gen 5 SSDs. This controller is built around an 8-channel architecture and supports NVMe 2.3 protocol, including computational storage features that could redefine how data is processed at the drive level.

Complementing this is the Phison E37T, a DRAMless PCIe Gen 5 controller that delivers up to 14.9 GB/s reads and 13.2 GB/s writes while consuming less than 3 W of power. This makes it ideal for ultra-thin devices where heat dissipation is a concern, as no active cooling may be required beyond a basic heatsink.

Enter Pascari: Enterprise-Grade Reliability

Pascari, Phison's enterprise storage brand, has also introduced a lineup of high-capacity drives designed for data centers and AI workloads. The D201E series spans capacities from 1.6 TB to 15.36 TB, offering up to 14.8 GB/s sequential speeds and 3.3 million IOPS. Meanwhile, the X202Z is a U.2 15 mm Gen 5 drive with similar performance, while the D250P in E1.S form factor ranges from 480 GB to 3.84 TB.

What This Means for Buyers

  • PCIe Gen 6 SSDs could appear as early as 2027-2028, with the X3 controller leading the charge.
  • The E37T’s DRAMless design reduces power consumption while maintaining high-end performance, making it a strong contender for client devices.
  • Pascari’s enterprise drives are optimized for NVMe 2.1 and computational storage, hinting at future-proofing for AI workloads.

For everyday buyers, the implications are clear: faster storage with lower power consumption is on the horizon. However, widespread adoption will depend on the availability of PCIe Gen 6 platforms, which are currently limited to development kits from Intel.

What’s Next?

While Phison and Pascari have set ambitious benchmarks, the real test will be how quickly these technologies translate into consumer products. Pricing and availability remain unconfirmed, but one thing is certain: storage performance just got a major upgrade.
