Phison Presents the E37T Controller for Manufacturing More Affordable PCIe 5.0 SSDs

The company Phison has officially launched its new E37T controller, a component specifically designed to build solid-state drives that use the PCIe 5.0 interface. This strategy aims to reduce the cost of producing these high-speed devices and bring them to a wider audience. 🚀

A DRAM-less Architecture to Reduce Prices

The main innovation of the E37T controller is that it operates without integrating a dedicated DRAM memory buffer. This architecture, known as DRAM-less, allows manufacturers to significantly cut the final price of SSDs. The chip handles all communication and data using only NAND flash memory and the computer's system resources.

Key advantages of this approach:
  • Lower manufacturing cost: Eliminating the DRAM chip and its associated circuitry reduces the necessary components.
  • More accessible end products: Allows creating PCIe 5.0 SSDs for the mass market at a more competitive price.
  • Design simplification: Manufacturers can develop simpler and more compact circuit boards.
The promise of cheap PCIe 5.0 SSDs sounds good, though the real test will be to see how they perform in everyday use.

Maintaining PCIe 5.0 Performance is a Priority

Despite lacking its own DRAM, Phison has designed the E37T to operate at the speed that defines the PCIe 5.0 standard. The company implements advanced algorithms that manage the cache and process input and output operations very efficiently.

How it balances cost and speed:
  • Intelligent management algorithms: Optimize the use of NAND flash memory to compensate for the lack of dedicated DRAM.
  • Direct communication with the system: Leverages the system's RAM resources for certain caching tasks.
  • Focus on efficiency: The design prioritizes a stable data flow to avoid degrading the user experience.

The Future of Fast and Accessible Storage

This move by Phison could accelerate the mass adoption of the PCIe 5.0 interface in storage. The challenge will be for users to perceive the same performance in real-world situations, such as transferring very large files or filling the downloads folder at maximum speed. DRAM-less technology demonstrates that it is possible to strike a balance between price and the latest generation of speed. 💾
