Why is the SM2320-Based PSSD Better Than Traditional Enclosures with Discrete Chips?

 

In the competitive world of portable storage, performance, reliability, and efficiency are critical factors that users consider when choosing a solution. The SM2320-based Portable Solid State Drive (PSSD) offers significant advantages over traditional enclosures using discrete chips. This article will explore these benefits and provide a detailed comparison.

Introduction to the SM2320 Solution

The SM2320 controller from Silicon Motion is an innovative single-chip solution designed specifically for PSSDs. This design integrates the USB bridge and SSD controller into one chip, allowing direct data transfer from the USB-C interface to the NAND flash. This approach eliminates the need for intermediate conversions, which are typical in traditional enclosures.

 

In contrast, traditional enclosures utilize a discrete chip approach where data is transferred from USB-C to a bridge chip, then to an M.2 interface (which utilizes the NVMe protocol), and finally through the SSD controller to NAND flash. This additional step introduces extra heat and performance losses due to protocol conversion and data movement.

Key Advantages of the SM2320-Based PSSD

  1. Direct Data Transfer Path
    • Efficiency: The SM2320 solution facilitates direct data transfer from USB-C to NAND flash, eliminating unnecessary protocol conversions. This reduces heat generation and performance loss, ensuring maximum efficiency .
  2. Superior Performance
    • Speed: With support for USB 3.2 Gen2x2, the SM2320 controller offers sequential read and write speeds up to 2,100 MB/s and 2,000 MB/s, respectively. This high-speed capability is ideal for tasks requiring rapid data transfers, such as video editing and large file migrations. Traditional enclosures with discrete chips cannot achieve speeds as high as 2,000 MB/s, making the SM2320-based PSSD the clear performance leader .
  3. Enhanced Efficiency and Reliability
    • Power Consumption: The integrated design reduces power consumption and heat generation, enhancing efficiency and reliability. This is crucial for maintaining performance during extended use and in portable applications where power efficiency is essential  .
  4. Compact and Cost-Effective Design
    • Size and Cost: The single-chip integration reduces the PCB space required, resulting in a more compact and portable PSSD. Additionally, it lowers manufacturing costs by eliminating the need for separate bridge chips, making SM2320-based PSSDs more affordable without compromising on performance .
  5. Advanced Features for Data Integrity and Security
    • Data Protection: The SM2320 includes advanced features such as NANDXtend ECC, end-to-end data path protection, AES-256 hardware encryption, and support for TCG Opal 2.0 security standards, ensuring data integrity and robust security for sensitive information .
