- The Memory Stick Pro-HG Duo format is proprietary to Sony and less universally compatible than SD cards.
- A 4GB capacity might be considered small for modern digital cameras or devices that record high-resolution video or large image files.
- Achieving the maximum write and transfer speeds requires a "compliant host device," meaning older or non-optimized devices may not fully benefit.
- The card type is specific to certain Sony devices, limiting its use in other brands or universal card readers without an adapter.
- While fast for its generation, its theoretical maximum transfer speed might be surpassed by newer, faster card formats like UHS-II SD cards.
