Possible disadvantages of Raspberry Pi

• Limited Performance
  Despite improvements in newer models, Raspberry Pi devices still have limitations in processing power compared to full-fledged computers, which can be a bottleneck for intensive applications.
• Storage Constraints
  The usage of micro SD cards for storage can be a limitation in terms of both speed and capacity, compared to traditional hard drives or SSDs.
• Peripheral Dependency
  To fully utilize a Raspberry Pi, additional peripherals like keyboards, mice, monitors, and power supplies are needed, which can complicate setups and add to the overall cost.
• Connectivity Limitations
  Though equipped with various connectivity options, the number of USB ports and network interfaces may be limited, imposing restrictions on connected devices.
• No Built-in Real-Time Clock
  Raspberry Pi lacks a built-in real-time clock (RTC), requiring an additional RTC module for applications that need to keep track of time when powered off.
• Software Compatibility
  Certain software and applications are not optimized for the ARM architecture of the Raspberry Pi, potentially limiting the available software and compatibility with x86 applications.
