    Not even in Raspberry Pi, nowadays Hard Disks are getting replaced with Solid State Drives in latest computers. It has the following advantages.

    • More Durable
    • Faster Performance
    • Less Power Consumption
    • Light Weight
    • Long Life
    • Cost Efficient for Long Run (energy savings, long life, performance)
    • Very Low Heat Dissipation
    • No noise is produced as there is no moving parts

    I already posted the reason for choosing SD Card. Windows will not work with Raspberry Pi. Operating system is working on Hardware. So hardware must be compatible with Operating System. We can only use OS customized for Raspberry Pi

    SD Card can treated as a Solid State Drive (SSD).

    Usually we call SSD for drives we are using in computers instead of Hard Disk. Memory Cards are usually smaller than SSD.

    Although Memory Cards and SSDs are using same technology, their application, functionality and size are distinctive.

    Your questions are going outside the scope of this topic. You can open a new topic for asking such questions.

    Size depends on the Operating System you are using. You can check sizes of different operating systems. You may customize it to reduce size by removing unwanted features. If you want to customize Linux, please go to a Linux forum.

    But there is no relation with Operating System Size and SD Card. SD card is chosen because of its advantages. Up to 512GB SD cards are available in the market.
