    I found benchmarks of micro SD card in various websites. For reading those values and deciding and understanding and clarifying which one is relevant for adoptable/ swapping. I want to know what speed value is relevant for Internal/External storage

    for **system applications booting** of android and basic applications like chrome YouTube Facebook WhatsApp and other apps functioning **NOT FOR GAMES OR VIDEOS**

    Online Websites and Andro benchmark app and gives values of

    Sequential read and write 1000 MB/s
    Random read and write 512 MB/s
    Random read write QD1 4KB MB/s
    Random read write QD32 4KB MB/s
    Random read write QD1 4KB IOPS
    Random read write QD32 4KB IOPS


    For using my MicroSDcard as adaptable OR swapping storage

    **Now my questions are :-**

    1. System booting Android applications **read and write randomly or sequentially** which values more relevant means application writes randomly or sequentially

    2. What **Queue Depth QD** is relevant for Booting android system and basic applications **QD1 or QD32**

    3. Which **Block size** android applications work in **4KB or 8KB 512 Bytes** block size on what ground it should be compared

    4. what speed of **reading or writing** is more relevant for booting system and general application an adoptable swapping storage

    5. what value should be compared OR more relevant **MBPS or IOPS** for QD1 4KB and QD32 4KB while considering applications writing or reading speed

    6. what **RANGES OF VALUES** of following benchmarks criteria will be sufficient or believed excellent for booting and system application

    A Sequential Read 1000MB/s
    B Sequential Write 1000MB/s
    C Random Read 512 MB/s
    D Random Write 512MB/s
    E Random Read QD1 4KB MB/s
    F Random Write QD I 4KB MB/s
    G Random Read Qd32 4KB MB/s
    H Random Write Qd32 4KB MB/s
    I Random Read QD1 4KB IOPS
    J Random Write QD I 4KB IOPS
    K Random Read Qd32 4KB IOPS
    L Random Write Qd32 4KB IOPS
