    What is Relevant benchmark values for microSDcard performance?
    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 storage. I want to know what speed value is relevant for Internal/External storage 
    
    
    Online Websites and Andro benchmark app and gives values of
    
    Sequential read and write
    Random read and write

    Random read write QD1 4KB MB/ps
    Random read write QD32 4KB MB/ps 
    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 applications
    
    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

    ocnbrze DON'T PANIC!!!!!!!!!

    i have no idea on benchmarks other then the speed of a microsd card. i would also be very cautious when using a sd card as your adoptable storage. since the phone will be reading and writing from the card, you will run the risk of wearing it out faster, the more you use the phone...and thus corrupting the card losing all of your apps data..

    there is a reason that samsung decided not have the adoptable storage option on any of their devices. it can potential cause more issues then it is worth IMHO.
