I want to leave an SD card plugged in the imac.

 

I was curious if there are any limitations on size and speed?

 

Thanks

    as far as addressing storage space then the limitations should be that of a normal harddisk

    as far as speed then the speed is how fast the disc is if the interface of the computer can't keep up then the disc will wait for it same with a car being able to run faster then the speed limit

    SD card is not a disk....flash memory...#confused or misreading something.

    I wouldn't use an SD card any larger than 64 GB. I am not even sure if these are made.

    ok thanks,

     

    I just wanted to make sure that I could use a 64 GB SD card.

     

    As far as speed, I was looking on amazon and noticed that sd cards come in a variety of different speed flavors.

     

    30 MB/s

    40 MB/s

    45 MB/s

    80 MB/s

     

    I'm guessing for film and video you'd want the fastest I just didn't know if there were any limiations,

    About the SD and SDXC card slot

     

    You can use any currently available capacity. ASC users have reported success with 128 GB cards. 256 GB cards are available from Lexar but the approximate price per GB becomes about $2 vs. $1 for lesser capacities.

     

    Speeds vary dramatically among manufacturers so shop around.
