Which Is better in Mikrotik ?

Hi everyone, if you want to starting cache server+log server+user man server+hotspot server+in mikrotik,which device do you prefer to use for better performance ?

which is better ?
32GB Flash or 32GB MICRO SD Card!

thanks for your answers.

Look at the specs of those 2 things, which is faster, and which has a larger amount of writes per lifetime?

Also, the CPU is probably more important to be able to handle all that, depending on number of users.
