Is internal storage preferable over MicroSD?

Is internal storage faster than accessing MicroSD?

Like say you had 32GB internal + 32GB MicroSD versus 64GB internal? Would the 64GB internal be a smoother setup?

Technically speaking the internal memory would be the smoother setup.

However you'll have to be really really picky to notice a difference. If you use a class 10+ Micro SD card the difference is tiny between the Micro SD Card and the internal storage.

But yes, technically speaking the internal storage is faster for read/write speed.

As Ahmad says.
But it can also vary from OS to OS and/or phone to phone...
We have a Samsung Galaxy Camera in our household. By no means a slacker under the hood.
But: a thousand images on the internal memory load smoother and much faster than a hundred on the SD card (class 10). Also: image review right after capture is almost impossible unless you set to save to internal storage.

On the other hand: the same card in the Lumia 1520 and there's no difference in speed noticeable.

Internal memory would always be faster. Not because internal flash memory itself is faster, because of controller setup.

In order to read/write to internal memory or SD card you need to have a controller that would do the job. You can have separate controllers for internal and SD card, but that would be more expensive. Most likely there is single controller for both of them. While actual speeds of memory can be the same, internal memory would always be prioritized over SD card. Even with two separate controllers internal one would get access to CPU first and SD will have to wait. This happens due to OS, which is always on internal, has to have exclusive access and be always first in line.
