What is the highest supported micro SD capacity for the Nintendo Switch?

When the PS4 was updated to support an external Hard Drive Playstation listed

This is compatible with HDDs up to 8TB in size.

I just got my Nintendo Switch and am looking to buy a Micro SD for it but when i started to think how big it should be i remembered the PS4 and don't want to get a highest capacity Micro SD Card only to find out that it isn't supported/compatible.

So what is the highest supported micro SD capacity for the Nintendo Switch?

According to Nintendo's support page on the topic:

The following types of microSD cards are supported on Nintendo Switch:

microSD (up to 2 GB) microSDHC (4 GB - 32 GB) microSDXC (64 GB and above)

Important: In order to use a microSDXC card on the Nintendo Switch console, a system update is required.

Also, they mention speed class:

Up to speed class 10 for the SD type (minimum guaranteed speed: 10 MB/sec) Up to class 1 for the UHS type (minimum guaranteed speed: 10 MB/sec).
