what is the maximum size of micro SD card will support for RT?

SanDisk announced a 128 GB microSDXC card yesterday. gerbir21 has been said Surface Pro will do run up to 512 GB, any info updates on RT, anyone gonna try?

My SanDisk 128GB microSDXC card just arrived. It works in my Surface RT, Surface 2, and Surface Pro 2.

It comes formatted as exFAT, and gives 119GB of formatted storage space.

Greetings all,

Surface currently supports all MicroSD cards available in the market today and new cards will be tested as they become available.

I also have the SanDisk 128GB MicroSDXC and it works with Surface Pro and Surface Pro 2. I did have to insert the card and reboot as it did not auto-detect the card. Once rebooted, the disk was available. If you want to use the SDXC card to store any libraries, you will need to reformat the disk as NTFS instead of exFAT. Windows 8.1 and the SDXC card formatted as NTFS supports libraries such as pictures, videos, and music.

As for the life span, if it is like my 64GB card for the Surface Pro then it lasted for about 15 months before it started corrupting.

I want to get the biggest size card that the Surface will support, so is it the 32, 64, or 128 card?

Your Surface RT supports the highest-capacity microSDXC card available, which is 64GB.

If you need more space than that, you can always plug a higher-capacity flash drive or portable hard drive into the USB port.

I have a 64gb SanDisk class 10 on my 32gb original surface rt, and it works like a charm , theres no micro sd cards bigger than 64gb right now. So just go with the 64gb for now.

Yes it works perfectly. Class ten in fact is the best option.

Yes. You can use a microSD, microSDHC, or microSDXC memory card.

Sorry, I haven't tested it yet. I still need to buy one....

This MS support page mentions all three card types:

Hey Phil10101,

Surface supports MicroSDXC. We've tested up to 64GB. You can find the reference on this by going to Surface.com under Surface with Windows RT Specifications.

Kindest Regards,
