Does the SDHC cards work as well?

Also does formatting the card to FAT32 change anything that would cause speed decreases or poor performance?

Just got a 64 gig Extreme Plus card by SanDisk & wanna know before I start tampering. Can't wait to see the class U-1 80MB/second speeds! Yet also wanna keep it ready to go for the X+1!!!

128 GB too

I've read on CM11 thread that 128GB cards are working as well. Can't beat the XT925...

Well last week I started to have problems w/ the SD and now the cell does not recognize it. I went back to the 16GB card. :( probably my problem is because the 64card it's a generic card...

I unlocked my bootloader and installed CM 11 just for use my 64 gigs sdcard but the phone can't detect it. I had a Droid 4 that worked wonders with the same card and ROM. Any insights?

The phone it's a Motorola Razr 925 and the sdcard it's a Kingston SDXC 64 GB and I trying to run it in CM 11 from herehttps://drive.google.com/file/d/0B6L4uLoMGODAdERyTmxtaVNwNTQ/view?usp=sharing

EDIT: I used both Paranoidhttp://xdaforums.com/showthread.php?t=2696606 and SlimKat http://xdaforums.com/showthread.php?t=2531983ROMS and my 64 gig sdcard is working without format

    Hi everyone, just wanted to confirm that 64GB MicroSDXC cards do work. I bought this one http://www.amazon.com/dp/B007WTAJTO/ref=pe_175190_21431760_M3T1_ST1_dp_1

    At first it will not work, but you must format it with the phone and it will work well. Reports 59.6 GB

    Saludos,
    Gustavo

    having tons of problems with mine; tried formatting in Windows (FAT32 with "guiformat.exe"), formatting in the device a few times...

    Every time, when trying to copy stuff onto the card from my Windows machine, after a few GB the connection just drops...and then the card doesnt seem to work properly until re-format. Everything is *extremely* slow to respond, even to the point of screwing with explorer when I open "Computer" in Windows from the start menu...

    Bad device? Bad card? PEBCAK?

    You probably got a dud. I would return it. Haven't had any problems like that here.

    believable- this is why I only buy Extreme Pro CF cards for my camera :p

    alas...the Extreme Pro line stops at 16GB for the MicroSDXC line, (perhaps thats a hint at the difficulty of reliably making rad MicroSD cards?) and I'll be damned if I have an Android with less storage capacity than an iPhone.

    Probably its a fake, do a google search about fake flash drives and memory cards and use the sugested program to test the card.
    Warning, it will be slow.

    Doubtful...sold by Amazon.com LLC. I don't buy eBay shiest unless I can't find it on amazon or somewhere that either accepts google wallet or is within driving/shouting distance. Still though, I took your advice and downloaded H2testw and will run the test tonight.

    Thanks for all the ideas guys!
