MPC Lagging/Freezing with 32gb CF Card

Sup all, I just got this memory card
https://www.amazon.com/Toshiba-EXCERIA- ... B00KB45JKQ

It's supposed to be one of the fastest cards, but for some reason, my MPC is slow when loading folders and sometimes freezes when playing samples. It was pre-formatted to FAT32

I am using JJOS 3 free.

I can load some stuff but it's very slow. It seems to be working just very sluggish. The previous 4mb card I have works faster but is slower in specs. I know there's a limit to the amount you can use but there has to be some way to make this work. Anyone help please? Thank you!

I have the 64gb version and it freezes both of my 2500s. I have tried to format in the MPCs with no luck, I think there may be a compatibility issue with these cards. Any others out there have experiences with the Exceria?
