USB Writing speed

Hello there!

SC Live 4 User, loving this standalone unit so far! Since I switched from a small small USB controller to this one, when trying to record a mix into the USB drive, I get error message that the USB is too slow to record a mix on it!

What would be the best writing speed for USB drive to record multiple mixes?

Sorry for such a beginners question, Have a great day!

Axe memory speedy + are the best and the fastest ! You will find it on Amazon. Try it and forget sandisk crap !
