Default [Q] Is it fine(OTG USB Question)?

Sorry for my Strange English
I bought a otg usb for my nexus 5
I am using 32GB Model. However I am really hard user so I bought 32gb otg usb.
I formatted it(ExFat, 32KB)
I disappointed with the speed.
So I installed ElementalX 0.29-cm
and formatted my usb again(NTFS, 2048B)
Is it fine?(Please see the screenshot file attachment)
