Allocation Unit Size for 64GB MicroSD card?

[Jerenny]

Hey guys, so, I have this particular MicroSD card for my Shield Tablet - http://www.amazon.com/SanDisk-Memory.../dp/B00M55C1I2

And upon formatting it to NTFS, I realized an option called Allocation Unit Size. I see it go from 512 bytes all the way to 64kB.

Any idea what I should choose?

Just use 4KB (default). Windows/NTFS will try to align writes when reasonable to larger values, so you really don't gain anything by trying to match it to a likely-larger page size (which you may not be able to do for TLC, anyway).
