"The best cluster size is normally the one that is automatically suggested by the format dialog. This is at least as large as the size of the hardware sector, which is the atomic read/write size.

Using a larger sector size will mean that the O/S will need to issue multiple read/write operations to the driver to write it out or get it into memory. Using a smaller size is even worse (as I never tried I don't even know if it's possible).

Conclusion: If the Passport USB is already formatted in NTFS, don't worry. Otherwise, let the O/S decide."
