ExFAT or NTFS for Windows 10

[JRandyF]

I just purchased the new model My Book 4 TB USB 3.0 external disk drive. It came pre-formatted with ExFAT.

My understanding is that ExFAT was designed specifically for USB drives, but that Windows NTFS offers greater reliability.

Should I reformat the new drive to NTFS?

If so, should I use Windows 10 disk management or the WD Quick Formatter?

If you have no need to share the disk with a Mac, then I’d probably switch to NTFS… ExFAT is cross-compatible with lots of different OSes, but has exorbitant overhead if the cluster size is large.

Thank you for the quick response. Will reformat it to NTFS.
