What is the maximum NTFS volume size supported on a GPT disk?
This depends on the cluster size that is selected at the time of formatting. NTFS is currently limited to 2^32-1 allocation units. This yields a 256TB volume, using 64k clusters. However, this has only been tested to 17TB, or 17,592,186,044,416 bytes, using 4K cluster size. The following chart shows the NTFS limits based on cluster size:
