Maximum partition size: 16 TB (terabytes) for volumes formatted with a normal 4096 byte cluster size. Larger cluster sizes will increase capacity; smaller cluster sizes will decrease capacity (e.g. 2 TB maximum for a 512 byte cluster size).
NAS (Network Attached Storage) drives cannot be defragmented, and are not displayed in Vopt's drive list.
