128GB is the maximum size that the Cube's onboard ATA interface can recognize. If you put in a bigger drive, only the first 128GB will be recognized. Note that there is software that will allow a computer such as the Cube to use a bigger hard drive. See: http://eshop.macsales.com/item/Intech%20USA/SPEEDHCCD/ as an example.
