Hello, do you know what size drive I can have in my system, the motherboard is a z77extreme11 Asrock board. I'm trying to find out the max size I can have internally, will the system recognise 4TB internal drives, 8TB? Thanks

The drive needs to be formatted in GPT as opposed to MBR. MBR is only good for drives 2GB or less. Over 2GB requires GPT format.

(In order for an operating system to fully support storage devices that have capacities that exceed 2 terabytes (2 TB, or 2 trillion bytes), the device must be initialized by using the GUID partition table (GPT) partitioning scheme. This scheme supports addressing of the full range of storage capacity. If the user intends to start the computer from one of these large disks, the system’s base firmware interface must use the Unified Extensible Firmware Interface (UEFI) and not BIOS.

EDIT:
you won't be able to boot to a large GPT drive unless you also have a motherboard running UEFI.
