6 TB WD Drives In X99 Running On-Board Raid 10

[sldwaa]

I am building a new PC and have selected either the MSI X99S XPOWER AC LGA 2011-v3 Intel X99 motherboard or the ASUS X99-DELUXE LGA 2011-v3 Intel X99 motherboard (leaning toward MSI), and will be using the i7-5820K processor. I have a question concerning the HDDs I plan on using and I am hoping someone can help me out with before I order the motherboard.

System HDD components:
- Crucial 1TB M550 SSD for OS running Windows 7 ultimate, 64 bit
- Four Western Digital Red 6 TB drives for storage running on-board raid 10

The question focuses on the four 6 TB red drives. Will the board / bios be able to handle these in on-board raid 10 (I do not like on-board parity raid (5) - I plan on using on-board raid 10 off the motherboard). In the old days, I think HDD drive sizes were capped at 2TB but have since increased. If I understand it correctly the two ways to get above this are either GUID or UEFI.
Will this matter, or am I way off base and this only applies to the OS drive with the MBR? BTW - I considered a NAS box, but that is another $500 for the Synology DS415Play I don't want to spend at this point as I do not stream much and having the files local on the tower case works well for me.

Any comments on the 6 TB reds and raid? Also, any other comments would be welcome. Just want to make sure I will have no issues with these bad boys in my planned configuration.

Thanks!

UEFI BIOS with GPT format on the drives. No other way to do it that I know of to get beyond 2TB in a single partition.

I have a pair of 3TB WD Red in a old HTPC running FreeNAS. Having them internal will just be that much faster.
