I really want to confirm if a pair of 2TB internal desktop bootable drives, configured in RAID 0 is possible with a chipset that doesnt support UEFI?

Thanks
 
no it will not work. booting with +2TB is past the limitations of MBR, it requires using GPT, and to boot a GPT partition requires a UEFI enabled system.
 
Are you sure, since I think the MBR limitation is with the drive itself and not the total volume.
 
Unless you have a UEFI board, you are limited to MBR which is limited to 2.19TB.
 
How would I be exceeding the MBR limit if each drive is under 2.19TB?

I remember doing this about a month ago and the 4TB showed up fine in thre RAID BIOS but not in windows. I'm almost positive that I didn't install any window updates including SP1. I pretty much just configured the drives for raid, installed the OS and went to my computer and saw that the C: was only aound 1.99TB. Right after that I pulled out one of the 2TB drives and just used the one.

I just want to be 100% certain that the drive wouldn't show up as 4TB in windows even if I installed all the windows 7 updates, including SP1?

I have a nforce 650 sli chipset and almost sure it doesnt support UEFI.

Unless you are running a 64 bit varient AND have a UEFI based system, you have a 2.19TB boot volume limit (however you decide to achieve that. 1 2TB disk, 2 1TB in R0, etc). If you want a larger boot volume, you need a new Motherboard that supports UEFI and a 64 bit Win7 OS. Your board DOES NOT support UEFI.

True for Windows but not all OS's.

Also Areca could do this up to 16 TB by using larger sector sizes. Not sure if your onboard raid can do that or not.
