Will win7 64 recognize 2 2tb hd in raid 0 4tb

The disks would need to be GPT rather than MBR and you need an EFI BIOS to be able to boot from a volume this size.

Better if you create a 1TB partion for the os/ and the rest for data, then W7 should be ok to boot.

I don't believe that the drives will show up as 4TB is RAID0 - they would show up as 2TB if you had them in RAID0.

Also, I'm sure you've read on RAID0, but if one disk fails, all the data will be gone from both disks.

Might I be able to ask why you want RAID0 on 2 2TB disks? Is there money for a SSD - I think it would give you better performance...then you could use those disks for storage.

Thank you
I have a g1 sniper motherboard and ended up MBR the two 2tb green hd in raid 0 on the 6gb/s sata conn of the motherboard it sees 3.7tb in win7. lost about 300gb , good enough. use for running games and storage.
i have two xm25 intel 80gb ssd running in raid 0 on the 3gb/s sata conn of the motherboard 160gb boot drive loads win7 in 9 sec i also use this drive to run all my primary software, adobe an such.

i was not sure if win7 would see the whole 4tb and after making the raid 0 in win7 it will only see 3.7tb.

My apologies...it was early when I must have been reading...I think I was thinking RAID1 not RAID0.

Happy you got it working. I'd still be worried about RAID0 for my own data, and doubt the performance would be that great, especially on Green drives, but if you're happy, all the better.
