RAID 0 Array Showing Smaller Size Than Expected?

[jb7]

I have a 500gb and a 250gb Samsung 840 SSD's.

I have created a raid 0 array in my motherboard's bios, however the total size of the array is 465 gb (I've definitely selected raid 0, and not raid 1)

Any ideas? It doesn't seem to be using the second drive....

Thanks!

Forgive me if I'm wrong, but if you're using two different sized drives in RAID 0 then you're only ever going to get twice the capacity of the smallest drive, which, after formatting, is roughly what you have.

The RAID is writing half the data to your smaller drive and half to your bigger drive, so only using about half of its capacity. You can't set it up to write 2/3 to one and 1/3 to the other.

Ah I see! Thought it worked with any size drive

Oh well, I'll keep the OS on the 500 and games on the 250
