Attempting to RAID 0 two SSD's

[akizzle]

I'm using a ASUS Z77 Sabertooth Motherboard and currently had 1 Mushkin 240GB ssd and a Lite-On 128GB ssd.

My original setup was the 240GB SSD running all my applications games holding all my music pictures and such. When I noticed I only had 4GB free a friend gave me his Lite-ON 128GB SSD to use.

Now when I go ahead and RAID0(stripe) it through the RAID Config it only allows me 238.5GB to use and I'm baffled by it. I should get over 300GB of disk space.

If anyone can help I'd greatly appreciate it.

A RAID array's total capacity is based upon the drive in the array with the smallest size.
So if you have a 128GB drive and a 240GB drive in RAID-0, you're array's size will be 256GB (128 x 2).
256GB after formatting equals 238.08; so your capacity is correct.

Thank you for clearing that up for me. Much appreciated.
