RAID 0 failed - which disk?

I have two crappy HDDs in RAID 0 that I use for video recording. They are of differing models but both are 500GB Seagates.

It has been acting up for about a week and today it died completely. However, which disk failed? It isn't giving me any indication in the RAID setup program other than a 'failed' status.

They both show up in windows disk management and the both seem to work independently and can be formatted and everything, scanning them individually shows nothing wrong with either but I am 100% this is not the case, one of them is busted. The SSD is the boot drive, the other is one of the disk in RAID, the other is not shown. Here is a terrible screenshot of the BIOS RAID program.

Is it the one that isn't listed? I just don't want to waste time trying to figure it out by randomly replacing them only to be the wrong one.

One that is listed in the srceencap is considered good.
Other one (not listed) is considered missing. Did you connect it to different sata port on the motherboard?
If your motherboard has multiple sata controllers, then moving drive between them might break the raid.

Nah I didn't do anything except look at that info page. I wanted to take a pic so I can compare serial numbers to identify it.
 
It appears to be the one that isn't shown as you said. I filled the other with data a few times to make sure it didn't freak out. I checked the SMART attributes with Seatools and it says the bad one is fine, and windows says its fine, but once you start writing data to it though (about 20GB) it goes offline with a cyclic redundancy error.

Thanks for the assistance.
