Will this RAID 0 work?

I'm thinking of making an ATA RAID 0 with two hard drives.
I already have one *ATA* drive, which has about 50 MB/s transfer rate.

If I use two of them (on a PCI RAID card), will my transfer rate double to 100 MB/s?
 
Theoretically, yes. I don't know exactly, but I would assume the RAID would go only as fast as your slowest drive. So, if your new drive gets 33Mbps, then you'd probably get 66.

Yes, sequential transfer is the target. This will be a scratch drive.
I'm hoping PATA will be up to the task. Most articles on RAID 0
seldom mention how the PATA interface impacts it. I'm worried that
RAID 0 was meant for SATA interface.

RAID0 was around long before SATA was even invented. However, you will most likely have to use a software program to do it, since I do not know of a motherboard that supports hardware RAID for IDE.
 
I like to stick to Highpoint or Promise just for quality vs. value. There are others, of course, but those are my favorites.
 
it all depends on the size of the stripes that you enable and the size of the files that you plan on reading... and the amount of files at once. it should theoretically double to 100mbps but it'll probably be between 60-80mbps instead... which is still a lot better... thats like saying instead of taking windows 20-30 seconds to load it'll take 15-20 seconds to load. its still a really great improvement.
performance of the hard drives matters too, and raid card performance as well. not all raid cards are the same... most are integrated in the motherboard for the average home user.

I have provided two reviews now in these forums that both confirm that RAID 0 does not improve performance that much, if any. They do say that it isn't worth it for the desktop in fact. Would you care to provide one to the contrary?

I did read RAID 101 before posting. I too don't think general performance will be affected. I want RAID 0 only for video capturing. A very temporary storage.

The ATA disk I have right now can sustain 50 MB/s, which would make me think it is enough for capture data rates of only 20MB/s.

But, something is not right. I thought I cured my frame drop problems, but they are back. My source now is not as clean as before.

Strange thing is that a clean source resulted in no frames dropped on an HDD with only 40 MB/s. Now, with more noise in the video signal, frame drop is very common on 50 MB/s HDD. Why?!

The only thing that I can think of is that the frames change too quickly for something to keep up. But what? CPU usage is only 50%, so that can't be it. HDD write rate is 50 MB/s, so that shouldn't be it either. Or can it?
