3x80gb one platter vs 2x160gb two platter, which is quieter?

I will set up a RAID 0 with Samsung Spinpoint drives. Using 3 drives instead of 2 makes it up to 50% faster than with only 2 drives, right? Three SP0812C (80gb) drives is the same price as two SP1614C (160gb) drives, and you get 50% extra speed for 33% less storage space.
I have read that 2 platters give 1-2 dB more noise than 1 platter, and 2 drives give 3 dB more noise than 1 drive.
So with three 1 platter drives it would be -6 dB more noise?
And with two 2 platter drives it would be 4-5 dB more noise?
Maybe I should get three SP1614C drives instead of SP0812C, then it would be 1-2 dB more noise for twice storage space but 50% more money, but I don't think I need that much storage.
I already have a SP1614N and it has an annoying whine but I can take it, it is much better than my old WD1200JB, I can't stand it for 5 mins now (whine goes through earplugs).
Two SP0812C would be the most silent RAID 0 solution for me with only 1-2 dB increase in noise from what I have now, but it would be 30% more expensive than a SP1614C with the same storage space, but I would get a 100% increase in speed.
Adding another 3 dB for a third drive for only 50% extra speed is probably bad.
2 port SATA RAID controller cards are cheaper than 4 port, so I would save some money there (almost half price). I also need extra cables for more than two drives.
Does the price of the RAID controller matter, can't I just buy the cheapest one? If I only use RAID 0, then I don't need support for other RAID 5 or 10.
So it would be best to buy either 2xSP0812C or 2xSP1614C.
I want the best bang for the buck, but noise is most important. What should I do?
