RAID on single SATA Port

Here's the thing:

I got a couple of SSD (80GB) that I wish to RAID (I don't have experience in RAID) but I don't have enough SATA port. 4 SATA port (SATA1 - SSD, SATA2-4 - HDD). I'm willing to remove my SATA1 SSD to add in the 80GB SSD I just got but I was wondering:

You can RAID across SATA1 - SATA4 (normal RAID, I believe). Is it possible to branch in and RAID into a single SATA port (SATA1 to 2 SSD)? The reason I'm trying to do this is not really a performance thing, just want to make full use of my new SSDs and if can, expand the capacity (by RAID). I google this and got some kind of SAS cable to branch out to 4 SATA.

Just guide me on how to tackle this dilemma. I rather not waste the other SSD and my HDD are big so I don't wish to take them out. I'm using SSD as the primary OS storage because it's faster. I checked out about this PCIe RAID controller option but it's hard to come by so I'm looking for this option.
