Making a "Multiple HDD" External Hard Drive

Hi,
      I've recently come across an idea and I would like some help on it.

I remembered I have 5 2.5' HDD (SATA) with 120/80 GB and I started thinking if there was a way to connect those HDD's together in a "chain" and creating one big External Hard Drive with one USB port connecting to the computer. It sounds a bit impossible to me but maybe some of you know of a way or similar type of system that I can work with?


Please help.

Thanks!



I didn't find the right solution from the Internet.
