which RAID card...?

I need advice about RAID cards...

My uncle wants to boost his hard-drive setup
I built him a new good-spec PC but he didnt buy a new HDD..
he just used the IDE 80Gb 8Mb cache one sharing the DVD-RAM IDE port

now he wants faster....
we want to setup 2 x SATAII drives in RAID O ARRAY but I dunno where to start with RAID cards that support SATAII..

he has a PCI-E x1 slot spare (as im aware in plugs into that)

any advice would be greatly appreciated...please and thank you

 

Personally, I like Adaptec among a few other brands. On Newegg you can find some cheaper models if this card is out budget, relatively easy to find.

Here's a Newegg link - just make sure when looking that it is PCIe x1

I use this one at work and have had no troubles with it at all.
