It's going to be very difficult to find a quad port SATA controller that does not have RAID capabilities built in.

That said, I would stay away from the smaller brands that don't have a strong reputation. I have used RAID from LSI Logic (now Avago) because they are the OEM manufacturer for some big names like Dell and Apple. In fact, you can get Dell and Apple branded RAID controllers to work in pretty much any machine; I have done so in the past.

For your application, you just need a simple quad port SATA RAID controller like the LSI Logic 9211-4i. Just remember, you will need the mini SAS to SATA breakout cable.

It's going to be very difficult to find a quad port SATA controller that does not have RAID capabilities built in so you might as well get it with RAID and just not turn on that feature. It is nice, however, to know that you can go RAID if you want to later down the line.
