Sorry if I didn't explain right... again, the "lingo" is unfamiliar to me. I am NOT getting the (faster, better?) SATA internal hard drive at this time. In part due to $$ and the need for the additional "card" to make it work, etc. I am getting the other one... I think it is called "PATA"... even though it may not be super fast, it will be a huge improvement over my puny, tiny 27GB hard drive that I have now, the one that came w/the Sawtooth when I bought it, used, years ago. It's really the additional hard disk space that I need right now, and at a bargain-basement price! Thanks, Michelle
