Mainly I just want to know what they have so I make sure stuff is compatible. My existing PC with the SSD I installed is impressively fast, and IIRC it's only SATA 2... didn't have SATA 3 back then or it cost too much or something.Don't get hung up on the interfaces. It's like a speed limit. Do you care if the speed limit is 55 mph or 75 mph when you're riding a bicycle? The speed of the drive is what's important, and with SSDs it's unlikely you'll notice the differences, they're all fast these days.
