Building a new pc and after ordering all the parts I realized my hd interface was SATA 3.0 GB/s and the motherboard only has connectors for 1.5 GB/s. I don't know much about hard drives or motherboards, but will that be a compatibility issue? Thanks.

To ensure seamless backward compatibility between older SATA and the newer faster SATA 3.0 Gb/s devices, the latter devices are required to support the original 1.5 Gb/s rate. In practice, some older SATA systems that do not support SATA speed negotiation require the peripheral drive's speed be manually hardlimited to 150 MB/s with the use of a jumper for a 300 MB/s drive.

So will the hd automatically adjust to the settings of the motherboard?

Most hard drives come already set to SATA 1 mode, which is the 1.5 Gb/s setting. Some of these you move a jumper to invoke SATA II mode, others you download a program from their website to turn it into SATA II. On occasion you can supposedly alter this from within the motherboard BIOS, though I've yet to see such an option.
