Hi, I have a motherboard that says it supports data rates of 300MB/s, and i want to buy a sata hard drive that says that it does 3Gb/s, will they work together ok.

Yes know what the capital B and the lowercase b means for bit and byte, so dont worry

Hi,
Yes it will work, they (300MB/s, 3Gb/s) are essentially the same thing.

3Gb/s = 375MB/s but the SATA standard uses 8b/10b encoding which means that it will take 10bits to transfer 8bits or a byte of data. Hence
the real transfer rate capability is (8/10ths of 375MB/s) or 300MB/s.
The actual hard drive capability limits the rate at which data is transfered to below that of the bus so SATA is not the limiting factor.
