Hi , I have recently installed a new seagate barracuda 1tb hard drive. I want to use it for storage for my game recordings but the write speed when I test it is coming in at 20 mb!, I have exact same model of hard-drive as my primary one and get write speeds of 150mb. Is it because my primary is connected to a 6gbs sata where as my new one is connected to 3gbs sata?. I only have one 6gbs sata available on my motherboard , any help would be appreciated
