I purchased a Baraccuda hard-drive (model ST3000DM001) that supports a maximum read transfer rate of 210 MB/s and SATA 1.5/3/6 Gb/s. My motherboard has a limited number of 6 Gb/s ports so I'd like to reserve them for when it's really necessary.
When does a hard-drive benefit from a SATA 6 Gb/s port? Doesn't it require a transfer speed of at least 375 MB/s to surpass the limit of SATA 3 Gb/s? Are there any other benefits of SATA 6 Gb/s vs 3 Gb/s ports?
