The first drive has a read speed of 500 Megabytes Per Second. The second 535, so only slightly faster. A sata iii Hardware Interface works with a sata iii controller that supports a max bus speed of 6 Gb. See https://en.wikipedia.org/wiki/Serial_ATA The first drive is actually a sata ii drive, the second sata iii. The term "Style" has no technical meaning. It's just a marketing term. The hardware interface speed tells you whether it's sata, sata ii, or sata iii. Newer drives are often lower in price per MB than older ones.
