NO............6Gbs SATA is NOT needed for optimal performance :
- for any Optical drive ever made
- or, for any hard disk ever made
The ONLY device that currently comes even close to saturating a 3Gb/s SATA is a top of the line SSD.....
- most SSD aren't fast enough to need 6Gb/s, just a FEW of the fastest will benefit from it....
- if your not above about 250MB/s read or write speed you will gain zero (0) from 6Gb/s SATA
Here are the specs:
150 MB/s 1,200,000,000 150,000,000 Computer data interfaces SATA 1.5Gb/s – First generation
300 MB/s 2,400,000,000 300,000,000 Computer data interfaces SATA 3Gb/s – Second generation
600 MB/s 4,800,000,000 600,000,000 Computer data interfaces SATA 6Gb/s – Third generation
