Hey I was wondering if someone could tell me SATAIII are necessary for optical drives or will SATAII work just fine. I know a HDD or a SSD should be used with a SATAIII for optimal performance...right? Thanks guys

It is basically based on if the component is SATA3 compatible or not. A SATA2 device on a SATA3 connector works just like it was on SATA2 connector.

Well I was looking at my optical drive and it just says it's interface is SATA. It doesn't specify.

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
