I'm thinking of building my first system and I've already come up with a question.

If a motherboard supports both SATA and IDE/PATA peripherals I think I understand the advantages of a SATA hard drive, but is there any advantage to SATA optical (CD/DVD) drives?

Thanks.

The same advantage as any other SATA device vs. PATA:

1. faster transfer rates (SATA II - 300 MB/sec vs. Ultra ATA/133 - 133 MB/sec)
.......The newer SATA III drives advertise a 6GB/s transfer rate
2. better airflow through the case, due to smaller cables
3. less power consumption (250 millivolts vs. 5 volts), so less heat generated, resulting in longer component life

Thanks, tg1911! I knew about the speed, but I always burn CDs and DVDs at low speeds -- I've had a lot better luck getting playable discs that way. So, I wasn't sure there's be any difference.

The power issue was the piece I missed!

I am just not that sure about that point.

This is just what I read a while back, and had it bookmarked:

If it's wrong, I want to know about it.

I have a friend who has had multiple PATA drives. He has had several in the last three years but they kept failing. Only recently did he decide to go with SATA. We'll see what happens.
