Serial ATA CD-Rom Drives?

Posted by Cliff on from the when-will-the-market-catch-on dept.

OutRigged asks: "With Serial ATA hard drives starting to go mainstream, and being almost equal in price to their parallel equivalents, one would think we'd have Serial ATA CD-ROM drives by now. Yet wherever I look, all I see are PATA based CD-ROM drives. It's obvious that an optical drive will benefit little, if at all from using SATA, but why not switch for the sake of the cable size? CD-ROM drives are usually at the top of the case, and with the 1m limit in length, along with the small size of the cables, I see no reason not to use a Serial ATA interface in a CD-ROM drive."

    You can now get a cdrom for 10, cdrw for 20... The cost of developing a new product in order to sell it for 5 more is just not worth it.

  3. Re:Internal Firewire? by Paladin128 · · Score: 2, Informative

    Though the raw bandwidth of FireWire is great, it has greater latency than SATA or PATA or SCSI. It's an external standard, and has support for things like multiple devices per channel and hotplug. This ads overhead to the data transmitted. Firewire is inherently superior to USB for storage, but not to the other internal standards. SCSI and SATA2 also support ordered command queueing, which ads to performance on multi-user systems.

    Plus, with drives today, SATA's "mere" 150MB/s will never be saturated.
