Serial ATA for Mini Hard Drives Planned 105

Posted by CowboyNeal from the sata-to-go dept.
Lord_Slepnir writes "Cnet is reporting on a consortium of companies that wish to develop a Serial ATA hard drive interface for Miniature hard drives called CE-ATA. The goal of these new drives would be to cut power consumption and use smaller connectors, not to provide an increase in speed. 'The purpose is to design a new interface tailored to the consumer electronics and handheld gadget segment,' said Intel's principal engineer for CE-ATA, Knut Grimsrud. The consortium consists of Intel, Hitachi Global Storage Technologies, Marvell Semiconductor, Seagate Technology, and Toshiba America Information Systems."

    Surely there's a limit as to how small you want everything? WIth mobile phones now being credit card sized [pcmag.com], isn't there a limit when it's too expensive and time-consuming to make already-small things even smaller for the expected returns? Or is it just a case of "mine is smaller than yours!"?

How many SATA drives used molex connectors instead? So no big deal! I don't see why we need yet another standard; it's bad enough to see SATA2 and SAS coming down the pipe already.

      I assume that by "use smaller connectors", they meant that SATA is smaller than the connectors currently being used in mini hard drives. While power usage may be limited more by the drive itself, size may not be. Take a look at the currect standard for 1 inch hard drives. It needs 52 pins on it. SATA in contrast, only needs 8, plus whatever is needed for power.

    It would be a good point to note that only the more recent releases of the Linux kernel suport Serial ATA.
    I recently assembled a PC with a IBM-Hitachi Deskstar SATA hard drive and Redhat 9 would not recognize it. I then downloaded SUSE Personal edition 9.1 and I had no problems installing SUSE Linux. However, I need a Linux distro with more bundled software than what the SUSE personal edition provides. As I post this note, I'm downloading Fedora Core-2. I hope that Fedora Core-2 recognizes my SATA drive.
    I found very little information regarding Linux SATA support on the web. I also posted some questions to comp.os.linux.redhat and got no replies.

      SATA *does* specify a standard for a power connector and location (most still have the standard ATX power connector). You could feed it through the same cable through the motherboard in theory, though that would increase the power draw of the drive controller significantly. This is mainly for the possibility sane backplanes (including longer ground pins than other pins for hot-swap capability.)

      • Also, the part about the motherboard being able to unplug the controllers is pointless, and dangerous, unless coordinated via the command channel anyway.

        Being able to send a 'turn yourself off' command is nearly as low power as actually unplugging it (for example, do you have to unplug/remove batteries of most of your electronics when not using them, or can you just hit the power button to have themselves turn on, and do those electronics have significant power draw in their standby state?).
