Serial ATA for Mini Hard Drives Planned

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."

    The comment about 2.5" not using 12V related to my comment that putting in 12V would add another layer. Because 2.5" drives don't use 12V, you don't need to route 12V.

    Trace size is mostly based upon amperage. Energy density does matter, but I don't know at what level it becomes a problem.

    Anyway, I assure you your motherboard doesn't have a 12V layer right now. They use as few layers as possible to save money. Intel made the 865 chipset work with a 6-layer motherboard. You think 1 of those 6 was 12V? Guess again.

    Additionally, you aren't just talking about putting power into the motherboard, you're talking about distribution through the motherboard. Why doesn't your motherboard already have 12V coming out to the drives? It has 12V going in at the power connector, check the ATX spec.

    Why? Because powering 4 drives (or 6 on my mobo!) is a lot of power. Your power lost in the motherboard (turned into heat) is R * the current of 6 drives. This is why power supplies have multiple drive power cables to start with, and not just one strand with all the connectors on it in a row.

    And your suggestion for budget system only makes sense if you accept that your proposal is a given. But it isn't. The current system costs even less than your proposed low-cost solution. That's why it'll be around for quite some time.

      Anyway, I assure you your motherboard doesn't have a 12V layer right now.

      So you throw a .25" trace on one edge of one layer to distribute the power to the drive connectors. It's not like you need to put the connectors in random places all over the motherboard.

      Why doesn't your motherboard already have 12V coming out to the drives?

      Because the spec doesn't require it. Why do you think that laptops provide +5V to the drives? Because the spec requires it.

      Why? Because powering 4 drives (or 6 on my mobo!) is a lot of power.

      All six SATA drives seeking at once would be about 6.5 amps. That's not a lot of power.

      Your power lost in the motherboard (turned into heat) is R * the current of 6 drives.

      When we have 2.4ghz Pentium 4 CPUs that draw 49.8 amps, it's hard for me to get excited about drives that draw about 1 amp (or 3 at startup).

      This is why power supplies have multiple drive power cables to start with, and not just one strand with all the connectors on it in a row.

      It's really so that the 12V at the first drive doesn't turn into 11.3V at the last drive. It's keeping the voltages the same throughout.

      And your suggestion for budget system only makes sense if you accept that your proposal is a given. But it isn't. The current system costs even less than your proposed low-cost solution.

      Sorry, but I don't buy it. I don't believe that doubling the number of connectors and cables for each drive saves money in parts or labor, nor does it contribute to reliability.

    I suggested this to the SATA forum a few months back, I wonder when they started working on it. The crux of the problem is this:

    Existing flash memory formats aren't fast enough, small enough, or standard enough. CF is fast and standard but the connector is bulky. XD is fast and small but nobody has XD slots on their desktop. SD is small but not too fast or standard. And of course the 44-pin laptop hard drive connector is downright huge compared to modern pocket devices. The advantage of all these memory formats is driverlessness.

    USB, USB2, and Firewire suffer an opposite problem: The interfaces are standard and fast, and the connectors are small, and include a power supply. Trouble is, there's no physical form factor standard for USB keychain memory. You can't build a camera that'll securely nestle a USB keychain inside, because none of them are shaped the same. Teaching a portable device to control a USB mass storage device is also nontrivial, because being a USB host is a pain in the ass.

    SATA could fill this gap, by defining a physical size and shape for devices to fit into. The devices are "dumb" in that they require no drivers, the interface is plenty fast enough for any portable device, and here's the key, so to speak: Desktops are already starting to include SATA ports up front, for external drive attachment. Being able to plug your portable's memory cartridge straight into your desktop, or your laptop, would be great.

    Sony was one step away from this with the Memory Stick format, in that all their laptops started including MS slots soon after its release. They betamaxed the proprietary format for too long though, and it never gained wide adoption. Desktops don't have MS slots, and it's only Sony devices that use them anyway.

    If I worked for a digital camera maker right now, I'd sidestep the whole mess by releasing my own line of USB memory keychains, perhaps in a marketing deal with Lexar or Sandisk. They'd be functionally identical to current designs, but physically shaped to fit into a recess in the camera. (Even better, I'd build my camera to accept the PQI IntelligentStick as native memory, and capitalize on the existing market base.)

    It's small, it's fast, it provides power, and PQI is already selling the media. Desktops and laptops already include the port, so there are no readers to mess with. The physical size standard is all that's missing.

    So how about it, manufacturers? Sign a deal with PQI that says they won't change the physical shape of their stick. Start building music players and cameras to take the format. (Ooh, good thing I looked it up before hitting Submit. PQI has this on their site: "Our I-Stick can go straight from your digital still camera, PDA, or MP3 player directly into the USB port on your laptop or workstation CPU.".... really? I'm not aware of any such devices that currently accomodate the stick. What am I missing?
