Spec Will Cut External Drive Power Cords 167
Lucas123 writes "The Serial ATA International Organization just revealed that it is well along the way to finishing a specification that would remove separate power cords to external SATA drives or optical disk drives, allowing them to draw power from the host system. The resulting new cable, being called Power Over eSATA, will be compatible with the existing eSATA connector and support the current maximum interface transfer rate of 3Gb/s. The SATA organization expects the new cables to be released later this year to drive makers."

USB? Firewire? (Score:3, Insightful)
As far as the article, it looks like a neat new development, but I know that you can get power over USB and Firewire. Maybe not enough for an external hard drive (I don't know), but IMHO it makes more sense to upgrade the power capabilities of universal technologies rather than promoting an exclusively hard drive-related format.

It might not seem important right now, but it might come back and bite you on inferior cables or when they crank up the rates again.
From a easy of use point of view, it is certainly silly.

Multiply it by 4 for sata and 4-8 for USB, and you would, however, have a noticably thicker motherboard (and/or separate PSU connectors and caps beside the USB and SATA connectors).
It's most likely not the cable that's the problem but the actual electronics that have to support the rated draw of the cable. Or worse, imagine having motherboards that dont support the rated draw and having users calling tech support with 'my computer crashed as I inserted my USB cupwarmer and the keyboard with LCD display and cooling fan at once!!!'.
You'd end up having to have a calculator to figure out what devices you could actually attach to your computer at any one time. Much as I'm loath to say it, I prefer the wallwarts over that.

Clearly you are a good engineer, and as every good engineer knows, it's all about trade-offs. If Tesla had his way, there would indeed NOT be a separate power cord for the TV.
Overall historically, we've made pretty good decisions about how to handle power. However, in the last 10 years I have been very disappointed with consumer electronics. Powering a device is a major requirement for anything we design, yet batteries still suck, wall-warts continue to proliferate, mp3 players don't charge via a standard USB port, and I STILL have to plug every last item into it's own special power cord, despite the inconvenience.

Connect Everything Over Ethernet (Score:2, Insightful)
If everything just used a simple, yet as it has been proven efficient protocol like Ethernet, then our lives would be much easier.
Oh, and Ethernet also has Power Over Ethernet for the hungry devices. I wait for the day when I will plug an RJ-45 jack into my hard drive (which will not be a hard-drive, but an SSD).
