Power savings?

Write once, read never...maybe? Seems all about power savings. Having to spin up a drive or keep an array up for an unlikely access seems unattractive, however, the read latency for the cold flash would only need to be on par with HDD access times. To the extent that the MTBF of HDDs is a function of simply being powered and spinning, cold flash could increase longevity if it remained unpowered except in the rare ocassion where access was necessary.

I wonder if PCM would be a good candidate.

This is the one I have:

http://www.qnap.com/en/index.php?lang=en&sn=822&c=351&sc=514&t=523&n=3377

I chose it because they have a good reputation and support. Western Digital and Netgear have similar products but only trial SW bundled (last I checked). Mine's been running over 2 years without a hitch and is set up with 2 hard drives and what they call RAID 1 which means each hard drive is a mirror of the other so if one fails you can replace it and not lose anything.

Any link or suggestion what these devices could be. I use firms like Dropbox but they are cloud storage companies and not hardware systems.

I do hope this changes the industr. Facebook is an industry of itself. So markets can react to take advantage of this clear need. I think in the near future, storage will be a huge business area. Everyone must be ready for it as we generate these tons of data.

I think the leadership team of Facebook is becoming business savvy and forcing on profit.  The excitement is over and they realize the there is competition out there.  Therefore,  they realize that they need to cut cost and still maintain good service.  This is very smart.

how much space or power on a flash chip is actually dedicated to the block-erase process?  if flash were simplified to a be a purely write-once media, would it really change the power or density pictures?  I'm not sure the argument even stands if it's only directed at packaging: flash systems need a lot of channels to produce decent write speeds, even in the absence of overwrite (erase).

afaikt, the only thing that would change is that flash controllers could become dumber/smaller/cooler.

For a modest fee you can buy an internet appliance that has an integrated web server and can hold all of your photos and you and your friends can access them any time and you don't have to worry about FBook not caring

The space shuttle was just such an airliner, I read an article that said that without the 3 flight computers it couldn't be flown. Another examplke is the FA18 that is aerodynamically unstable. This allows it to do high speed manouevers because it does them naturally but I digress
