12PB [or 12,000TB - remember 1TB = 1024GB before formatting] / 18GB is a satanic 666,666 hours of completely uncompressed 1080p.

[or if James Cameron has his way, 12PB will store about 2,500 hours of 60fps quad HD 3D Avatar nonsense].

here's an idea of where video bitrates are heading: http://bit.ly/goBzat

blu-ray is a highly compressed format. 5MB/s is highly compressed compared to uncompressed 1080p 24fps, which is 95MB/s for 8-bit color and 127MB/s for 10-bit color. This is 334 or 445GB/hr. Yeah Blu-ray is pretty damn compressed.

Even if I use a very conservative estimate and say Apple offers the same storage as Amazon (20 GB per person), 12 petabytes is only serving 600k people.

If this is for iTunes then it is mostly for the store. Which just needs to host files for users to download/stream copies of.

Also it's a bad idea to assume that Apple is going to do the same as Amazon. They likely won't. It will be 20gb for the current cost to be shared across all systems or knowing them they will say that most folks only use 5-6 GB of space so they are dropping the price down to $49 with only 5-10 gb of space per person across all systems

Yeah it sounds a little on the low side for personal data. I mean.. 20GB.. That's like my iphoto library. They'll probably be adding more space as it becomes needed though. Very exciting though, nonetheless!

how many drives and how much space
mobile me is world wide
itunes is "world wide"
maybe this is just first installment
how much does netflix and amazon have

doesn't tell much only that apple is close to opening the data center which has been discussed many times before

like i said before---someone drive by the data center open trash bins count boxes

I'm surprised that I'm the first person to point out the following:

Isilon provides highly-scalable RAID-based storage arrays. While the USABLE storage might be 12 petabytes (which is absolutely massive by any measure), the arrays are setup in an array of striped or blocked storage with parity and/or protection discs (depending upon the RAID method used, such as RAID5, RAID10, etc). Typically it is about a 1.3 X to 1.5X factor above the USABLE storage that ultimately comprises the actual raw storage, spread out across many redundant discs.

Point is, that arrays are not measured in RAW storage but USABLE storage. The amount of storage composing these arrays is probably closer to 18 petabytes, if not higher, depending on the RAID method employed.

Again, for those that are saying that even 12 PB is not "impressive", I have no idea where you are getting your benchmark. It is absolutely friggin' HUGE, and only compounded when you consider the additional protection overhead which takes the figure even higher.

The last mile. Say it with me.

Should be the same fun same-old with the telcos and ISPs as their systems sag under the load.

Enjoy not being able to see a difference between 720 and 1080. I can.
