Very nice. You could store 29 days of everything transitted on Freeview (23 after switchover). Moore's law says you're going to get it in a 36TB in a single drive in five years though... 2009/9/2 Ian Forrester ian.forres...@bbc.co.uk http://blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-to-build- cheap-cloud-storage/ Found via Frank Wales, I'm amazed, but this amazed me when I first saw it too - http://www.youtube.com/watch?v=96dWOEa4Djs Secret[] Private[] Public[x] Ian Forrester Senior Backstage Producer, BBC RD 01612444063 | 07711913293 ian.forres...@bbc.co.uk - Sent via the backstage.bbc.co.uk discussion group.

Hmm, not sure it doesn't doesn't Moore's law actually say that the density of transistors will double every 18 months? Alex On 3 Sep 2009, at 09:08, Brian Butterworth wrote: Very nice.

Re: [backstage] Warning: Super geeky - Petabytes on a budget
The first hard drive we had a school was a Winchester for the BBC Micro network, it was a full hight 5.25 drive, and it had a capacity of 10 megabytes. By the time I installed servers when I was a BT Broadcast, server drive were half hight and in the 3 size, with capacities in single gigabytes. I popped a terrabyte in a server a few weeks ago, bought from PC World (boo! hiss!) in the half hight 3 size. Whilst I have a laptop drive under one of my monitors that is smaller, most drives still are half hight 3. I hold that experience suggests that you can apply Moore's Law to hard drive capacity as well, and it seems reasonable that there will be no move from half hight 3 drives. Moore's law, in the basic form double the stuff for the same price in 18 months applies to hard drives, and it works with broadband and other communications speeds. The only thing it doesn't work for is data compression and broadcast networks. I'm sorry if you think this is a misapplication of Moore's Law, I was just trying to make a general point. 2009/9/3 Rhys Jones r...@highfiddletea.co.uk Sorry, the Kryder's Law link should be: http://www.mattscomputertrends.com/Kryder%27s.html 2009/9/3 Rhys Jones r...@highfiddletea.co.uk: Quite - I'm not aware that Moore said anything about the density of magnetic storage!

Re: [backstage] Warning: Super geeky - Petabytes on a budget
I know you were just making a general point, I'm just being pedantic :-p Moore's Law itself is strictly the defined in the original paper about it, although most people do generalise it for application to other things... Moore's Law, in it's original form, still holds and is predicted to hold for at least another 10 years. The increase in HD capacity has apparently slowed over the last few years and is no longer holding to a similar pattern.
