If I wanted to have 6.1 petabytes of storage space...

post #1 of 28
Thread Starter 
...how would I go about building it, and what would it cost to do so?

Depends what speeds you want out of it.
Could be cheap or very expensive.

Here is how I would do it.
Buy a bunch of NAS servers, Or old routers with USB and DDWRT support.

Get heaps of 2tb external drives, They go for about $80 each.
1pb = 1000tb

So would need 500 drives per pb.

500 X 6.1 = 3050 drives needed for 6.1pb

3050 x $80 = $244K on externals.
Then add in the cost of each nas server.

The current router I use cost $45 and can support 6 usb drives when using a $13 usb hub.

58 each X 509 needed = $29522 for the nas servers.

But of course if you were serious about building something like this youd be better of with direct connections to a hdd supplyer so would get massive bulk discount and would need a team to setup drive array in a rack system.

The Nas way I have my storage wouldnt be fast enough to full that much space in a life time.

Thanks. Looks like I'd need a data center rental as well. Hmmmm...

Why would you get 2TB drives and not 6TB drives? And externals? :rolleyes:

May I simply ask why? tongue.gif

Also, if it's only for long-term storage, you could use tape drives. They would be slow but a lot cheaper and more reliable than hard drives. You want extra hard drives/tape drives as well for redundancy. I doubt that anybody would run a 6.1 PB array on RAID 0...

Its of course super theoretical biggrin.gif

I guess its a matter of price and value.
Lets ignore for a second the price for bulk buys from a manufacture or directly from importer (if you buy hundreds of drives, might as well order directly from the manufacturer instead of resellers).
And lets look at newegg lowest price drives (not taking into consideration the raid requirements, performance, types or II or III sata connections).
1TB - 54$
2TB - 70$ - 35$ per 1TB (cheapest I could find there)
3TB - 110$ - 36.67$ per 1TB
4TB - 150$ - 37.4$ per 1TB
5TB - 250$ - 50$ per 1TB
6TB - 300$ - 50$ per 1TB

So in general, regarding price for value, 2TB is the best choice.
3050x2TB drives = 213,500$
1017x6TB drives = 305,000$

I would wait like 20 years. I'm sure price will be around $1000

Cheapest price per TB where I am, Strange how externals are cheaper then internals.
And set up as I out lined would never make use of all that space so stuff like this is just all theoretical.
But works well for set up I have which is only is only 2 drives at the moment but will expand to 6 if I ever need that much space.

My set up I only get 15mb/s write speed so lets take a look at how long it would take to fill up.
Code:
1000MB = hdd GB (yes I know real GB is 1024mb)
1000 / 15 = 66.66666666666667 sec per gb.

1000gb = hdd TB
66.66666666666667 X 1000 = 66666.66666666667 secs per TB

1000tb = hdd PB

66666.66666666667 X 1000 = 66666666.66666667 secs per PB

66666666.66666667 X 6.1 = 406666666.6666667 secs for 6.1PB

60 secs = 1 min

406666.7 / 60 =  6777777.777777778 mins

60 mins = 1 hour

6777777.777777778 / 60 = 112962.962962963 hours

24 hours = 1 day

112962.962962963 / 24 = 4706.79012345679 days

7 days = 1 week

4706.79012345679 / 7 = 672.3985890652557 weeks

52.1775 weeks = 1 year

672.3985890652557 / 52.1775 = 12.88675365943665 years

12.88675365943665 years to fill at that speed.
