The Ultimate All-In-One Storage Solution
karnifex writes "Filled up your LaCie Bigger Disk already, and looking for a little more storage space? Good news! The Petabox is ready! 'The petabox by the Internet Archive is a machine designed to safely store and process one petabyte of information (a petabyte is a million gigabytes).' And luckily, as the Internet Archive notes, it's shipping-container friendly (20' x 8' x 8'). So save on delivery costs and order two!"
From the article:

* The first 100TB Rack is up and running!
* The second 100TB Rack will be up by the end of May
Apparently this is some new use of the word "ready" with which I am not familiar. Neat technology, no doubt, but it doesn't really look like it's ready for prime time just yet.
In the "discussion" blocks down below there's a price link.
Rack materials cost is currently estimated to be $121K for 96TB. Node materials are a just under $1450. This price does not include markup, assembly or burn-in from the system integrator and thus will increase by another 5-7% to approximately $130K/rack.
The weight of a fully-loaded rack is estimated to be 1500 lbs. That figure may rise depending on what hardware is required for rack cooling.
Power is estimated to be 5500 watts. This too will depend on rack level cooling equipment.
These figures assume no external 1G Ethernet NICs.
For a breakdown of all the above, see the attached spreadsheet.

How many 128kbps MP3s can you store on it.
250-300 million depending on song length
And most importantly, how many floppy disks is this equivalent too?!
700 Million - nearly 40,000 miles when laid end on end, or about 1500 miles when stacked on top of each other.
How many 128kbps MP3s can you store on it.
... which works out to just about 1934 years without hearing the same song twice.
Glad you asked. Assuming that we have a 10^15 byte disk (which is how those decimal-loving hard disk manufacturers would define it), and your MP3s are encoded at 128kbps (where 1 kb = 1024 b = 128 B, as the binary folks would have it), then you could listen to MP3s nonstop for:
10^15B/(128kb/s * 128B/kb) = 61035156250 seconds

Power corrupts. PowerPoint corrupts absolutely.
The current genome build has a size of 3,020,300,000 bp, at 2 bits per bp and 5(?) spice girls, that's about 3.5 GB (uncompressed).
Of course with a mostly static database like that you only want to store the diffs, not the whole thing. The bulk of the diff would be SNPs, roughly 1 per 1000 bp: 3,020,300,000 / 1000 / 4 / 1048576 that's about 0.72MB per spice girl. An if you only store the ones actually different from wildtype you probably don't need more than 20% of that.
You can fit a Spice Girl on a floppy.

You're off by a factor of ten. Let google do the math: 1 petabyte / 100 megabits / second in days = 994.205393 days
