Easy to beat a 747
A rackspace portable storage center fits 12,000 hard drives (=36Pb) of data, into a 40ft shipping container.
A container ship like the Emma Maersk can carry 15,000 TEU (20foot containers) across the Atlantic in 5days
So 12,000drives * 3Tb * 7000 containers = 250 million Tb, and it takes 5days = 450,000 seconds
So a data rate of 250,000,000Tb/450,000s = 600 TBytes/s
Although you do have to watch out for pirates!
- Retric 14y agoA Boeing 747 LCF http://en.wikipedia.org/wiki/Boeing_747_LCF http://en.wikipedia.org/wiki/Boeing_747_LCF can cross the Atlantic in 3.5 hours and carry 180,530 kg. 3TB drives weigh ~1 lb = 180,530kg/1lb * 3Tbytes / 3.5 hours in seconds ~= 235TBytes/s which is rather close. Especially when you consider how long it takes to load those container ships and how limited the destinations are. PS: As to pirates your 84 million drives at 150$ a piece would be worth ~12.6 billion dollars which might actually be a tempting target even if you can only get 10% of their actual value in ransom. Edit: Even this is small next to MicroSD cards. ~64GB/gram = 29Tbytes/lb = 2,270Tbytes/second across the Atlantic for ~12.64 billion.
- tcpekin 14y agoHow did you do get your result? I calculated 758 Tbits/second [1] or 95 Tbytes/second [2]. I think you or I may be missing a conversion somewhere.

- Retric 14y agoHeh, I just did it again and got your numbers so I think I made the mistake. PS: It's off by ~2.4 so probably did the kg -> lb conversion twice + some rounding errors. Let's see if I can redeem myself Heathrow Airport averages a little over 1300 flights per day. If 1 flight can handle 1.2 million TB's http://www.wolframalpha.com/input/?i=180%2C530kg%2F1lb+*+3Tbytes+ http://www.wolframalpha.com/input/?i=180%2C530kg%2F1lb+*+3Tb... then Heathrow Airport in theory is a router than can handle 17,965 terabytes / sec http://www.wolframalpha.com/input/?i=180%2C530kg%2F1lb+*+3Tbytes+*+1300+%2F+24+%2F+60+%2F+60+in+Tbytes http://www.wolframalpha.com/input/?i=180%2C530kg%2F1lb+*+3Tb... (Not that they are setup to handle freight, but at least flight time is not important only throughput.)
- excuse-me 14y agoBut the rackspace containers you just need to hook up power and water - then you are done!
- excuse-me 14y agoI think 3.5 hours is probably Concorde rather than a 747. I was thinking that a gaziilion terabytes might be more tempting for the piratebay.org
- Retric 14y agoDepends on where your taking off from but (YYT TO SNN) http://flights.expedia.ca/flights-from-st-johns-to-shannon-yyt-to-snn/ http://flights.expedia.ca/flights-from-st-johns-to-shannon-y... = 1940.10 miles at 600MPH your at 3 hours 14 minutes not that there are any direct flights between those airports, but if your spending 12 billion on micro SD cards, I think you can charter an airplane and spend extra fuel going a little closer to top speed vs cruse.
- excuse-me 14y agoSlightly off topic, but have you played with this site http://www.gcmap.com/mapui http://www.gcmap.com/mapui It shows great circle routes for any pair of airports, with ETOPS, actual routes etc - great fun if you wanted to know why you are over Iceland
- brazzy 14y agoI wonder how big a fraction of all the harddisks in the world that would represent...
