Magnetic media To the data transmitted from one machine to another machine, one of the most common way to write data on tape can be erased by the other media (such as Keke machine DVD), then use physical method to tape or disk shipped to the target machine, and then read out the data. This method does not like the use of geostationary communication satellites is less complex, but its cost is often very high, namely, high efficiency, low-cost, especially for those who require high bandwidth or before, or take into account a transfer fee for each application system . A simple calculation can be done to make this point very clear to see more. Industry-standard Ultrium tape can hold 200GB (byte) information. 1 60 60 60cm box that can hold 1,000 such tapes, so the total capacity of 200TB, or 1600Tb (ie 1.6Pb). By Federal Express or other express delivery companies in this case within 24 hours of tapes can be delivered to the United States in any one place. The effective bandwidth of such a transfer is 1600terabits/86, 400s, or 19Gpbs. If only a short distance from the target, then the bandwidth can be increased to more than 400Gpbs. Do not have a computer network such as transmission capacity can be achieved. For the banks, there will be a lot of data needs a daily backup to a second computer (so even though they face a big flood or earthquake, when the bank can continue to work), from a performance point of view, any other form of transmission Technology can not keep pace with the practice tape. Of course, the networks are getting faster and faster, but also increased the density of the tape. If we look at the cost can also be found in a similar situation. Ultrium tape wholesale price of about 40 U.S. dollars. A box of tapes can be reused for at least 10 times, so every time you use the tape in each case the cost of almost 4,000 U.S. dollars. Plus transportation costs 1000 U.S. dollars (probably even less certain), we can calculate out the cost of shipping 200TB about 5,000 U.S. dollars. In so doing, transport 1GB of data less than 3 cents. No one network can compete with it. The inverted sub-implied meaning is: Do not underestimate a full tape, speeding truck on the highway bandwidth.
