How much $ does it cost in Mb per second*Gbyte capacity?

http://www.supertale...s...ive USB 3.0
http://www.amazon.co...s...424&sr=1-19
http://www.amazon.co...s...496&sr=1-47

let's see:
Average RW=0.5*(130+43)=86.5
72/(86.5*16)=0.83

Plain $/Gb=72/16=4.5

120/(86.5*32)=0.043

Plain $/Gb=120/32=3.75

http://www.amazon.co...i...496&sr=1-35
http://www.amazon.co...i...496&sr=1-26

Average RW=0.5*(316+142)=229
255/(229*32)=0.034
Plain $/Gb=255/32=7.97

365/(229*64)=0.025
Plain $/Gb=365/64=5.70

595/(229*128)=0.02
Plain $/Gb=595/128=4.65


Not very expensive unitary prices :), but this is an example of something else you can buy with the same 595 US$ of the last example (and a handful of bucks more):
