Siemens Reaches 107 Gbps Data Transfer Record 161
prostoalex writes "Reuters is reporting on Siemens engineers reaching 107 Gbps data transmission record over a fiberoptic cable, and expects the technology to be on the market within a few years: "The test, 2.5 times faster than a previous maximum transmission performance per channel, was done in cooperation with Germany's Micram Microelectronic, the Fraunhofer Institute for Telecommunications and Eindhoven Technical University of the Netherlands.""

But really, if an Aussie ISP (internode for instance) has just upgraded from 3Gb/s to around 6Gb/s, how much would it benefit them if they could just sell off most of the fibre they are using currently and just run one at 107Gb/s?
As for 25MB/s, a newer HDD will easily reach around 40-50MB/s, added with the popularity of NAS and small raid systems most good PCs can suck almost 70MB/s (560Mb/s).
Of course, with Australian broadband being lucky to get (until just recently) above 1.5Mb/s this is rather moot.

Maybe you should upgrade that machine you bought four years ago. :-)
A lot of drives today can write at twice that speed, and read even faster. I've got an external firewire 800 drive (a single drive, not one of the RAIDs-in-a-box setups) that can write at a little over 60 MB/s. Your point is, of course, still valid... few users are even able to make use of a gigabit - or sometimes even half of that.

Divide by 8 to get the number that makes sense. The "little b" stands for bits, and there are 8 bits per byte; the "big B" stands for byte.
1B = 8b.
The byte is the amount of data you could store on a single coin if you had a code worked out placing it either heads up or heads down. Ones and zero's.
