"The researchers from University College London (UCL) in the UK achieved a data transmission rate of 178 terabits a second -- five times faster than the previous record.
The record, described in a research paper published in the journal IEEE Photonics Technology Letters, is double the capacity of any system currently deployed in the world."
In 2013 Netflix required massive amounts of fast storage and fast networking for streaming. At that time, it had 100 to 150 terabytes per server, which has undoubtedly grown massively since then. Netflix CEO Reed Hastings stated in 2015 that users had streamed 42.5 billion hours of video through the service.
