    UCL researchers break records with 178Tbps data transfer

    Used existing fibre infrastructure but upgraded amplifiers (at 40-100km intervals).

    Quick bit of looking tells me that Netflix US has ~36k hours of footage, so unless they mean 'all of Netflix, at 480p', it's wrong.

    "They use 36 drives that can hold about 100 TB of data. These servers are capable of storing and streaming between 10,000 and 20,000 movies simultaneously. Netflix has about a thousand of these spread across the globe"

    or Netflix super compresses their videos using propriety software then 'un-RAR' them on the fly using powerful CPUs/GPUs

    I would imagine it's not an exact figure for the whole Netflix library. I mean it's also localised isn't it. I've heard the 100 tb figure bandied around before though so I reckon around 100 tb of localised storage is about right. I would also imagine it's 100tb compressed as compression usually takes longer than decompression.
    Old puter - still good enuff till I save some pennies!

    It's one 100TB drive x 36 drives per local server, though.... times "about a thousand", making the entire library 3.6million TB.

    Does not matter, Netflix has not got a 178Tbs connection to internet lol they will be on a Content Delivery Network caching all over the place so until all those places are served by such highspeed connections then each server is only going to have 1/10Gb backbone potentially so downloading will be more like a bittorrent system pulling data together from multiple stream/links.

    Prob still take days lol

    There were no available 100TB drives in 2016 (possibly tape drives, but those won't be useful for netflix). They mean 100 TB across the whole array (although it's probably got more storage these days)
