March 17th 2018. Just for reference.
Just downloaded the entire blockchain.
Number of blocks: 513,962
Download time: 2 days 3 hours
Size on disk: 172GB
Used an Amazon Web Services EC2 t2.small server instance, running Ubuntu. 2GB memory. Was struggling a bit, hence the download time. CPU running at 100% constantly. Memory was fine but I think more would be needed if running a faster processor. Not sure of the CPU specs on the t2.small instance but it's one of their lowest performing (and cheapest) instances.
I tried to download it before. It keeps on getting rejected and I just notice that the space isn't enough. An excellent information sir, I'd be very careful with it's infos soon. One question though, did you pay or were there any payments done for you to completely downloaded it? Thank you.
