Those following test are not accurate for many reason : I don't have a good internet connection, I've several p2p softwares connected at the same time (BTC core, SIA, STORJ share, MAID) and a lot of internet page are open on my computers (>60). MAID alfa only allow file of less than 25Mb so I used this file to run my test : Name: aaabbb.zip, Type: application/zip, Size: 24848251 bytes. I ran storj on debian, sia & maid on w7. I used default setup for all. Those test are for me just a photo of what's available today, but they are all moving fast to improve their software, feel free to run your own test and share it here
