Why do you say so? At 100 KB/s I can store close to 9 GB a day, which is not little.
In my particular case, it’s close to 1 TB/day. Then, in case of SAFE Network, if I don’t see the sucker reading more than 100 GB in the first week, I know it’s a lemon and I should kill it off.
Now, it doesn’t cost me anything (I’ve lost 8 days out of 365) to wipe this vault and try my luck again either on SAFE or on some Network B. In fact I should farm so that I parcel my farm in 20 chunks (say 1 TB / 20 = 50 GB) and bring those online gradually, using multiple storage farming networks (and terminate swiftly, if the ROI is crap), what I mentioned in this topic.
Even for people whose download speed is 100 KB/s, it would take 4-5 days to populate each 50 GB vault and another 4-5 to see if it’s any good.
