@sis111 I plugged in 8TB in http://burstcoin.biz/calculator and it gives $0.32 of profit per day, or 562 days to ROI if the drive costs $180 USD.
Burstcoin rewards are dropping as time goes by, plus you need electricity to run it. It should ROI before the 3 year warranty ends if nothing drastically bad happens, and perhaps in 1 year if prices go up.
There are a couple of decentralized file storage apps that should mature over 2017 so that's another use for the drives.
