A 8tb drive makes about $18 a month now. Plug in 7270gb to this calculator:
http://burstcoincalculator.com/All in it's 10 months ROI and HDD is kinda like an ASCI because it only mines burst. Sure there's storj and sia but how many years will it take a fill hundreds of TB.
Past few months there were DDOS and their forum were down for weeks at a time. It's a lot more stable now.
It takes 14 hours to fill a 8 tb drive and another 14 hours to optimize it. Ramp up is slow. I got 12x 8tb drives, but imo money is better put in GPUs for now.
Does it make sense to run it on the same rig running the 5 x GPU? Would this affect hte performance of the GPU mining? (I'm using Nicehash). I have like $900 invested in motherboard, cpu, ram, power supply, operating system, spare ssd for system (in case other fails), 2tb backup usb drive, etc. So that something I wouldn't need to buy at least. All it would require is for me to spend $100 each for a few 4 TB HDD.
It has ZERO effect on GPU mining, even when it's doing the actual drive reads for the active "mining", unless you are trying to run it on a 1 or 2 core CPU - then the effect is small and short-lived.
SMR drives like the Seagate Archive line are pretty much PERFECT for BURST - you "plot" the drive once, and after that it's all READS from data that does not change.
USB flash drives work, but WAY BLOODY EXPENSIVE per TB - not cost effective at all.
The only machines I did THAT on were running small LINUX installations on "oversized" USB drives and I figured "might as well use the extra space for SOMETHING".
HDD on a "per TB" basis STILL blow away any flash drive.
