32 TB of drive is slightly MORE expensive (at NewEgg pricing on the Seagate Externals) than most GTX 1080 ti cards - which pull in close to $3/day each at this point.

i don't see how it's comparable

on http://burstcoincalculator.com/ 32TB are giving only 94 BURST/Day so 0.82$

and if i'm looking on nicehash profiltability calculator:

https://www.nicehash.com/profitability-calculator/nvidia-gtx-1080-ti?e=0.1¤cy=USD

gtx 1080 ti is giving after deducing electricity 2.24$/day

you need at least 120TB to make 3$/day and 8tb cost ~ 200$ so you need 15 disks for a cost of 3000$

it's a lot more expensive than a gtx 1080 ti

i'm missing something ?

I didn't say it was comparable - you're arguing MY case that it's not - unless you have a VERY HIGH electric cost that makes GPU mining prohibitively low on profitability.

With that said, the nitpicking 9-)

You DID forget to factor in the electric usage of the hard drives, 120 TB of Seagate Externals = 16 drives (they FORMAT to 7.27 GB not to 8GB on both the Archive "Backup" version and on the Compute "Expansion" version) probably average 8-10 watts each (peak usage is about 12 watts per drive as I recall the specs but they're not accessing most of the time which will drop that - but the platters keep spinning which uses a lot of the power they consume on 12VDC).
128 watts at MY power cost however is only pennies a day - but it IS barely into the double-digit pennies a day - while 160 would still be under a quarter per day FOR ME.

BURST calculators are notorious for being optimistic, which seems to be due to how the "network TB" figure is calculated.
Pools seem to only count the "machine that most recently submitted a share to an account" on the total TB of that account, there are times the pool I uses says I have well under 1 TB of hard drive mining when my total is well over 20TB.
In my exprience, you need to DISCOUNT the "estimated return" any BUST calculator comes up with to a little over HALF, perhaps as high as 60% of it's estimate, to come up with a REAL figure of any accuracy.

You also should keep in mind that electric COST varies a lot - mine is some of the lowest in the USA, nowhere near the Nicehash 10cents/kwh default - which is a plus for GPU mining where I'm at.
You probably deducted more for electric usage than I actually have to pay.

Nicehash also badly underestimates the Equihash (ZEC) hashrate of the GTX 1080 ti at 630 sol/s.
I'm seeing more like 760-770 right now out of my Aorus on the same EWBF 3.4b miner Nicehash uses in it's recent Legacy versions.
Oddly enough they DO seem to use 250 watts as the power usage for the card, which is where mine is set at - a 1080ti pulling 630 sol/s is probably only using 150-180 watts of power.
