Check the calculator again. I'm at 40 to 50 TB (lost count) and i think i'm getting like somewhere between 10K and 20K burst a day on average over a longer period (solo mining). sometimes it is days between i win blocks (which give like 7000 or so each atm.) sometimes i get 4-5-6 blocks in a day. but over time, and counting in snafu's with the hardware, i would guestimate i average about 10 to 20 thous. burst a day using 40 to 50 TB. that's way south of 6K for 1TB.
With having so much plotted how do you have this configured are you just using some device to attach them all to like usb hub etc or connected to computer and in rack layout
