Currently Jan 1 2022, my farm capacity is 750TB , 60% solo plots , 40% pool plots.
I did not want to erase solo plots. When I add new drives, I'll use pool plots.
Last year 2021, start farming Chia around May 14.
I gutted few backup servers to housing Chia plots. Don' want to buy new drives for the Chia farm.
I farm and sold Chia, when Chia price dropped below $300, I stop selling and started holding XCH.
With the Chia earning. it paid for all the old drives that I already owned and money to buy new drives.
I waited and not buying new drives until Black Friday 2021.
Between Oct to Dec 2021. I spent $3,400
Purchased a used NAS system, U-NAS 801a with SM systemboard, included 4 x 10TB WD drives.
Purchased new 11 x 14TB WD drives
Purchased used 12 x 6 TB SAS drives @ $8 per TB
