Warning

Since the release of Beta 14 on the 1st of October 2020. All the below data is outdated and obsolete. It only serve as historical data. One exception is the final .plot size of k values. To get some insight into the new features of the plotter check out this post in the Discussions forum.

k=32 is now the minimum plot size that will be eligible for mainnet at the end of the year. More here.

Plots larger than k=32

There was an oversight in Beta 14. For plots larger than k=32 the default buffer will not be enough to complete a plot. For k=33 a -b 3077 is the absolute minimum needed with the rest of the defaults. A -b 3139 will have better results by completing far more sorts in memory. More recommendations for 34-36 coming soon.

Various k size statistics - Current - Beta 8 thru Beta 13

These results from various machines should give a sense of how long and how much space a plot will take on different hardware. The first section is from Beta 1.8 or newer. Historical data is below and is currently still useful at the Beta 1.8 stage. Please add yours here or post the details in the #testnet channel of the Keybase Chat. The theory and process of plotting are described in the Chia Proof of Space Construction document.
