Second test is done
chia plots create -k 32 -t /temporary/temp1/ -2 /temporary2/temp2/ -d /run/media/lv/Pocket/dest/
First temporary is internal NVME, second temporary is SATA SSD in external enclosure, destination is external HDD
Total time = 23530.325 seconds.
Disk usage
Looks like previous for phases 1 and 2, but in 3rd phase space decreases faster.
Difference of first temporary usage:
Memory allocated
No visible changes, same as previous
TWB
Total TWB of NVME device used for one plot is 1 342 493 MB (81 892 MB lower)
Conclusions:
- Using secondary temp folder on another drive decreases TWB of faster device for about 80GB per 1 plot, so using cheaper and slower SSD will save some money.
- Using secondary temp folder on another drive increases available space starting from phase 3, so starting next plot seeding from that moment (or a little bit later) would be greater for queues. Especially for Samsung 970 PRO and 980 PRO series (or similar)
