There are 3 things to believe when employing a plotting drive to farm Chia.
1. Total Storage
A single plot can take up to 370GB of storage while it’s being created. this suggests 1TB of storage supports 2 plots being generated at an equivalent time. If timed appropriately thanks to different phases using different storage amounts, it can reach 3 plots.
2. Read/Write Speed
Plotting is usually bottlenecked by read/write speed, and other people report traditional hard drives taking twice as repeatedly as SSDs.
However, M.2 NVMe drives are incredibly fast, often over 3000 MB/s while SATA SSDs are often at over 500 MB/s and traditional HDDs around 80-150 MB/s, maybe 200 MB/s on the high end.
It’s important to notice that using an M.2 NVMe drive externally during a USB 3.0 enclosure may be a viable plotting solution, but is restricted by the read/write throughput of USB 3.0 of about 400-600 MB/s. Using USB 3.1 can get this up to over 800 MB/s.
Lastly, most SSDs are slower as they need to sustain the read/write operations and thus sustained speed is more critical than the advertised speed on an SSD. Some SSDs will bottleneck your plotting process thanks to worse sustained speed.
3. Device Lifespan
The plotting process writes tons of knowledge , which reduces the lifespan of a drive. especially , SSD has limited read/writes before they’re likely to fail. So an SSD can plot quickly, but an HDD lasts longer before it must get replaced .
The thing to believe here is to seem for SSDs with a high “TBW” or Terabytes Written. Some consumer SSDs could also be as low as 200-600 TBW before they’re susceptible to failure, while other drives can last up to 3600. You can also order pooling enabled plots from chia plot online .
