The cheap consumer SSD are wasteful for this anyways. Their performance is horrible when doing a lot of writes. Once their cache fills up, they tank. You're better off buying a bunch of small used hard drives on the cheap. Creating one plot per drive.
I've been toying with it since I have a lot of extra storage. While it's too late to make much money. I may as well let the drives partially pay for themselves and destroy plots when I need more space for my file server.
Anyways, I've found a single old 7200RPM drive beat the plot time of a cheap SSD. It takes about 12 hours on the same system (i5 3570K, 16GB RAM) with the same plot settings vs 14 to 16 with a cheap SSD. I've even set them to plot at the same time, thinking I was wrong, and the 7200 RPM drives would pull out ahead. Hitting 100% complete when the SSD was around 70%.
Using two 7200RPM drives in RAID 0 takes 8 to 10 hours (i5-2400). That's getting closer to the times of my Samsung 980 (i5-11400) and dual Samsung 870 Evo in RAID 0 (i5-11400). Just as good as my Crucial X8 using USB 3.1 Gen 2 (i5-11400). That's with everything set to the default two threads 3.5GB RAM. Obviously the good SSD pull out with more threads. But it reduces the number of simultaneous plots my CPU can handle. The cheap SSD it didn't matter how many threads or how much RAM I gave it.
To be fair each of those high performance SSD are working two to three plots at a time, staggered. That just means with a bunch of cheap old HDD set in RAID 0 pairs. Working one plot each. You can get close to a decent sustained write SSD. All for a lot less money without worrying about wear. You just need the ports.
For anyone curious about heavy write performance. Two 512GB Samsung 870 Evo in RAID 0 beats a single 1TB Samsung 980 in plotting. A Crucial X8 1TB is really disappointing.
