@kn9ts said in Does the speed of the reading and writing of a Hard drive cap the speed/time of writing plots?:

So I'm wondering what if I bought an NVMe SSD with a read/write speed of 2100mb+/s, would this be even x10 to x20 faster in writing plots?

The Intel 750 SSD DiCs max out at 1.2Tb capacity. They are very (very) fast, and designed for demanding commercial applications, so quite robust (with a long Warrantee) However, each one costs about the same as two good 10Tb drives. And they take up PCIe slots /lanes (even with the U.2 variant, or M.2 adaptor).

But Luxe is right, the bottle-neck is then transferring Plots to the HDDs, with multiple cycles per drive. If the farm were big enough, then it might be worth setting up a couple of Raids, with 3x 4Tb SSD in each set (for example). But that ain't cheap either.
