Is this all I can hope for?

This is copying a large file from my win10 VM to a share on the array. Low spots are at around 5MB/s. Disks are 1TB SATA.

Home network is 1Gbit, if it's using the network instead of communicating directly?

search "turbo write" or get a cache disk. Otherwise, that is it.

Form win10 I can get around 110-90mb/s with SSD cache drive I have turbo write plugin installed also

Will check out turbo write! Thanks!

(I have SSD cache disk).

I've been struggling for years to get decent write performance to the ssd cache but I'm in the same boat as you. My copies and writes usually peak in the low 40s

With turbo write enabled I seem to get an extended period of good speed at the beginning, then dropping to 8-9MB/s, and ut to 50MB/S again, like the wave pattern above.

Still better than before I guess.
