If your talking about Write Caching on SD card you can implement it directly:Is there a caching program for the SD card?
For example, 500MB cache of the SD card on the SSD. Something like how SSHD works. That would hugely boost the speed.
I tried PrimoCache but it crashed the whole SP3 every few minutes.
In File Explorer, Select the SD card, right click to Properties, Hardware, SDXC card, Properties, Change Settings, Policies, Write Caching Policy
