SSD Sata in cache ?

Go to solution Solved by flyride,


Hi, guys,

Just a simple question, I'm thinking of buying 2xSSD sata for the passthrough at xpenology.


I just want to make sure that the SSD cache also works with sata disks and not just NVME disks.


Thank you & Sorry if the question has already been asked.

Yes, SATA works fine for cache.  Be advised more RAM is probably better than SSD cache for most workloads.


R/W cache exposes your array to crash-induced data loss.  R/O cache is okay.
