Greetings,

I currently have a 3-drive RAIDZ1 pool of Crucial MX500 1TB SATA disks (CT1000MX500SSD1).
I also have another, M.2 Crucial MX500 1TB disk (CT1000MX500SSD4), not in the pool, of which i find no info on.

I intend to redo the pool from scratch and, as far as fdisk is concerned, these 4 are identical in all but model name.
The board is a Asus Prime X370-A and i’m sure there are speed differences between SATA and M.2, so the question is can i use the 4 together in a new pool? Can i use the M.2 as cache? Pros and cons? Suggestions?

    FYI, M.2 describes a form factor, and SATA is not. You can have a 2.5" SATA drive and an M.2 SATA drive, for example.

    Though yes, M.2 SATA drives are generally faster.
