Can an SSD cache act like an optane drive for disk and parity drices?

Hi all,
quick question.

I'm new to Unraid and I'm using it as a professional 3D artist working freelance. I needed a huge NAS but also with fast read write.

At first my NAS was very snappy because it was all SSDs. Now I have a more complex setup with a 10TB drive as parity and 10TB drive as the disk. I have a mix of SSDs in a cache pool which effectively gives 6TB of SSD.

I noticed very good performance when writing to my unraid NAS. But after the next day, when the cache data is moved to the disk, I experience extremely slow read performance.

The dream is to have
- High capacity storage
- redundancy
- cloud backup
- high read write speed
- can work on PC, MAC, Linux
- an fpt and media server accessible from anywhere.

So far I love Unraid, but I wish there was a way to use the SSD cache like optane. (I did very basic research on Optaine). It may be a preference to use the SSD pool as a storage place for commonly accessed files to enhance read/write performance.

Is this possible or am I talking stupid?

Would love for Unraid to be more performant for artists who seem to need everything.

Thanks
Steve

What you want is not possible.   However an alternative approach (as long as you are on the 6.12.x release) might be to use the 2 10TB drives in a ZFS pool instead.

Cool thanks for the reply, I will look into this ZFS suggestion.
