SSD caching for recent photos and NAS HDD storage

[Quentame]

Hi !

Situation
The Immich instance is on a Raspberry Pi with 1To of SSD storage and I have a NAS of the same network.

Quention
Is it possible to use the Pi's SSD for hot storage (Recent or frequently accessed photos) and the NAS HDD for storage (all photos) ?

Goal
Make the photo access much faster for recent ones by using the SSD as a cache, while storing all photos in the NAS (main storage).

If already possible
Do you know how to do that ?

Thanks !

No. You can put the thumbs on an SSD

I would also really want this feature. New files on SSD, and older moves over to HDD.

My problem is that the HDD would needs to wake up and spin up every time I take a photo with my phone, unless I choose to delay my uploads in the phone app. I want direct upload and mostly silent disks.
I am still mainly on SSD for immich, but with the current ssd-prices there is soon not enough space left for me =(

I'm using NFS with FS-cache for that purpose. Works nicely although I haven't really benchmarked it.
