The correct configuration for Proxmox

[Skrimer]

Hello!
For more than a year I use Proxmox! The first time I use a hypervisor and very happy!
Tried different configurations, but still can not come to one.

At the moment the configuration is as follows:
Proxmox on ZFS RAID 10 HDD + logs, cache and swap on Intel DC S3610.
Now I bought 1.92 Tb 5200 MAX. I plan to use this SSD as storage for VM as ZFS storage and RAID10 HDD for backups.

Could you tell me, please, correctly whether I think?
Does it make sense to use Micron SSD for VM? Will it speed up the server?
Is it worth to put on generic ZFS file system? The lack of TRIM for Intel MLC memory is not as critical as for gateway c 3D TLC.
Had the experience of installing pny ssd9sc120gcda for VM. After 2 months under ZFS wearout = 100%

The main load on the server:
- file database (~4Gb ~10pcs) in Windows Server 2012
- small CRM
- site
- file storage (based on Windows Server 2012)

In the future I plan the transition to version 6.

Thank you in advance for any answers and clarifications!

With only one SSD for the new fast storage and regular backups to the HDDs you must know if you are okay if you lose all the data until the last backup if the SSD fails. Don't forget the time until you restore the backup and have the VM up and running again.

For the speedup: most likely yes but it depends on your load. Test it out.

If you want ZFS with TRIM upgrade to Proxmox VE 6 which comes with a current ZFS version where you can enable it
