SSD or HDD for Mail Server ?
There're lots of performance benchmark for web / db server in terms of IOPS , but rare to find for mail servers.
I ran a small mail server (postfix/dovecot/rspamd) for 3-4 years on Linode vps, but now thinking to move to a dedicated server for a much bigger storage space.
Interested in AX line at Hetzner but couldn't decide if I need soft RAID-1 SSD (standard nvme/datacenter sata ssd/datacenter nvme) or 2 enterprise HDD's in soft RAID-1.
What do you guys suggest for a standard imap mail server which scan inbound and outbound mail ?
How about block storage on some vps provider (especially buyvm) , does it appropriate for mail storage ?
