It seems that you can get HATs for the RPi that give 4 SATA interfaces if the USBs are not fast enough or you want RAID.
Not sure about Centos support.

Even a 4Gb RPi4 is pretty quick. For the price, very quick!

Personally, I use RPI 4B, with 4Gb RAM, SD 128Gb and CentOS 7.x, since they are available.

With the recent 8GB, it clearly changed my life, compared to 3B+ that I had at the beginning.

Hello together,
I've running a SOHO mailserver (postfix, dovecot, amavis, spamassassin, apache, nextcloud, mariadb) with fedora on a Odroid-XU4 for a long time. Since limmited RAM (2GB) OOM kills amavis 2/3 a day.
Now I'm thing to replace Odroid-HC1 with a SOC with more RAM

Is there any Hardware (SOC, no expensive Serverbords) that runs with CentOS8 and/or Fedora?
OS : CentOS8 and/or Fedora aarch64
CPU: min 4
RAM: min 4 GB
Storage: eMMC with SSD, USB3

Thoose boards on https://fedoraproject.org/wiki/Architectures/ARM are all armv7hl (=32Bit) and on https://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64 are all expensive Serverbords.

Greetings
Andreas
