Many manufacturers offer product sheets. You can also use price comparison websites. They sometimes offer an easy way to look at the specs or even compare them side by side.

Some hard drives are built for 24/7 operation. They have higher MTBF ratings and longer guarantees.
Hard drives are very different. Many of them waste energy, lie in the SMART log or just are weird (spin up and down, lose speed, get incredibly hot etc.)
I’ve been self-hosting Postfix for several years and it’s not difficult, if you’re absolutely confident what you do. I don’t recommend it if you don’t know basic behaviors and internals of SMTP and relaying. Also you need to know how to secure your server so you don’t get spammed a lot and getting hammered with brute force attacks.
From time to time you need to react to delivery problems. Most interesting one is perhaps Microsoft, which you need to ask to whitelist your server or your email won’t be accepted.
I recently removed my 25Gbps PCIe dual port cards from my 2 servers because they were using 20W more. My entire rack including 2 UniFi PoE connections uses 90 W now (so 110 W just for having 25 Gpbs).
There is some heat from such cards, but usually it gets transported outside fine. The ones I bought did not come with a fan. I think you cannot operate them without one. The heat sinks get very hot.
It’s so easy to work around an audit. Companies lie. Auditors are being bribed. Everything is based on trust.
Did you use iperf
? It makes sure that HDD/SSD is not the bottleneck.
You can also check the statistics and watch for uncommon errors. Or trace the connection with tcpdump
.
Are you looking for something like cached credentials?
