General System Build Advice Questions
We get a lot of these so please consider the items listed below before posting.
If you are just asking for advice, especially about building a system of your own, Have you searched TrueNAS forums first. There are a bazillion postings about building a system. The most important part is this question: What is your use case? This means what are your intension’s’ for this system build? Just a NAS, a Media Streaming Super Computer, Block Storage, etc. If you are unclear on the exact terminology then take your time and explain what you desire.
Create a listing of your system Requirements and yes, write them down as they will likely change as you determine what you want.
A. Capacity
B. Network Speed
C. Access to data speed (how fast the drives can present the data)
D. Will you be supporting iSCSI
E. How many people will be using it at the same time?
F. Think about everything and put that list together, only then will you be able to shop for the correct parts to build this system. And if you think you will be able to do this on an old Amiga computer, that will not happen. If you need a serious NAS, buy proper components. The drives and fans will be replaced and are considered consumable, the other parts are likely to last for the duration of the project you have in mind (10+ years).
G. Cost. This is a big factor but please understand, you will unlikely find a high speed machine that is quiet and cheap. The above listed items should be the priority first.
