I’ve been in your shoes, Halex. Well, I’m actually still in your shoes.
I’ve been running my NAS on Windows 10 Pro for a long time since I didn’t know any better. I also use the PC as a daily driver, like you. Since joining this community, I’ve learned a ton about the value of UnRAID and why not to use cheap RAID cards (which are typically Marvell chipsets and have lots of issues). UnRAID will be everything you currently have, but so much more and will simiply work better.
Thanks to the advice and support from the serverbuilds community, I’m running an LSI 9211-8i HBA (with a SAS expander). It’s the best solution for expanding your storage, for sure. Lets you run SAS or SATA drives – and a lot of them! Way more than your mobo or a SATA card can.
You can virtualize your Windows installation to run within UnRAID. You don’t need to build a separate rig. Everyone here will help you get setup. You’ll still have your Windows daily driver in a VM running on top of UnRAID, but you’ll have this super powerful NAS OS underneath with data protection for your files and the ability to run different services in Docker.
Again, I came from your point of view. I thought, well Windows has worked for me for so long, why change. Then you realize the quirks and limitations of Windows that don’t exist with UnRAID. After joining this community, I was quickly and overwhelmingly convinced that I could make a ton of improvements to my setup by moving to UnRAID.
In short, you want an LSI HBA (or the Adaptec that JDM recently reviewed), not a RAID card. And it’s highly recommended that you move over to UnRAID. I’m in the process of doing so myself.
