I'm looking to replace a small server running Windows Server 2019 for a client who wants to stick with Windows Server Standard 2025. They prefer not to go with cloud solutions. The new server should have a storage capacity of 1-2TB and require some level of fault tolerance. What hard drive configuration would be best these days?

For smaller clients, cost is often the biggest concern. My best suggestion would be to use three 2TB SSDs in a RAID 1 configuration with a hot spare. If you're going for a hardware RAID controller, you can even run the OS on that array too. Cloud backup would be ideal, but if it’s off the table, just make sure they understand the risks of not having one.
For a solid setup, consider using RAID 10 across four drives. If you're not opting for hardware RAID, Windows Storage Spaces can work nicely too. Just remember to run a backup solution like Veeam to keep data secure. RAID 10 is great because you get redundancy for one drive and top-notch performance, unlike RAID 5 or 6 which can slow down write speeds. Definitely my go-to recommendation!
Have you had positive experiences with Storage Spaces? I've run into a few stability issues using parity drives on lesser hardware, but switching to a mirror configuration worked well for me.
Absolutely—RAID 10 is definitely the way to go!
You should definitely explore the idea of RAID 5 or 6. Just be cautious—some might suggest RAID 5 for smaller servers. But I'd definitely focus on the RAID controller specifics that fit your needs!
I agree, RAID 5 can work but I'm curious about which drives/controller you’d recommend for that size.
Using RAID is likely your best bet here. Just keep in mind that fault tolerance is not the same as having a backup! Choose your RAID components carefully, and make sure you won't run into issues down the line.
Which exact RAID components do you recommend, down to the manufacturer?
It seems like you’re asking for specific hardware recommendations, but it’s tough to guide you without knowing which physical server you're using. Just so you know, RAID 5 isn't great for reliability—better avoid it if possible!
I think RAID 5 is fine for this setup, but really need to nail down the controller and drive recommendations.

Great idea! Which RAID controller do you recommend?
