Main PC:
On my main "daily driver" PC I use 2x250GB SSDs in raid 0, this gives me super fast 500GB, plenty of room to keep my Steam games and have super fast response. I don't care about the lesser reliability of a raid 0 setup, as I use my File Server to keep important information. All I need is fast performance. I don't mind re-installing windows or re-downloading steam games if needed, but i haven't had to so far. Been running for about a year on this setup, so far so good.
File Server:
On My File Server, I have 8x3TB WD Reds, and 3x2TB WD Greens.
The 8x3TB WD Reds are setup in Raid 6, from a LSI raid card, in case I need to move my raid array to a different motherboard.
I built this NAS to keep all the media for my whole house, so I want it to be rock solid, and built to last. So on top of the crazy good reliability on the WD reds I set them up in raid 6 so in the off chance that 2 of the WD reds fail, all of my critical data will still be save.
The 3x2TB WD Greens are setup in raid 0, off the motherboard raid controller.
I use this as a sandbox space, for none critical network storage. Browser downloads, and such.
this server runs an ssd as a boot drive... mostly because I had it laying around... no real need for an ssd on this server.
