OK, so I just upgraded my computer to an MSI K8N Neo2 Plat/A64 3200+. I currently have 3 20GB Quantum Fireball HDDs (ahh, the good ole days) in the machine. Under my old setup, the way I had them arranged was with two of the drives in RAID 0 as the OS disk, and the single drive had my Documents and Settings folder on it (you have to make a custom install disc to install the folder to a different location). That way, I could keep all my d/ls and files and stuff in My documents and only ever (generally) have to back up my user profile to capture all my files, email, etc, but still have the cleanliness of having them on a separate disk.
When I was going about setting it back up, I thought about whether there was another better way to arrange these drives on my system (I do plan to get more storage space, but not for a while).
Here's what I came up with as possible options (all RAIDs/spanning would be done with nvRAID on chip):
Keep my current config (2 spanned/striped for os, 1 for Docs).
Span the 3 drives together to look like 1 big drive.
1 for OS, 2 spanned/striped for Docs.
1 for OS, 1 for Docs, 1 for Program Files.
2 spanned/striped for OS/Docs, 1 for data storage.
1 for OS/Docs, 2 spanned/striped for data storage.
So, what do you think I should do? Which method allows for the best combination of efficiency, cleanliness, ease of use, speed, etc.?
Thanks in advance.
