I have a 2.3TB RAID5 I just configured today and it says it's gonna take 16 hours to initialize. I don't know why this is or what reason there would be to do it.

I was trying to equalize my RAID stripe with the NTFS cluster size, but that doesn't seem to be working right. 64K NTFS and 16K RAID5 stripe. That should work because it's a 5-drive array meaning there's only four drives with actual data (one parity) and that means 64/4=16. I think maybe because I did that it's taking this long to initialize or something else is wrong.

Umm I honestly do not understand half of that-LOL-The only possible reason that I can come up with is that sometimes windows 7/vista is very fond of scanning/formatting new drives whether they need it or not. It should not take 16 hours to intitalize a raid unless some sort of re-configuring/scanning/formatting is taking place.
Honestly though you are the one advocating SSD's-what are doing that needs RAID other than OS+a few Games?

You mean the first initialization, or when it initializes every time the computer starts up?

Onboard RAID, or a discrete card?
