i recently start working in a new (small) company having an "old" file server with windows server 2003 and an hw raid 5 with four disks. Last week the server is dead. We decided to build up a newer system with windows server 2008 using a PC with this hardware : CPU: Core i3 3,2 GHz RAM: 2GB Motherboard supports Raid. (we can't use the hw controller from the first server)
Examining the disk configuration i not sure about which one could be better for us between a Radi 5 with 4 disks (as in the past) for OS and Data, or two distinct Raid 1 (one for the OS and one for the Data).
We have about 60 users and about 10%-15% of them could concurrently access the server.
Moreover, in these scenario it is better an hardware raid controller or the "fake" onboard raid could be enough.
Thanks.
