Quick question....I am setting up RAID 10 on 4 X 750 GB WD SATA drives, which gives me 1500 GB total space. I have created one Volume on the 4 drives. My question is what is a typical setup of partition(s) across the volume for OS and anything else that a partition should be setup for? How big should my partition be for windows XP, app, storage, etc? I should point out that this system is multi-use personal system. Main storage will be a SQL database for "one" db that will continue to grow (pretty simple, straight forward db), music, video/tv. This isn't a gaming server.

I posed this question to a friend of mine and this was his response:

On my system I have one big RAID 5 drive with 4 disks in it. I have several partitions on my disk.

System partition - mine is 100GB and I use this solely for operating system related things.

Shared Drive 300GB - This may not be relevant to you but this is a partition that I share with other members of my family. We put all downloads from the Internet etc. here as well as anything else we want to share among us.

Application Drive - mine is 100GB and I use it to install all application software, rather than taking the Microsoft default of installing on the system drive.

Backup - 100GB - I keep backups of all important files that cannot be easily recreated

I really could use some solid advice, and this is the last main component to deal with on my new system build. Thanks in advance.
