I have a 8 core server that has a hardware raid card in it I am wondering what raid I should use out of raid 0,1,5 and 10 the drives are 4 15k sas drives.  It has two 1 gib nics in it and I am wondering the optimal setup for it.I dont plan on saving any important data on it. Thanks!

If its a server, Raid 1 or 10 would be your best option to protect the data and its integrity.

If theres no important data,you can RAID0 them for maximum performance and 100% space utilization - but to make recovery of your files easier, you may be better just to run them in JBOD and span a volume across all the disks in your OS. 

 

RAID0 = striped. distributes your files across all disks. 100% space utilization but high risk

RAID1 = mirrored. all of your data is held on one disk and mirrored to another. 50% space utilization but protected against disk failure. (for 2 disks)

RAID10 = mirrored + striped. your data is mirrored across 2 striped arrays. 50% space utilization (4 disks or more)

RAID5 = parity. your data is striped across the disks, but you give up 1 drive for parity. You lose 1 disk worth of space, but have protection against a single disk failure. 

 

Up to you which one you think is the best in your case....

I'd probably personally do a single RAID10 volume, or two RAID1 volumes. It would entirely depend on whether I wanted a logical separation of two separate drive letters.

 

Eg: I might do:

1x RAID1 (2x drives) -> Install OS and applications/services onto this drive

1x RAID1 (2x drives) -> Share this drive as your "NAS", also save data here (eg: movies, music, documents, etc).
