1 RAID or 2?

[texmaster]

I've got 2 10k rpm SATA drives at 130gb each and 2 32mb cache 500 GB drives.

I was thinking of going RAID 1 for the 2 10k drives for OS and basic apps and going RAID 1 for the 2 500GB drives for main storage files.

Is this the best way to go or should I put everything in RAID 5? Does that slow the 10K drives down to the 7200 speed and is it the most efficient way to go?

Thanks.

Sure.

No.

No, but you'd lose a lot of hard drive space on the 500gb drives, and I'd think your raid would perform pretty weirdly. You want to keep as many things as you can the same (speed, connection, performance, manuf., model, etc)

thanks for the input

why go with raid 1 in first place? do you need the redudency? you will have increased read speed but your write speeds will suffer.
