Can you do multiple RAID levels on a single RAID card?

Like if I have a RAID card that can support 16 drives can I put like 4 in JBOD 8 in 0+1, 2 in 5 and 2 in 50 (just an example.) Or Do they all have to run the same level.

For SCSI depending on the card - yes. I do not know if SATA has that ability.

What controller do you want to use?

RAID 5 requires 3 hard drives. You would probably have to do some research on different RAID cards to see if they support multiple arrays, or if you have enough PCI slots, use multiple RAID cards.

I just wanted to know whether or not I could do it before I started setting up a specific system.

I was just trying to give an example of what I meant.

First off do you want Serial ATA, SCSI, SAS or IDE?

They have motherboards with 2 sets of SATA ports. Total of 8 drives, add in mux's and you can have 16+ drives.

I was actually gonna ask if my motherboard supported 2 types of SATA could I use multiple cards and the onboard sata or would the board disallow the onboard sata when the cards were introduced.

No you can add on cards and still use the onboard sata as well.

Most boards have 4xSata150 and another 4xsata300. Both usually support raid. I believe you can even raid across the 2 seperate sata controllers as well if I am not mistaken.
