Raid Array question

[Gilbernata]

Hello all. I have four older identical 160gb SATA II drives and four identical 32gb ssds. As well I also have two identical 250gb hdds. I have a raid card that supports up to 8 drives. It has 512mb of onboard cache and two batteries. It runs on a pcie x8 lane (which works perfectly fine on a regular x16 lane).

My question is, what would be the best possible raid set up with the hardware I have? As a side note I am more in favour of speed over redundancy. So what's the best possible set up for me, with as much storage as possible and as fast as possible? Thanks! Looking forward to hearing your answers.

If all you care about is speed and don't care about redundant or drive safety then just make a bunch of raid 0 arrays

Is it possible to have a bit of redundancy such as a stripe array with my ssds and a hard drive in each stripe (0-1 array)? Sorry this is probably a dumb question. The hdds and ssds aren't the same capacity.
