Using Gen2 and Gen1 drives in same array?

Is it wise to do this?

I have 4 g2 and 2 g1 drives here and I've put them on a raid0 array together. I'm noticing some strange benchmark results though like on ATTO some of the sizes like 128 and 256 are super slow compared to the rest.

It seems to be performing pretty well though. But should I image this and replace the g1 with g2 drives?

You have six Intel SSDs in a single RAID0?

What RAID controller are you using? The ICH9/10R gets bottlenecked at around 650MB/s.

I'm using the Areca 1880ixl-8 port. w 512mb cache.

Do you have your ATTO benches?

I have seen weird SSD behavior on RAID controllers though.... i.e. A PERC 5/i and 6/i can actually limit IOPs.
