TRIM for raid is here ...(For Intel chipsets ;-) )

Hehe, enjoy! Was definitely a nice improvement for me going with a raid0 array.

u have to check the FF box, it will destroy performance since the empty sata is FF not 00 like on a mechanical so by filling the drive with 00 u just made it 10x worse since it will have to erase then write

Correct, as it only allows for pass through in AHCI mode or "RAID ready" not in pairs of SSD drives in RAID. More can be found here:

Let's hope soon as I was excited about the prospects too after buying one Intel 160G SSD last week. For me one will be plenty fast enough and I'll appropriate the extra funds for a vid card upgrade instead.

I know about checking the FF box, but as far as I know that only improves performance on OCZ SSDs. I've heard this kills performance, even with FF checked, on Intel SSDs, so I decided never to try it out myself :)

Guys just a question, I have a P5Q-PRO with ICH10R, I'm not sure if the ICH10 and ICH10R are the same, but this means my chipset is included on the support for trim on raid 0?

Thanks for your help!

There is no TRIM support for RAID'ed drives. You only get TRIM support for SSDs that are not in the RAID but other drives are in a RAID. Before these drivers, as soon as you set up a RAID on normal HDDs but kept an SSD as a non-RAID drive you'd lose TRIM; this is what this driver fixes.
