3 Vertex's will probably be around that speed. Even if they are slightly capped by the ICH10R it will make very little difference TBH, especially for RAID0 use. If you got a 4th drive the PERC6 would be much quicker than the onboard though. For a very slight possible gain you have to pay for the 10-15W that the PERC will put out (both in terms of the extra cooling/airflow required, and the power bill).

For best performance, the caching on the PERC might help a little, although for Vertex drives it probably won't do much. For slightly fewer headaches it might be better to use the onboard RAID for booting from a 3-Vertex RAID0 (as booting from RAID cards can be troublesome, especially on desktop boards, and even more so if you also use the onboard RAID functions or have NICs with a BIOS).

To update the SSD firmware I would advise you to use the onboard ports, without any RAID set up at all. For more info you would be best off checking out the OCZ forums.

I meant the FW of the SSD's, not the PERC itself.
Just follow Tony's post on the OCZ forum Link

You'll just have to try both the ICHnR and the PERC.
The PERC might show better throughput and the ICHnR might be better on IOPS.

I've used the Vertex on the PERC but as I've only got 1x60, 1x120 and 1x250 I never used them in a raid config. (except for testing)

Why is that?

No need to worry, the PERC is performing really well with SSD's ;-)

IMSM's caching (when turned on) can sometimes work wonders and in some benchmarks IMSM outperforms most hardware controllers.
Real life performance is a different thing.

I'll see if I can dig up some examples on this matter.

IMSM utilizes system memory, correct?

If you're running RAID0 or RAID5 with 4xF1s, you should be getting closer to 350MB/s or 280MB/s respectively.
all right i did a little more testing found some interesting results

i got hd tune 3.10

and changed the block size from 64 -8mb and there are the results
block size - avg
64kb-125mb/s
128kb-169mb/s
256kb-284mb/s
512kb-359mb/s
1mb-373mb/s
2mb-371mb/s
4mb-374mb/s
8mb-372mb/s

this was on a faster setting cause i have a life so there might be a little error

which one of these results would be considered the most accurate
and why such a large range
and why do people that run 2.55 with a non changeable size seem to get better results
and is there a normal setting to run it on considering no one usually mentions what they run it at

sorry for lots of questions but now im curious

Apparently it uses system memory for it's write-back cache.

Cool man, thanks for the info! At first, I was planning on using my PERC, but now I think I'll just use my onboard controller, seems easier...as soon as I figure out how to use that, LOL! Never used it before.
I planned on updating the FW before I set them up in an array, but I thought I read somewhere there's a way you can update the FW without breaking it, do you know anything about this?

Thanks again!

Never actually seen another cable like that so it would seem to be your only option. All the SAS cables I have use standard 'molex-type' peripheral connectors.

As you said i haven't found any SAS cables that use sata-type power connectors but only cables with molex-type power so i guess i will have to order them and i will see for myself if there are the correct cables to connect my Savvio on the Perc 5/i.

Yes. Combine that with X58/DDR3 and you have an insanely fast write-back cache. I have seen burst speeds up to 1500MB/sec on my onboard RAID0
